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.

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.
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
if the master switch dont make window work has to be the window motor. if its the driver side window where master switch is.remove window switch shake wires will working the switch if window try moving switch is bad. if power is at the window switch and using test light to see if power going to window motor if no window motor bad if power going to the power window motor and its trying to move window and you can hear motor working the window regulator causing binding keep window glass from going up or down.
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.
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.
