Excellent work, great wright up, tried the diagnostic test just then, worked perfectly, all that was my problem also was the little plug that goes onto the actuator motor, was a bit sticky, gave it a wriggle pushed on the wires and presto, hot and cold air, all through the settings. the heater would get warmer im assuming if the engine was hotter, i was warm but not toasting haha. 32 degs.

thanks heaps guys +1

Mine is stuck on hot. :cool:

I tried wriggling the wires and such while going through the hot and cold temperatures, but the arm still doesn't move. Do you reckon it will just need replacing instead of a quick fix?

Have you got the rest of the self-diagnosis? I did step 2 and got a 22 and a 25. Do you know what this means?

Cheers

This was exactly what I was looking for :D. Last week my system stopped blowing heat despite turning the temp all the way up. Being November, yeah a lil chilly here in Canada haha. Hopefully this will help solve my issue but I do have a couple of questions.

1. I removed my a/c system so will that effect the microcomputer's self testing at all?

2. Is it possible to manually push the servo motor to the full hot position?

Thanks so much and I'll let ya know what happens.

Cheers :)

dassvass, make sure the car is in direct light or use a 60w light globe over the sunload sensor to see if that cures your error code 25. If you are in a carport or garage that will usually give the error.

Error code 22 is the interior air temp sensor. It is mounted on the surround that goes around the center console on the dash. Usually it means it's unplugged which happens if you have been in there for something else.

I've attached the relevant pages from my service manual. Hope that helps.

Thanks a heap jonn. I noticed it unplugged when I pulled the surround out, but I didn't realise it was a sensor.

Too late for my servo though, opened it up to check the soldering and the cogs came lose inside. How much do they cost to buy second hand?

Just a quick word on how it went for me, yep it's all about jiggling the harness baby haha. Servo is back working perfectly, no fault codes came up at all once I did that and ran a check.

SUPER thread and 100% helpful that's for sure. Hopefully a Mod will 'Sticky' this as it will come in handy.

Cheers all.

I have a strange one, dont know if this is related or not..

My aircon is normally very cold, so cold you normally have to turn it off.

Other day I noticed it suddenly just started blowing regular temp air.. then after about 20 min of driving I got my cold air back.

Parked the car up, got back in and air was cold.. then went to normal air about 10 min later... then within 5 minutes it went back to cold again

and has been fine since...

Just had a look at the blend door server motor since my aircon isn't cold but the rod is all the way in. When I crank the heat up to 32 the motor doesn't move out but when I pull the rod out manually it blows really hot air. So even though the motor doesn't move it's not the cause of not blowing cool air, I think it's low on gas. I tried to wriggle the wiring loom around when i have it cranked on heating and the server motor still doesn't move.

How do you do the diagnostic test on the a/c?

View the first photos in the original post. Its all explained there.

Sounds like the blend door servo motor connections are gone. You will need to pull it out. Its behind the headunit and climate control on the back wall. You will need to pull everything out to get to it haha.

Then you will need to unscrew it, pull out the little black box. Crack it open and re-solder the connector joints.

By the way what is the little fan on the outside of the radiator? Is that the condensor fan and when should that be running? Should it be running when the a/c is on or is that a aux fan for back up?

Easiest way I found to remove the module was to pull the radio bracket with the ac/heater controls out as well, and work through the hole. After you release the rod all the screws are on the top or sides of the unit, none underneath. Unclip the harness from the little jumper cable that is mounted on the top of the module, don't unclip the connection underneath until you have it out.

Jeez I feel stupid but I can't seem to work out how to unclip the road from the servo. Tried unscrewing it but it didn't seem to work and then looked over the white plastic arm to find something to unlatch but can't see anything. What's the secret? :)

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
