I just got my rear left side window to work after 3 years of it not working. Luckily it was stuck in the "up" position. So I took the rear door panel off, peeled back the weather membrane, disconnected the wires and door handle, loosened the 4 bolts on the motor then put it all back together again. Somehow it fixed the problem! Worth a shot. O'Reilly Auto wanted $310 for the motor and didn't carry the regulator so that would've been purchased thru the dealer. I read that holding button up or down for 12 seconds and slamming the door a few times while still holding switch worked - but not for me. Also read that loosening the motor and having it lowered a hair worked too. Mine was at its lowest spot but still didn't work. Wish I knew what I did that fixed the problem.
