Question about 1993 Pontiac Grand Prix

1 Answer

3 of the 4 power windows don't work

Only the right rear window works on my 1993 Grand Prix. Replace the 4-way master switch but it still had the same problem. I can hear a noise in the door when pressing the switch for each window--at each window site.

Right rear window does not work

All power originates/passes through the master control switch on the drivers door panel. Start by popping the drivers switch and with key on check power going to & through the master switch especially the switch that raises/lowers the window in question. Surely you've done checked the fuses and or relays? Hope this helps.

How to replace a power window motor in a 2002 grand prix 4 door where none of the windows are working. I think there is one motor in the driver door for all windows. How about a diagram ?

Each window has its own motor. If NONE are working, check the switch. The YELLOW wire should be HOT. 12V its on a 30 amp circuit breaker. Unusual to lose ALL the windows, unless the switch is bad OR no power to the switch. The other windows get power through the main window switch

Power windows dont work

If all four windows are out using the master switch you have a faulty master switch. Most of the time the master switch goes out either because the driver one time or another spilled a beverage on the switches or the wiring connector to the switch caused a short and fried the switches. Test for power at the switches. if you got power to the switches and no power at the window motors when testing you have a bad switch assembly.

2000 pontiac grand prix the left rear window will not go up or down from master switch. It will go down from lr switch but not up. Tried new motor and another single switch. What could be the problem?

You might have a bad master switch. Generally, if a window, other than the drivers door, doesnt work at all from the mnaster switch, but does from the individual door switch, its usually a bad master.

Power Windows

I assume the fuses have been verified to be OK. As long as they are, it seems that either the window regulators in those doors have failed, or there is a break in the wiring between the doors. The most likely problem after fuses though is that the driver's door switches themselves have failed. Power is routed through the driver's door before being distributed to the other doors. If the driver's door switch module has died, then the other switches for those windows won't work either. A replacement driver's switch pod is easy to swap and runs around $10 at a salvage yard - I'd try that after verifying that the fusing is all OK.
