Brass Gear Question ..... I know I'll Make it quick
Had that damn grinding noise on the drivers side. Ordered a new gear from Rodney Dickman. Installed it last night, took about an hour for me, I know some said they put it in 20 minutes. Maybe im a lil slow. Anyway I followed the instructions to the T, hooked everything back up. The noise went away, but now the driverside headlight when turned on pops up and down repeatedly, then either stays up or down ?? Did I install wrong? Not sure, I know there are a lot of threads on this because I did search them. If anyone experienced this after installing the brass gear please chime in. Thanks

Based on your symptom, sounds like someone dropped Viagra in the gas tank.... 
Suggest going back to check your electrical connections -- especially the ground -- and look for a pinched or shorted wire.

Danny,
You may have a problem with the insulators. there was a TSB out for that a few years ago and you need to fit replacement insulating washers. Here's the info:

I checked all the grounds last night. No bad wires or connections. Took the control arm linkage apart and reinstalled it. Now the lamp raises no problem, but when closing pops up and down several times before it's final close?? I think the problem is the motor is not sensing it when it closes? ANY THOUGHTS?? ANYONE?

Sounds like a grounding issue somewhere. As for the lights not wanting to stay down, check to make sure that you didn't get the motor arm BEHIND the stops. It can happen when re-installing them. Also, when re-installing the motors and light, I found it best to completely lower them by hand, turning the **** as far as I could, then re-plug them back up, and turn them on and off. That way, I could see that the motor arm was completely against the stop on the bracket.

Did you replace the gear on one side only? If so - you might have a problem with the other side too.
