hey folks
i have a 2004 f-150 xlt supercrew 4 by 4 .all controls locks windows and mirrows quit! you can control locks on other (passenger side) door but windows wont work on any control. checked fuses ,relay,delayed accessory all ohmed ok.
pulled control panel in dr side and found no loose connections.i put a meter on wires to motor in door it reads voltage when you push the window up and down
as though the motor/regulator is bad but why is the other three windows out?and mirrows.are they wired in series ?
need help thanks! alex

 

The best way to test the window motor is to hot wire it. What I mean is run a hot wire to the motor and ground the motor. If the motor works it is the switch if nothing happen it needs a motor or the window is off track and in a bind.
