Rear Left Window

I have an '88 Eighty Eight, with a rear left window that will not roll up anymore. I want to try and fix it myself, but need some help in doing that. Any advice will be helpful from getting inside of the door, to actually fixing the problem.

"..roll up.." meaning crank windows? I doubt that's what you meant, i'm sure its electric. All you gotta do is pull the door panel off and try to feed the motor with power from some other source (obviously 12v or less), I use a 7.2v Makita battery to check window and seat motors. Works like a champ, just a little slow. If that doesn't work, I'd say the motor's toast.

You could also try tapping the motor while someone holds the switch in the up position (small hammer or a drift pin ect. If this works its time for a new motor.good luck
