HOW exactly does it "not work"? Does NOTHING happen, or do you hear the motor spinning & the glass doesn't move? If the motor spins, read this caption:
If the motor doesn't spin, pull the screw for the driver's switch bezel, pop the bezel up, remove the 3 screws for the switch connector, pull/pry the window switches out, and install jumpers to find out if the problem is the switch. For driver down, jumper Y to LB/Bk and Wh/Bk to Bk. For driver up, jumper Y to Bk and Wh/Bk to LB/Bk. Study these:
.
If the motor works reliably with the jumpers but not with the switch, then the switch is bad.
