power windows not working
Hey all, happy holidays. :)
The power windows on a buddy's '92 coupe are no longer working. We are having little success fixing this. Here's the symptoms and what has been checked...
* At first, the driver's window was fine. The pass. window would fail once in a while, and fix itself shortly thereafter.
* Now, both windows no longer work.
* Swapped circuit breakers on the passenger side fuse box, didn't help.
* Grounds at the driver's/passenger's kick panels seem to be okay. (My '96 shop manual says only the driver's side ground is used for the windows)
* Swapped the driver's side window switch with a unit from Contemporary, still doesn't work.
* The dashboard voltmeter drops about 0.2V when you hit either window switch.
Any ideas? I'm leaning away from the motors because it seems unlikely both would fail at the same time, but now I 'm at kind of a loss after the new window switch didn't cure it. Any ideas :confused:
Thanks and have a great weekend :cheers:

Re: power windows not working (JasonL)
you need to replace the motors... try this... slam the door very hard a couple of times. if the window works, it is the motor...
they are about 60.00 each from carfan18, Jeff Kopp 1-800-728-8267

Re: power windows not working (JasonL)
Remove the wire connector from either window motor, connect a continuity tester from either of the motors terminals to ground....if no continuity is seen, the motor has a bad brush contact. If continuity is seen, check for +12V being applied to either terminal when the switch is depressed. ( Measure between ground and one or the other terminal, not between both terminals ). If no voltage, it is a switch problem.
Window motors that get little use will fail due to corrosion on the commutator where the brushes connect. This can be repaired if you disassemble the motor. ( I just fixed two PW motors last weekend )
Just so you know, the window motor has a built in circuit breaker, there is none in the wiring to it, except for one in the fuse panel.

Re: power windows not working (BBA)
Thanks, guys. Looks like bad motors are leading the polls. The corrosion explanation makes sense...I will pass the word to him and hope this fixes the problem.
