W163 air actuator motor
After stripping the airbag out and removing the motor (easy job, no dash removal required). The link arm has stripped on the motor shaft, this is due to the fact that on coldest setting the motor turns constantly one way, turn the dial up one click and the motor turns the opposite direction constantly! I tried a replacement motor and it is the same. I have not located any sensors that control the motor apart from the climate control unit. Any ideas, I love this motor
You may be able to put an eyeball on it with a mirror or you can pull the radio and easily see it.
