One headlight motor is all out of sync. Help!
Recently, I put new metal gears in my headlight motors and everything worked correctly for a couple weeks.
But now, my left headlight is totally out of whack.
The headlights seem to turn on and raise as normal.
But when I shut the lights off, the left light cycles down and then partially back up again. The right light stays down correctly, but the left stays up.
When I turn the lights on, the temperamental left light cycles down and then back up, the right light operates normally, and now both lights are in the up position.
But when I turn the lights off.... here we go again!
The left light doesn't stop when it gets down, it pops back up!
What is going on here??

DeeGee, that's it!
Of course, I figured it out just before I saw your post.
The arm was missing the stop, swinging right by it. I tweaked the arm a bit, got it back in line where it should have been, and now it operates properly. Pretty simple problem, pretty simple fix, but it drove me crazy trying to diagnose it.
Thanks.
