This guide will show you how to replace an air conditioner actuator on a VE Commodore. These actuators commonly fail on Series 1 vehicles and have been seen to fail on Series 2, however a revised unit is now being used.

There are multiple actuators behind the dashboard controlling modes, temperatures and air sources. Our guide will show you how to identify the faulty actuator and the steps to replace it.

HVAC = Heating, Ventilation and Air Conditioning

Common Symptoms:

  • Vents stuck in a certain mode such as feet, face or demister.
  • Loud clicking noise behind the dashboard when changing modes or temperature
  • Heating / Cooling not working properly. Often permanantly on heat or cold.

Tools Required

  • Trim Removal Tools
  • Screwdrivers

Parts Required

System Overview

There are 4 HVAC actuators in the system, each one is identical

  1. Air Recirculation Door Actuator – Located above the blower fan and controls the recirculation function.
  2. Floor Vents – Upper left side of centre console (Passenger Side)
  3. Heat/Cool – Lower left side of centre console. Uses interconnecting levers to control the butterfly valve inside the heater box
  4. Face Vents – Upper right side of centre console (Drivers Side)

How To Identify The Faulty Actuator

Multiple actuators can be found on both the left and right sides of the dashboard. The same actuator units are used regardless of its purpose. Let’s go through some troubleshooting steps below:

  1. Attempt a HVAC System Relearn
    • It’s possible that your actuators are not actually faulty but have ‘forgotten’ which position they are in. The relearn process runs all actuators for 10-15 seconds, allowing them to calibrate their positions.
    • To do this first close your doors and turn the radio off. You’ll need to listen to the motors and they’re very quiet.
    • Turn the Ignition to ‘on’ but do not start the car. Press and hold the rear demister button until you hear the actuators moving. After 10-15 seconds the actuators will stop and the system will be calibrated. Test the air conditioner system and check if your problem still exists. Be sure to cycle through each mode and heat / cool.
    • If the problem still exists or you heard loud clicking noises during this process, its very likely that an actuator is faulty. Proceed to the next step.
  2. Identifying the Faulty Actuator
    • If you heard loud clicking noises during the relearn process this will help with identification. Run the relearn again and listen for the clicking. Is it on the passenger or drivers side? Listen around the footwell area on both sides and you should be able to determine where it was louder. We now need to access that actuator.
    • If no clicking was heard and you still suspect the actuator is at fault, visual identification may be required to see if the motor and HVAC arms are moving when the relearn is in progress. This will involve trim removal from the drivers and/or passenger side of the vehicle. We’ll run through this process below.
    • Note: There is an electrical interlock between the AIR RECIRC function and the HOT/COLD mixing function. If the system detects a malfunction in the AIR RECIRC, the HOT/COLD mixing actuator is disabled. This fault is indicated by the LED on the RECIRC button blinking.When you run “relearn, if the HOT/COLD actuator is not moving, this does not necessarily indicate that the actuator has failed. It might be that the RECIRC system has failed, and the interlock has disabled the HOT/COLD mixing actuator. Confirmation of the fault is indicated by the blinking LED on the RECIRC button.
    • It is possible to have multiple actuators fail! Keep this in mind when performing your assessment.

Drivers Side Actuator

The drivers side actuator which controls the air directions between feet, face, demister is usually the faulty unit. It is often identified as the air conditioner being ‘stuck’ on feet or demister modes. The process below outlines the actuator replacement procedure.

Step 1

Using a trim removal tool, pop off the side trim piece. There are three clips, one on each corner.

Step 2

  • Wedge your fingers behind the lower section of the trim and firmly pull upwards as shown by the red arrows.
  • With the bottom clips released use a gentle hinging and pulling motion to release the top clips on both sides of the steering wheel. Pull away as shown by the orange arrows.
  • Be careful releasing the clips as the trim will drop downwards. It is quiet heavy.

Step 3

As the trim is released you will need to unplug the headlight switch. Push on the clip and unplug.

Step 4

Unscrew the OBD port as circled and pull downwards on the kick panel trim. There are approximately 5 clips holding this trim in place.

Step 5

Remove the air conditioner ducting which is held in place by two screws.

Step 6

You’ll now need to locate the actuator. Look up beside the headunit and high in the dashboard your will see the actuator as pictured.

To verify the actuator is faulty, run the relearn process as described previously. If you feel or hear the actuator clicking, or the HVAC arms are not moving, the actuator is probably at fault and will need to be replaced.

Step 7

Replacing the actuator is a very difficult process due to the location in the vehicle. There are two screws (Red circles) holding the actuator in place, and one alignment pin (Green circle) to ensure the actuator is in the correct position. There is also a green wiring plug you will need to disconnect.

The bottom screw is relatively easy to access with a small stubby screwdriver or a ratcheting screwdriver set.

The top screw is extremely difficult to remove as there is limited space to operate. You may find yourself lying upside down in the footwell and painstakingly turning the screw millimetre by millimetre.

Once both screws are removed the motor will simply pull off from the HVAC arm. The HVAC arm may fall off, so take note of its orientation and position to simplify reinstallation.

Step 8

The replacement actuator (Which you can purchase directly through us at AutoInstruct – We’d appreciate the support!) can now be installed into the vehicle.

Firstly reinstall any HVAC arms that may have fallen loose, then slide the arm onto the actuator – It can be in any position. Next place the actuator onto the alignment pin and begin to install the lower screw.

Commence installation of the upper screw, checking alignment and position of the actuator and HVAC arms.

Step 9

Once both screws are tightened, connect the wiring harness and perform a HVAC relearn. You should now see the actuator moving smoothly without any clicking noises. When the relearn is complete, test operation between feet, face and demister. Keep in mind we have removed the ducting on the drivers feet!


After confirming correct operation, reinstall the air conditioner ducting and lower dash trim pieces. Reattach the OBD connector. You’ve now finished!

Passenger Side Actuator

Step 1

Remove the kick panel below the glove box. This is held in place by five clips.

Step 2

Remove the two screws which are now visible.

Step 3

Remove the five remaining screws. The far left and right screws are hidden behind small covers.

Step 4

The glovebox will now be loose. simply pull outwards and disconnect the boot release plug and loom.

Step 5

Pull outwards and down the side trim piece. It will unclip.

Step 6

Now we can see the passenger side actuator.

To verify the actuator is faulty, run the relearn process as described previously. If you feel or hear the actuator clicking, or the HVAC arms are not moving, the actuator is probably at fault and will need to be replaced.

Step 7

Remove the faulty actuator by unplugging the electrical connector, unscrewing the two screws and pulling the drive gear off the HVAC arm. This actuator is much easier to access compared to the drivers side.

Replace the actuator with a new unit. Screw into place and reconnect the wiring loom.

Step 8

Once both screws are tightened, connect the wiring harness and perform a HVAC relearn. You should now see the actuator moving smoothly without any clicking noises. When the relearn is complete, test operation between feet, face and demister. Keep in mind we have removed the ducting on the passengers feet!


After confirming correct operation, reinstall the air conditioner ducting, side trims and glovebox. Don’t forget to reconnect the boot release switch.

      Hi Harry, have you ever seen this causing any problems to the power windows? I have had problems with my power windows of late sometimes they work but as time goes on it’s getting longer each time. I have replaced the switch and window control module and it still hasn’t fixed the problem but I was just told this could be the problem.

  1. Bryan Markham says:

    great layout & step by step pics that really does help although yeh was frustrating putting the damn thing back in (driverside) lol. thanx heaps 😉

  2. Sean says:

    Hi guys so i have a 2008 ve ssv ute. The aircon is stuck on demister. And blowing cold air on drivers side and hot air passenger side. Ive done the relearn and nothing seems to fix the problem. I just followed ur steps in pulling it all apart even thou i dont have a replacement actuator atm. I just wanted to see whats going on, theres loud clicking coming from the drivers side put the arms do seem to move. I did the same on the passenger side and theres nothing moving at all…so do i replace the passengers side Actuator?

    • Staff @ AutoInstruct says:

      Hey, even though the arms are moving, the clicking actuator would be faulty. They should not click at all, even during a relearn. I’m unsure about the passenger side, but drivers side seems faulty.

    • John says:

      Hi Sean,
      I’m having the exact same problem as you had.
      What was the cause? When you replaced the drivers side clicking actuator did the passenger side end up moving/working?
      Regards John

  3. les west says:

    thanks guys now have working a/c thanks for the easy to follow instructions did’nt have to wait long for the actuator either……well done guy’s

  4. Storm says:

    Hi guys i have an 08 statesman and sometimes im not getting and airflow from front face and both passenger side vents. You can hear the fan going but nothing is being let through. Would this be the same actuator? Mechanic told me it was a directional actuator? Also quoated me over 600 just in labour. It will work after i turn the car off and on a couple of times.

    • Staff @ AutoInstruct says:

      Hello, I believe this may be the drivers side actuator. Try the ‘relearn’ procedure as indicated in the article, and listen for clicking noises. If the actuator clicks it is definitely faulty.

  5. cameron says:

    I have a ve calais air conditioner working but will stay on face but after car is off and when get back in the car the air con blows on screen and i can’t change it back

    • Staff @ AutoInstruct says:

      Hi Cameron, It sounds like the actuator could be having issues. Please attempt the relearn procedure as indicated in the guide.

  6. Matt says:

    Hi guy’s I’ve replaced the actuator on the passenger side and it still doesn’t work. The unite is blowing hot air on the passenger side and ac on the drivers . Any ideas would be good thanks matt

    • Staff @ AutoInstruct says:

      Hey Matt, did you perform a relearn after replacing the actuator? Have you inspected the drivers side actuator?

  7. Matt says:

    The Actuators all seem to be operating fine except when this one on the passenger side is fit in to place it only moves the down position and when I disconnect it then with only the wire contact connected it operates to the three different places.

    Please help Matt

    • Staff @ AutoInstruct says:

      Hi Matt, Did you reinstall the white plastic arms into the correct position? Try re-install and perform a relearn again. I’d also inspect the drivers side for correct movement, it could be related.

  8. Emma says:

    Every time I start up my car there is a knock behind the dash, I’m presuming its a faulty actuator, I’ve done the HVAC relearn and nothing has changed. Can you please let me know if it is worth changing the actuators?

    • Staff @ AutoInstruct says:

      Hi Emma, if you’re hearing clicking noises behind the dashboard and the air temperatures / direction are behaving odd, it is definitely time to change the actuator. Try and work out which actuator is faulty by listening closely to the clicking sounds, and finding the source.

  9. Robert says:

    Fantastic article to do it yourself. Everithing in detail and with photos. Great job. Also i sugest the palm screwdriver for top screw on driver side actuator. Cuts the time in half.

  10. Patrick says:

    Hi I have a 2011 VE Berlina Series 2 with Dual Zone Climate Control.
    My wife drove a small distance, go out, and when she returned and started the car, the A/C fan was on max (20). She has tried everything to reduce the fan speed to no avail.
    Any suggestions?

    • Staff @ AutoInstruct says:

      Hi Patrick,

      Sometimes this is an issue with the front facia of the headunit, and the connections become loose. Jump in the car and push firmly all over the trim that surrounds the HVAC and radio buttons. Then try adjust the fan speed again.

    • Staff @ AutoInstruct says:

      Hi Richard,

      Rattles are very hard to diagnose as it could be anything – Best bet is to begin disassembly and try to find the source.

  11. Adam says:

    I have a 2007 Ve sv6 appears heater is stuck on heat, won’t switch to cool at all. And without fan I’m still pushes out hot hot air any idea how to fix?

  12. Adam says:

    Air con compressor was first to let go.
    Replaced with low km second hand unit. New seals. Regassed. Worked good for 20 mins now not working.
    Have had gas level checked and it’s fine, have no issues with fan speeds. Air vent directions etc.
    just on cool or in middle between hot an cold it’s pushing out very hot air,
    Any help would be great cheers

    • Staff @ AutoInstruct says:

      Hi Adam,
      This sounds like a complicated issue. It could be the air-mix actuator which controls the delivery of hot or cold air. Have you tried the relearn procedure? Do you hear clicking noises?

  13. Adam says:

    It’s seems to me that it’s not switching from heat to cool, what side is that actuator and what’s a way of testing I want to fix the car asap as Adelaide has a heat wave and if faulty I’ll buy some off u guys

    • Staff @ AutoInstruct says:

      Hi Adam,
      We’re not sure exactly what each actuator controls, and are currently trying to seek this information. They tend to all work in tandem. When one dies, the whole system behaves odd. You’ll have to inspect each actuator for movement and see if one appears stuck or not moving correctly.

  14. Adam says:

    If I were to buy actuators from you, how long it take to post and for me to receive I’m located in south Australia post code 5090

  15. Adam says:

    I removed glovebox. Checked the actuator and with car unstarted the actuator moves as it should start car and goes straight to heat, remove actuator and works as it should so guessing it’s stuffed
    I can confirm lower actuator on left side is for heating/cooling 😉

  16. Steve says:

    I have a after market alpine head unit with touch screen hvac in my 08 r8 … i can feel the ac come out of the feet but when i switch mode to face light breeze comes out of the top vents could this be actuator drivers side and if it is .. is it the top one or bottom on
    Cheers thank you

    • Staff @ AutoInstruct says:

      Hi Steve, It could be the actuator, or actually a characteristic of the HVAC system. If it is an actuator at fault, it will likely be the drivers side at the top as seen in Step 6.

      • Luke says:

        I have an aftermarket alpine headunit eith the touchscreem aircon. I have just replaced drivers side actuator and still only have air blowing out of the windscreen vents. Arms are moving and there is no clicking. Thought maybe HVAC control module but changed that too and still the same thing.

  17. Glenn O'Rourke says:

    Hi My 2008 WM Caprice has the heat only on Drivers side problem. I have done the relearn but not fixed.

    I have just ordered a new Actuator from you but the above instructions show the direction Actuator, not the Heat/cool one.

    Where is the heat/cool actuator located in relation to the direction one, please?

    Thanks in advance

    • Staff @ AutoInstruct says:

      Hello, Based on the feedback from customers it appears the “Passenger Side Actuator” is for heat / cool on both sides. We’re trying to confirm this with Holden at the moment.

      • Glenn O'Rourke says:

        It is a 2008 Caprice with dual climate control. Passenger Side is working fine but Driver’s side is constant Heat.


        • Staff @ AutoInstruct says:

          Hi Glenn – We’re not exactly sure at this stage. Can you hear the clicking sounds? Perhaps visually inspect the units for movement when changing temperature

          • Glenn O'Rourke says:

            no clicking sounds. the top and bottom Actuators are both moving, the centre one does not have the long white cog and you can’t see anything on the other side as it appears to be connected straight to the box its screwed to. I assume this is the one that needs replacing. It looks the same other than no white cog

          • Staff @ AutoInstruct says:

            Hi Glenn, This is difficult for us to diagnose. I’m also not familiar with the actuator you mentioned – All of ours have the white cog on both sides.

  18. Mark says:

    Really helpful site – awesome level of detail and clarify on the instructions. Ordered a drivers side actuator from these guys and problem sorted – now have air flow to the face vents. Hope it lasts a while as I don’t want to have to do that again in a hurry.

  19. Daniel says:

    Hi AI,have you ever seen this causing any problems to the power windows? I have had problems with my power windows of late sometimes they work but as time goes on it’s getting longer each time. I have replaced the switch and window control module and it still hasn’t fixed the problem but I was just told this could be the problem.

  20. John F. says:

    2010 E2 GTS – lost face vents, found this web site – tried the diagnostics – determined the fault as the d/s vent actuator – ordered 2 actuators (to prevent the other side failing :). Items arrived within 5 working days and fitted last weekend – took approx. 20 minutes being a 1st timer, the instructions were spot on and easy to follow. issue solved! thanks to Autoinstruct and the team. LEGENDS! BTW: job made very easy with the use of a $3.00 screw driver set containing one of the smallest stumpy phillips drivers I have seen from the local $2 shop.

  21. Arthur Coombes says:

    Hello, is this the same process for the VN Commodore Sedan as the air-conditioning works fine but the main cabin vent closes once the cold air starts to flow out into the vehicle?

  22. Richard says:

    Hi there what fantastic instructions you have provided
    I have a problem with the air conditioning/hvac system clicking sounds left hand foot well Ve commodore.
    I followed your instructions removing glovebox and hvac actuator.
    I preformed a relearn once actuator was removed.
    The clicking noise is still there I’m assuming this actuator is not at fault. Please confirm if the arms are connected to another just above and if so do you sell these and how on earth do you get to it??
    Would you be able to provide instructions as to how to replace this
    Cheers Richard

    • Staff @ AutoInstruct says:

      Hi Richard, When you said the clicking noise was still there, was this after you disconnected the wires from the original actuator?

  23. Drew says:

    Air-conditioning worked well on all settings besides the foot well, did the relearn and now it’s only pumping hot air on the windscreen regardless of what I select. Any idea why that would be? It seems like the relearn has made my issue worse. 2010 s1 VE SS

    • Staff @ AutoInstruct says:

      Hi Drew, This generally means the drivers side actuator is faulty. Our tutorial covers this replacement, and we welcome your purchase through our online store.

  24. Jake says:

    Hey Team.

    Just wanted to say a big thank you, your guide helped me actually pin point the problem and the product that i purchased from you works perfectly now. The guide was easy to follow and allowed me to do it with ease, apart from actually installing the new unit haha, it was a bit of a pain considering the position and how tight it was

    so thanks heaps.
    Jake s

  25. Simon says:

    Great post! Just replaced the driver’s side actuator in my ’08 clubsport. That top screw was a little awkward to get to, but all fixed. Air con is working great again. Cheers.

  26. Jamie says:

    Hopefully the actuator is my problem too. I can push and hold the fan speed + up to 20 and everything seems to be fine but as soon as i let go it starts going down to 00 by itself. Ve s2 r8

    • Staff @ AutoInstruct says:

      Hi Jamie,
      This is unlikely to be the actuator, but rather a problem with the ‘Fan -‘ button. Try push firmly around the entire HVAC control buttons and fascia to try and fix the loose connection.

  27. Jay Browne says:


    I have a 2007 VE Lumina & the A/C control button will not illuminate (turn on) I tried an actuator reset & can here the actuator clicking on the RH side, will this cause the A/C on/off button not to operate? It was re-gassed recently & worked fine then suddenly no on/off, fan speed works fine, tried another fascia panel still the same, any Idea’s? how much for the actuators ?

    • Staff @ AutoInstruct says:

      Hello, The actuators are unlike to be related to your A/C issue. This sounds like a problem with the control board, or A/C Compressor. The actuators can be purchased via the link on this guide.

  28. Rick says:

    Do you have similar instructions for a Holden Cruze 2010 to relearn for the acruators, and how to check/replace the HVAC module?

  29. Rusty says:

    I have this exact same problem, it seems that at some stage, every VE is going to succumb to this problem. I am in the market for at least one actuator, not sure if it’s driver or passenger side yet, as before reading this article, I had put it into the “too hard basket” Where & how much can we get the new & improved actuator.
    Thank you kindly, Insano 6L.
    PS, Are the drivers & passenger side actuators both the same ?

    • Nick @ AutoInstruct says:

      Thank you for the feedback Rusty, you’re correct its not too difficult once you see how its done. Both drivers & passenger side actuators are the same, you’re correct.

  30. Insano6l says:

    PSS, would you suggest to replace both actuators ? It seems to me that if one crappy genuine Holden actuator has malfunctioned, its more than likely if the other is identical, it will also eventually Fail ??

    • Nick @ AutoInstruct says:

      We would recommend doing both sides at once, I’m sure you can tell by now that these do inevitably fail so it can be better to do it all in one afternoon.

  31. Rich says:

    Yep worked a treat !! Not wrong about that top screw :/ but all good now 🙂 on closer inspection when I popped the old unit apart the small cog had broken inside

  32. chris brown says:

    ve e3 r8, air con cold on drivers side, warm /cool air passenger side and back seat vent when system on cold, switch to heat and get the opposite, drivers hot obviously, passenger and rear vents are cold sort of, had system checked for leaks etc . all ok & gas ok.
    thinking actuators are the issue,
    would it be best to just replace all of them while dash is apart or do they not fail that often?
    Car is a 2012 model but only 55k on it.

    • Staff @ AutoInstruct says:

      Hi Chris, It does sound like the actuators. Have you tried the re-learn test? Later model VEs like yours have a revised actuator that should not fail. It is probably a one-off rather than all of them.

      • Chris Brown says:

        Yes have tried the re learn process, no success, they do not click as such but you can hear the passenger side more than the drivers side in the learn mode.
        Will let you know, have an air con tech having a look today. I don’t the patients to do myself.

  33. Craig says:

    Great post, very clear instructions with accompanying photos, well done guys.

    I have a 2006 ve ssv. Compressor is turning on when selecting air con although does not come through vents unless you are moving at speed. The fan is not blowing. I took the fan out and tested and it spun with an external 12v power source. Is it possible that a faulty actuator could be the culprit? I have tried the re learn test and actuators seem to be activating and no clicking sounds.

    • Staff @ AutoInstruct says:

      Hi Craig, a faulty actuator is unlikely to cause the issue you described. I would suggest an issue with the HVAC Controller, and the 12V output which controls the fans.

  34. Brent says:

    Excellent instructions. There were a couple of screws missing in instructions cant remember which step though. I had 2012 series2 and replaced drivers side. I was having to continually do the relearn each time in the car which i got sick of doing. Found using a screw driver bit in a small socket wrench was way to get difficult screw out. Wouldnt have been able to get it out otherwise. Old actuator had vent in a different position which made alignment a bit tricky when fitting new actuator. All good now. Thanks.

  35. Joe says:

    I am having issues with my 2009 SS VE sportswagon when I put the aircon on or heater and change the direction of air flow to the floor vent there is no air it just comes out the front? Can anyone tell me what the issue is, is it the Actuator? If not any ideas how to fix this problem.

    • Staff @ AutoInstruct says:

      Hi Joe, That definitely sounds like the actuator. Try run through the re-learn procedure and listen for clicking noises. That will identify the actuator at fault.

  36. Bruce says:

    Hi, I have a 2009 VE Commodore Sedan. The Re-circulation was not working and I carried out the RE-Learning procedure. Now there is only Hot Air blowing even when the cold air is selected. Any Ideas please? Is the Re-circulation and Temperature controlled by the same actuator?

    • Staff @ AutoInstruct says:

      Hello, these are different actuators, and I have never seen a faulty recirculation door before. Not sure how to fix that unfortunately.

      • BRUCE says:

        Thanks for that! I removed the glovebox and found two actuators, one in the position indicated in your diagram (that is not functioning) and one above that is functioning. I will replace the faulty actuator (it’s probably the Hot / Cold control) and chase down the re-circulation door functionality!

        • Luke says:

          Hey mate I’m going through the same problem. I have changed the hot and cold Actuator, the recirculation actuator, even tried changing the radio and climate control modual with my mates ones and still can’t get the arm to move off hot unless I manually move it. Did you end up finding the problem with yours

  37. Matt says:

    Hi Team,
    Some great info here. I recently had my trusty local repairer change the faulty / broken actuator on the drivers side for air vent control on my 2010 VE Omega dual fuel ute. (217000klms).
    I am now having an issue with the HVAC fan intermittently working. It either works Ok with variable speed control or absolutely nothing. All other modes function as required. Last time it did spin I did notice that it was a bit noisier than normal, mainly at higher speeds.
    Any ideas on what could be the problem?

    • Staff @ AutoInstruct says:

      Hi Matt, It could be the bearings in the fan that have failed. There is also a common issue with a loose connection on the HVAC Control Facia. Try push firmly on the trim around the HVAC buttons and see if the fan speed control works again.

      • Matt says:

        Hi Team,
        Have pushed firmly all around the HVAC facia panel with no luck getting the fan to run.
        I have selected all modes, stopped and started the vehicle and checked the under bonnet fuses still with no response.
        Would it be wise to check for voltage at the fan motor connection, if so how do I access this?


        • Staff @ AutoInstruct says:

          Hi Matt, The fan motor is located directly behind the glovebox. If you remove the glovebox you should see a cylindrical shaped end with connectors.

          • Matt says:

            No problem, checked supply voltage at connector, removed the fan to clean and service – all sorted

          • Staff @ AutoInstruct says:

            Hi Matt, awesome outcome in the meantime! Thanks for posting the steps, we might add them to this guide.

  38. Matt says:

    Update: Followed the instructions to remove glove box , yay – fan blower is right in front.
    Checked for variable voltage at plug connection, showing .084vdc on minimum to 12.55vdc on high speed fan selection through the dial.
    Removed 3 screws + 2 cable loom retainers to remove the fan unit from the blower assembly.
    Removed service cover from fan unit to expose internal brushes / armature etc. Bearings at this stage seem fine and smooth.
    Spun the unit and blew out a lot of carbon dust with compressed air followed by a squirt of electrical cleaner. Continued to blow out any excess before hooking up the plug connection and retrying operation – all OK.
    Reinstalled fan unit and reassembled glove box etc. Retried full function test of HVAC – all OK.
    I think a new fan unit will be needed in the not to distant future……

  39. Mick Tattoli says:

    Ve commodore. I have done what u said and no more clicking noise BUT now i only have heating. No air con. Only blows hot air on heating and cooling. Why?

    • Staff @ AutoInstruct says:

      Hi, That would mean the actuator is faulty and needs to be replaced. Generally if you attempt a re-learn again it will make the clicking noises, pointing you towards the faulty actuator.

  40. Kris says:

    Hi team! Awesome guide made it so easy to replace both actuators. However after replacing both i still dont have hot air. Did the relearn and it cycled fine but with the actuator installed or just held in my hand and plugged in nothing happens as i use the temp dial. Any ideas on a solution to this issue?

    I would urge people with the Directional issue (unable to blow on feet etc…) to avoid trying the calibration. I did this in the first instance and it defaults the unit to front demist on heat only. You can no longer change direction of air or hot/cold. Air-con becomes useless also.

    It seems that running the calibration when the drivers side actuator is faulty, then stuffs up the micro controller on the passenger side. I verified this by running the calibration while watching the passenger side actuator. It moves fine with the calibration but does nothing with normal use e.g. switching hot/cold.

    My advice is to either live with having no air on your feet, or simply replace the drivers side actuator. DO NOT RUN THIS CALIBRATION.

    Interesting that AI are not aware of this ‘trigger’. It renders your unit pretty much useless. Anyway great pictorial tutorial 🙂

      Hi Mike, The system has defaulted to front demister on heat as a precaution for driver safety. This is because it has been unable to correctly read the actuator limits, usually due to one being faulty, which simply needs to be replaced. If no actuator is faulty, the systems should correctly re-calibrate.

    Hi team I am having issue with the driver side aircon only blowing cold, passenger side will blow hot/cold, tried to rest in all settings, going on the diagram and reading comments would it be actuator 3 hot/cold or driver side ?. i can’t hear clicking but there is some noise when moving.

      Hello, It can be hard to tell sometimes. Best bet is to visually inspect the actuators for movement when changing modes. Other than that, likely sounding like the drivers side actuator.

    great thread i swapped out drivers side acuator now pefrect recirc one is fine can feel move passenger side floor vent one is all good but unfortunatley heat cold isnt working the acuator turns in my hand and can also turn the levers either direction if i slip it into the cog when i do the auto learn procedure but then it will stay in what ever mode its in hot or cold the re learn is no good if actuator is all conected it wont move until i undoe it all and its just hanging there its not a new actuator im guessing the motor inside dosnt have the guts to push it ?i guess they wear out strength wise? i have tryed 3 seperate actuators from another vestill the same problem? thankyou for any help

    • Staff @ AutoInstruct says:

      Hi Shane, It could be an issue with the flaps inside the system. They can sometimes break or become jammed, and the actuators are not powerful enough to move them.

  44. Joel says:

    Hi. I have a VE Series 2 SSV. I have a problem where the touch screen blacks out momentarily cutting out the radio and air conditioner/fan. The radio comes back on within a few seconds but the a/c and fan can take up to 5 minutes to come back. I have had it suggested that I may have a shorted actuator but I’ve run the relearn procedure and can’t seem to replicate the problem. Any suggestions would be welcomed.

    • Staff @ AutoInstruct says:

      Hello, We’ve never heard of this before, I would be surprised if the actuator was at fault. Sounds like a bigger electrical issue.

  45. Alex says:

    Hi there ,,I have a VE V6 Omega 2008 model ..i have a problem with something under dash board ,,every time i start the car i hear clicking noise under dash board ..i went to holden & they say the actuator problem ..but every thing is working fine except the noise only when i start the car ..the noise is just in the center of the car ..under dash board . Holden were asking me for $250 to fix the noise problem ..any idea how to fix that problem …Thank you ..Alex

    • Staff @ AutoInstruct says:

      It sounds like an actuator, they can cycle when starting the vehicle. Please follow our tutorial steps to identify and replace the faulty actuator.

    Hi AI Team,

    Just a quick note of appreciation, this is an outstanding site and has been extremely helpful.

    I have 2011 VE SSV Redline Series 2 ute and for a little while have had the aircon stuck on face only. I had consoled myself that before next summer I would have to take it back to the local Holden dealership with the expectation of having to part with a large sum of cash to repair. In desperation I checked the internet to see if anyone had the same problem and came across your website. As suggested I ran the “relearn” process which unfortunately pushed the settings to “Demist” only with hot on the passenger side and cold on the drivers side. But, it did alert me to the loud clicking behind the dash. Armed with your tremendous instructions I took the gamble an ordered a couple of actuators which arrive in three business days (thanks guys). It took me just over an hour and the loss of some skin off my knuckles to replace the driver side actuator. Yeah the top screw is a cow both coming out and going back in. My HVAC system is now back up and operating as designed. Overall it was well worth the effort even though I didn’t need to replace the passenger sid, at least I now have a spare if it ever happens again. I can’t thank you guys enough.

  47. Robert says:

    Hi, I have a 2007 VE and when I turn the air con on, the light on the button comes on but the compressor doesn’t engage, it’s like an electrical fault. Could any of the HVAC components be causing this. Thanks.

    • Staff @ AutoInstruct says:

      Hi Robert, Best to see an A/C specialist for this issue. Typically there is a faulty sensor which is not allowing the compressor clutch to engage.

  48. Colin Creaser says:

    Have had problem with air con stuck on wind screen. Have tried relearn countless times and have heard no clicking. Figured after reading above that it had to be actuator on drivers side and ordered a new one from you. Turned up in a few days (N.T.) Had problems keeping my glasses on, holding torch in position, and after totally stuffing my back thought this is a bloody mugs game when your in your mid 60s. However i don’t like to give up and managed to get it in, made sure the arms were moving, test it and no difference. Must be the other side i decided, take it all apart, check it with relearn and moves no worries. So i’m back to where i started. Any ideas?

    • Staff @ AutoInstruct says:

      Hi Colin, It’s interesting that the arms are moving yet the airflow does not change at all – Is that correct? It could be that the internal HVAC doors are jammed or damaged.

  49. Colin says:

    Yes, the arms on the actuators on both sides are moving, and the airflow is still stuck on the front windscreen. The one i fitted on the drivers side is the one i bought from your company recently. Are you saying that the passenger side actuator is faulty even though its moving?

    • Staff @ AutoInstruct says:

      Hi Colin, it can be hard for us to determine the issue remotely. It could be one of the other actuators in the system causing issues. I would re-check the drivers side actuator fitment and arms.

  50. Mark louth says:

    Hi I have a Ve commodore , when the car engine is off and set to face the air blows through front face vents fine, but when I turn the key again and start engine the face vents stop blowing and it sounds like the air is coming out somewhere near the windscreen , but nothing through the face vents. Then if I start flicking through different modes like demister,foot, face, demister , foot , face thensometimes I can get it to come through the face vents again. I can’t hear no clicking. Does this sound like the actuator

    • Staff @ AutoInstruct says:

      Hi Mark, It could be a sensor or AC Compressor issues thats making the system behave in an odd manner, especially considering it only occurs when the engine is running.

  51. Wayne O says:

    Hi Guys. I have done the above relearn and didn’t notice any clicking sound. But still don’t have and heat coming thru. Any suggestions would be much appreciated.

  52. John Adams says:

    Hi, with thanks to your awesome step by step guide, plus purchasing the actuator through your site, I was able to get our vents all working properly again. Your guide provides very clear steps for removing/replacing the faulty part.

    Also just out of interest to others after reading some of the comments above, to start our air con and heater both worked, but no air came out on our feet. After reading this site I did a reset and then we only got hot air blowing with the red light flashing to indicate a fault. We took the car into the local mechanic and he did a computer reset which allowed the air con only to work (which in this climate was a better option than heat only). We then ordered the drivers side actuator and all seems to be working fine now. Cheers, John

  53. David McGowen says:

    “Re-learning” the system actually made it worse! I had an issue with the RH heater not working sometimes and after “re-learning” nothing works!! Temp control; face, floor or demise vents all closed. Fan works to blow cold air out of the seams!!

  54. Christopher Wakerley - Palmer says:

    Hey guys
    I have a 2009 Ve commodore sedan
    And it is stuck on the front window setting and stuck on heating won’t cool or change
    Any ideas ?

  55. Joe says:

    I’ve lost the original position of the drivers side arm as it fell off during removal. Do you have a pic or diagram of how it should go on? Thanks.

  56. Nigel says:

    Hi. I have a VE 09 SS ute and the recirculate vent has been closed for 12 months and no longer makes the clacking sound on start up.
    I tried the relearn, and now the heater is stuck on hot.
    Does this mean the recirc. Actuator is buggered and electrically stopped the cold air? If so, do you have instructions to get above the blower fan ?
    Any help would be appreciated.

    • Nigel says:

      Well, I pulled the glovebox out and replaced the actuator on the side of the fan. What a bastard.
      ADVICE always check the actuators action by pressing the relearn before pulling anything out. You can see which actuator is turning before you start. It appeared the air mixer one (top) wasn’t working. I moved the vent linkage to the open setting and refit. I got the cool a/c going again.
      Still no recirc that I was trying to fix.

  57. Fahad says:

    Hi AI Team,

    A very educational threat related to VE Commodore HVAC System. I am not sure if you will be able to direct me in the right direction to rectify my SS air con.

    So it started last Saturday, I started the air – con first time after winter and I hear a hissing noise with no cold air coming out of the went. Few attempts later after switching the car off and restarting the AC light does not turns on and no hissing noise could be heard and the vents will only blow hot air.

    Could this be an actuator issue? Refrigerant leakage? Or a compressor issue?

    Your help would be really appreciated.

    • Staff @ AutoInstruct says:

      Hello, It sounds like a seal has gone and refrigerant has leaked out. This is why it’s crucial to use your A/C all year round, even in winter as it keeps the system lubricated.

      • Fahad says:

        Thank you Team AI for coming back to my question. I hope you would not mind me asking another question.

        So went to my local Mechanic and he tried to check leaks in the system unfortunately could not find one. He hooked a R134 refrigerant cylinder to the system and tried to give a system a little bit of gas just to make sure if the Compressor is engaging or not, please note the system was not fully re-gased. In the mean while all the fuses and connections were checked to rule out power issues. Unfortunately th A/C button does bot lit after this.

        My question is does the needs to be fully re-gased for the A/C button to engage the compressor or is there an issue with the button it self.

        The car is still at his place for the last few days and we are still unable to determine a possible cause which is stopping the A/C to work.

        Would really appreciate if you could respond to this.

        • Staff @ AutoInstruct says:

          Hello, Honestly I am unsure. It sounds like there could be an issue with the HVAC system, and a sensor somewhere (Such as a pressure sensor)

  58. Phil says:

    Hi, Have a 2010 VE Calais. Air con fan stopped blowing onto passenger & drivers feet, but front & side vents were ok. I done a re-learn, it then stopped blowing through all vents, except windscreen demister. It still blows hot & cold though, but demister vents only. The relearn sounds like a winding sound though, more so clicking.
    If I need a new actuator, will it be the drivers side, as the noise is from the centre vents when relearn?

  59. Mick says:

    Hi, I have a MY09.5 SSV Commodore. I didn’t have any problems with my HVAC system, but upon hearing of the relearn procedure, I stupidly decided to try it. No clicking noises were heard. And now all of a sudden I have the only blowing hot air out of the passenger and rear vent problem. So I have to agree with some of the above posts, do not try this. It seams running this internal program can corrupt the system somehow. I have read on other forums that disconnecting the battery overnight has fixed this. So before I start pulling things apart I am trying this tonight and will update you guys tomorrow how this goes. I also have one of the cheap OBDII Bluetooth scanners and it did not show any codes.

    • Staff @ AutoInstruct says:

      Hi Mick, The relearn will only cause issues if something is truely wrong with the system – E.g a broken actuator (Clicking noises are not always audible). The re-learn looks for the endpoints of the actuators, and runs into issues if the actuator is faulty. The cheap OBDII Scanner will not display HVAC error codes, only powertrain.

      • Mick says:

        I’ve recently replaced my cabin filter, when I did this I noticed there was a dome like cover over the blower motor. So this morning after reconnecting the battery and still having the issue, I thought this would be the easiest thing to check, assuming this domed door is what controls the re-circulation I checked to see if it moved when going from fresh air to recirculate. It did not. If therefore this does control the recirculate function, should I be seeing the led in the recirculate button blinking as you described under identifying the fault? Because it is not flashing. And if the actuator for this door is faulty how do I access it to replace it?

        • Staff @ AutoInstruct says:

          It’s difficult to diagnose this remotely because any number of issues could lead to a certain component not working or operating. E.g the LED may not flash. We don’t have a guide for that actuator, however it’s quite hard to access as it sits on top of the blower motor, behind the glovebox.

  60. Mick says:

    Hi Guys, it turns out the problem was the pivot on the re-circulation door, which was broken (a common occurrence apparently). Where the actuator engages with the pivot is a weak point. So when I did the relearn it detected this and, in turn disabled the mixer door. So anyone who has done the relearn and then has the passenger side and rear vents blowing hot air, this could very well be the problem. The door can be replaced through the engine bay underneath the plenum cover. It is not however an easy job and nearly cost me my sanity lol. You can order a new recirc door through your holden dealer. The part number is 92246499.
