I know this is a well covered topic but i cant find any post's with the exact same problem. My c class had the steeper motor linkages fixed about 4 or so months ago and then about three weeks ago the sound came back but this time it only happens when it is cold and i am starting the car in the morning. it clicks for a while then stops. i can change where the air comes from and do the motor sync with no problems or noise. any ideas or do you think the motor itself is what is wrong?
