I've got a 1994 Mustang GT. The drivers side window was working fine and one day just didn't roll up. I went out and bought another motor and hooked it all up and it still didn't work. I then tested both of the motors and both worked when they weren't hooked up to the car. I checked and there is power going to the button. There is power going to the motor when I press the button down. There is power going to everything and there are no blown fuses or anything and it just doesn't work. I'd appreciate any help I can get here. Thanks.

 

By the way the switches both work. I switched them around and both moved the passenger window.
