If the other windows are working and there is not a blown fuse then I would suspect that the motor is the problem. It "could" be the switch that operates the motor, but the motor is far more likely. As to a possible fix that does not involve replacing the motor Ive got no idea. I would hit up vines automotive in AL (assuming you are stateside) and see about getting a motor from them if you do not want to purchase a new one. They have always treated me well with good prices and quick shipping.
