Many times a power window will only roll up. Or just down. Or do nothing at all. If there is an issue with the flow of electricity to the power window. These problems may happen. Window doesnâ€™t do anything when using the switch. Only rolls up or down. Many times the switch has false contact and doesnâ€™t allow the circuit to continue to the motor/regulator that drives the window up and down. The motor/regulator can be damaged and doesnâ€™t function correctly, Blown fuse, short circuit. Whichever occurs. We can fix it. By diagnosing the problem and fixing it right the first time.
