My driver side window has stopped working in my 75 Coupe. When I push the switch the AMP meter movers over to the charge side of the mid mark. Dose this mean the switch is OK and sending power to the motor, and that the window is jammed? Or could it be a bad switch.If the amp gauge moves, the switch is fine. Either the window is stuck, the motor is stuck, or the regulator gear has shredded or has a disintegrated bushing.
