My headlight motors work fine, but when I turn them off, the driver's side seems to be catching on something momentarily. I can't see any obstructions, so I'm wondering if you guys have any idea(s) what it may be hitting. Thanks! bb
I would bet you have the pre-87 motors. The symptoms you describe are indicative that the rubber bump stops (shock absorbers, so to speak) inside the motor have disintegrated. This will eventually lead to failure of the gears as the hard stop will strip the teeth off the gears. The bump stops fill up a space between the gear and the drive plate. When they crumble, there is about 3/4 inches of play between the drive plate and gear.
Time for a rebuild.
Self promotion---I rebuild Gen. 1 headlight motors.
Rebuild is $30 labor plus parts, plus shipping, which usually is around $15 for USPS Priority Mail with tracking. I will use any gears you specify. If you want, you can order the gears and have them shipped to me. That way there's no markup on the gears. No payment is required until the motors ship.
