Need Headlight Help
The motor on my 2004 driver's side headlight died and I had it replaced. Last week a new problem jumped up that I do not understand. The passenger side operates correctly. When I turn on the headlights at both go up. When I turn them off the passenger side goes down but the driver's side stays up and will not go down. I have to lower it manually. Pops back up normally when I turn the headlights back on. Seems to me that if the gear was stripped it should neither go up or down. Any ideas? Solutions?
Thanks!
Thanks!

Also, did you shim the driver side headlight motor with washers to move it out? There was a GM TSB on this for the driver side. Some cars have required this so the mechanical arm does not pass the metal tabs where the bump stops are.
It's been a very long time since I managed this issue myself. Here is a helpful link with pics of the bump stop locations. Typically you can just remove them and flip them over to the other side for them to work as they should. Worked for me 15 years ago and still working. Otherwise buying after market is the way to go. I picked up a few spare sets a year or so back from Zip Corvettes. They also sell the shim kit washers.

When I swapped out my headlights for the ACA Bi-LED's, I could see the wear on the bump stops, so I flipped them over as they only "work" on one side, so if all of them are there, if you see a gouge or wear into them, flip them over and try that. They are cheap to replace, but flip them over and try that first (if they are worn).
