All wiring for the windows go through the driver's master switch. While it's possible that the master switch is faulty, it is more likely that you have a broken/damaged wire in the boot like
98rig said.
Having said that:
I had similar electrical issues with my 02 xlt. The dome lights would stay on until the battery saver feature turned them off, the accessory delay wasn't working, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, the delayed accessories didn't work, etc. Recently all 4 windows stopped working. Most recently the driver door lock actuator stopped working.
A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I have found 3 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ. I had to repair the pink/black wire to fix the driver door lock actuator.

Be sure to take your time when looking for broken/damaged wire(s). Check all the wires for breaks/damage. When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.
If you come up with nothing, here is a great link for troubleshooting the power windows, thanks to
