I'm working on a 1997 Ford Mustang atm, have automatic windows, and the driver side will not go up at all. I have at this point replaced the motor/regulator, I have tried some nonsense regarding slamming the door/hitting the motor slightly while holding the up switch, I have replaced the switch, I have cleaned the contacts for the switch. When i press the down button I can hear the motor click like it is trying to go down, but it is already fully down so obviously it won't do anything more, but when i press up, absolutely nothing happens, anyone help me out here?
