Headlight motor gear fix issue...

[StuntmanMike]

So my headlight motor has been grinding, which is a symtom of a worn gear. So today I finally got around to trying the quick fix of unhooking the arm off the motor and rotating the motor 180 degrees with the knob.

Technically, that did the trick. The headlight now goes up and down w/out grinding.

But, I have a problem now. When shutting the lights off, the door goes all the way down, then the motor reverses a bit, and the door raises back up about a 1/4 inch. So yes it's shut, but it sticks up a bit and is not down as far as the other side.

I tried unhooking it and rotating the knob a little bit more, but that didn't help.

Is there some way to adjust this??

Thanks!!!
