04 Grand Prix window problem

The regulators do like to break. Seems odd that it's in multiple doors at the same time though.

I believe all power for the windows run through the driver window controls first then run out to the other windows. so if all windows are having issues that might be the place to start. I have had similar issues my 05 gt and simply cleaning all the contacts where the harness plugs into the switches fixed it.

My 2004 Pontiac grand prix window on driver side won't go up

Does it try to go up or is it just dead. The window regulators can break so when the motor tries to move the window it can't. The motor itself can burn out although that is much less common. Could also be the switch itself. I rebuilt one of mine by borrowing parts from one of the back door switches. And of course there's lots of wiring that can possibly get pinched somewhere or come loose. Do some trouble shooting (or have someone do it for you) and find the problem before you start spending money on the wrong parts for an old car.
