2002 Pontiac Grand Prix SE, with the terrible 3.1 in it.
Its my girl friends car.
The car has not had windows that rolled up and down for a while. Her dad bought a new master switch, it worked enough to get the window rolled up but stopped working right then...
I took the door panel off and was going to test it with a multimeter, and magically they started working. So I put it all back together and about 10 minutes later stopped working. Now I cannot get them to work at all.
The unlock button works, but the lock button does not work on either side aswell.
Im thinking a short in the door, but is there a way to get a wiring diagram to this car? So I can trace it around and find out.
Thanks
Matt
