I have a 91 rs and my passenger window stops when going up. It will go up some and then stop again. Then I wait a minute and it will move up just a little more. Is it just a bad connection? How do I fix it?

 

You probably need to get inside the door and grease the window tracks. IIRC the windows work on a thermal circuit breaker. If the motor is struggling to raise the window itwill cause extra strain on the motor/ heat in the circuit. This causes the breaker to trip & then reset after is cools (doesn't take long, similar to how a turn signal flasher works really I guess). The other possible problem could be the motor is dieing and causing the same fault. Don't quote me on any of that because I'm not 100% sure about the breaker.

 

Most likely the motor brushes are worn. When they get low the get very loose in the brush holder causing erratic operation. The thermal breaker is a simple bi-mettalic strip that warps under extreme current opening a contact and removing voltage from the motor. Even if the tracks are dry as DB says, generally the motor will labor for a bit before the it thermally cut's out. Chances are upon inspecting it you will find it's simply the brushes.

 

yup the same thing happened to me, the brushes in the motor were shot the heck!! so i bought a new motor and all is well....

 

Thanks a lot guys. Could I get the motor from a local auto parts store? Is it fairly cheap and should it be pretty easy to install?
