Having problems with your 1993 Pontiac Grand Prix ?
3 of the 4 power windows don't work
\015 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.\015
Probably window regulators. Requires removing door panel
