Re: Power Side View Mirror Problem
So step one is to confirm that it really is the sound of a motor. I once had a continuous buzz from a mirror, and it turned out to be wasps!
Is it actually driving the mirror glass? If you push against the glass and 'jump' the gear set, does the mirror move to restore it's position?
If it is a motor, then it's getting power. But from where? First, try overriding it by working the dash switches. One might be stuck closed. Move the selector switch from left to right, and see if anything changes.
Second thought is that it might be a short in the wiring bundle that feeds into the door. Does opening or moving the door change anything? With the door open, grab and manipulate (gently) the rubber bellows that houses the wiring going from the body into the door and see if anything changes.
