I apparently have the bushing failure beginning in my 91 couple. In planning this was thinking of what makes the motor stop running after it hits the mechanical stop? Motor load or how many turns on the gears? I'd like to know just for the hell of it.

Thanks

How does the motor know when to stop? I will much regret will start this work this week! I sold the car and now Im fixing it go figure

 

Well, there are two stops associated with each light. One stop will stop the light in the UP direction and the other stops the light in the DOWN direction.

If you look down in there and at the raise/lower arm on a properly working light, you'll see that the raise/lower arm is making contact with one of these stops.

Well, if you are having the problem of your light cycling up and then back down or down then immediately back up when you operate your lights, what has happened is one of these stops has BROKEN OFF!

Yep, I can nearly guarantee you that if you are reading this and have this problem, you can go out to your car and look down in there at the light which is working properly and see two stops.

On the light that is going down then immediately back up, you'll see only one stop To fix this isn't easy but isn't all that hard either. Because these stops are actually molded right into the front headlight support assembly, replacing the stops means replacing this entire piece and that is big $$$.

You probably don't want to spend that much and I don't blame ya! Good news is that you can make your own stop What you need to do is drill out the area where the stop used to be then using a bolt and nut or nuts, make your own stop!

I have never done this myself and only suggested to people to do it so I don't know what the best size to use is. Size isn't overly important here… just so long as it sticks out there far enough to make contact with the raise/lower arm but not so far as to cause interference with the operation of the light.

Also, keep in mind, that if you were having problems with the light jamming in place, that you can use a bigger nut/bolt which will cause the light to stop a little sooner and thus help to prevent the jamming of the light… killing two birds with one stone.

 

My stops are in place but what triggers the motor to stop running? These are not interlocks or switches they look like rubber bumpers. so what makes the motors turn off? not trying to be a pia but i still dont understand
