my drivers door window switches have never worked on either window but the passenge door switch would control the passenger windo, last night i went to roll the passenger up and now that switch does not work either, the fuses are good but i have no diagram for what wires are the power wires on the switches any help welcome!!!!! or has anybody run into this problem maybe a ground
 
You need to go to Autozone.com and get the power window wiring diagram. These, and the window motors are a bit harder to test than other plain old switches, because the switches are 2 pole, ie, they switch both power and ground in both directions. You can pull the switches and test across the pins, and also test the motor with 12 v for up and down. At least the Mustang does not use relays....
 
i tried to find it on autozone but no luck i may be overlooking it i would like to know will pole has constant power so that i can check and see if power and grounds are coming to the switch
