Did you meassure the resistance after the cleaning? I got 4,77kohm after cleaning…

[@KeirBriscoe]

It's been awhile since I did that repair. Im sure I did measure it, but I don't remember what the resistance was. If it was out of the expected range I would have mentioned it in the video. And the actuator is still working properly.

Hi. 4.7k ohm. You can get these potentiometer for a few dollar as compared to crazy price for the actuator

Can anyone please help them, explain, what is the purpose of these motors? Because I have a problem, air does not get to the windshield, from all other holes it works fine.

[@KeirBriscoe]

The motors open and close little dampers inside the air system. If you aren't getting any air to the windshield that should be the Defrost Damper - Green- 8E1820511B. Its located on the right hand side behind the glove box. Either the motor has died or the feedback potentiate needs to be cleaned. Run a scan with VCDS and the car will give you a hint as to whats wrong.

What items are required to be removed to get this motor

[@KeirBriscoe]

Hi. Sorry for the late reply. I’ve just returned to the default world. I had to remove the glove box and that’s it. It can have differing amount of screws depending on how the car was built. Mine had Qty-9 eight mm screws. Then an electrical connector on the back.

Thanks for a useful video. I have the same issue, but no VCDS. Do you know if it will work OK if I can fix the pot contact but not reset the error code?

[@KeirBriscoe]

I'm not 100% sure, but I think that once the pot is cleaned then the actuator starts to act like normal. The code that shows up in VCDS doesn't prevent the car from trying to operate the actuator. And if my memory is correct I didn't have to clear the error. As soon as the actuator was working VCDS stopped telling me that it was having an issue.

@@KeirBriscoe Thanks for the info. I'll pull it out and take a look.

[@GaryB007]

@@KeirBriscoe Just FYI, cleaned the pot and tested. All seems good so far.

[@KeirBriscoe]

@@GaryB007 great to hear. They are remarkably simple little devices.

Do you have video on how to open dashboard to look for actuator. I wasnt getting air at the front mirror and was told i need to replace actuator on both driver and passenger seat
