The first thing that I would do is check for electricty at the motors them sel and work your way back.If there is elec. at the window motor it's self susspect a motor problem.Remove the motor to see if it spins (but it dosen't me its good it could be week)next check for binding in the window mecanism.

Replace it with a Dealer or Aftermarket Part

SOURCE: rear window defroster, no driver heated seat

check the ground on the passenger side of the rear window under the trim panel. That is what was wrong with mine.

I would see if the haynes manual or chiltons manual has specs for the driver (main )switch so you can test ressistance. Sometimes when they go bad they can show up in one door, also verify voltage to the side rear window switch, as well as ground , the wire colors and location should be in the manual also, if everything checks out there start leaning toward the motor ,in that case you need to trace wire colors as well as schematics (manual), and bypass the switch to the motor directly this should identify yor culprit. hope this helps chris

I assume you've tried with the driver's door switch and the rear passenger switch and nothing happens. If so, then it's unlikely that both switches went bad and it points to a bad motor...
You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. You can test the switches at this point to see if they work. If not, you can then pull off the weather seal and access the regulator, motor inside the door that will be held in by several bolts
