Broken wires in the door harness? That's what happened to my 2k 4door. I pulled the harness out of the door and patched it up. Worked for about 3 months. The wires break in the rubber boot where they flex and move when you open the door. I'd start with holding the window switch down and wiggling the boot see if anything moves. If it does, check the wires. It not. Check the window motors
