Flippin' headlight
Well, I replaced the gears that raise my headlights (left one started grinding) and got everything back together and worked fine --- for about five minutes. Now the right headlight cycles about 4 or 5 times up and down before it stops. Anyone had this happen and what did you do? I'm guessing a stop is out of place. Thanks for any help!!!!!!

You could try manually opening it and then allowing the headlamp control module/motor to do their thing automatically. That may reset the logic/adjustments. If that doesn't work, I'd be focussing on the headlight contol module. maybe check the grounds are tight
This post is for the opposite problem (stays closed) but it describes whats going on when the mtor operates.

One thing that I did when working on my lights was to fully raise or lower the one I was working on to match the other BEFORE I plugged power to that light. My mode of thinking was that one module is controlling both lights (I don't know that for a fact) and I didn't want to cause any confusion when the signal was sent to both lights simultaneously. Now I could be pissing in the wind but I have never had any issues like the ones I've read here.

The first thing I would check is that the arm that raises the light is screwed on the way it's supposed to. Make sure it's attached to the motor axel properly. It's oval shaped so the hole on the end of the arm and the axel have to be lined up properly to fit all the way on. If it's not all the way on, the arm won't catch the metal "stoppers" and the motor will just keep turning, resulting in your headlight continuing to cycle. I've been messing with my left headlight motor a lot lately (can't get the freakin' glue to hold) so I'm pretty familiar with all of the mistakes that can be made here. Good luck!
