If it's all I would think fuse or wiring. Does the car start and all the rest of the electronics work?

Here's a download for the 2000 GA Owner's Manual to help you out with fuses:

IM reading to 2002 GP Manual right now. Thanks!

Fuse would be the first suspect, also look to see if you also have a window relay in the circuit/fuse block. It may also failed. Last thing to consider is the master switch in the driver's door may have gone bad. It that is the case, you will have to replace the entire switch unit. Also look for loose electrical connections along the way as well.

Shark, I hope for you it's a fuse, but I doubt it! Most likely it's the ignition harness. The door widows and sunroof aren't on the same fuse. The ignition harness is a typical problem in all of GM's late 90's on till they changed to the can-bus wiring system. The GPs ignition harness uses 5 main 12v hot wires. 1 in 4 out. The switch that the harness is molded to is the problem. It has finger contacts , like distributer points, these fingers burn like points do. When they burn bad enough they won't flow 12v any longer. In most cases the only carry millivolts. Most likely you will find more things than just the windows malfunction. Each one of the 4 12v leads feeds a different group of components. The harness cost about $100.
