Slow moving power windows, or windows that won't even go up or down are a sign that you should be visiting your local ACDelco Professional Service Center. Your car's power window system is a complex system that contains a motor, regulator, cables and a lift. All these components are contained within the door panel so the repair involves removing the entire door panel. This job is best left to the professionals.
