Headlight grinding

this motor is sealed:

All the stops are internal, from what I remember. There are only a few adjustments in the outside, it sounds like the bevel gear has worn, and the worm gear slips a bit after the linkage hits the stops.

Maybe time for a new one, unless parts are available.

Time to PING the man: bigfig, he's the resident genius on parts and subassemblies.

I hope this helps?

The balls inside the motor have finally given and now become a fine dust. You'll need to get new internal bumpers. I bought them here:

See other post by Bruce. This is a common problem that the aftermarket, not the OEM has fixed with inguenity.

As I recall, GM will make you buy the whole ball of wax when the old parts can easily be replaced/repaired.
