2004 Endeavor. Both front windows would not roll up or down. Replaced motor/regulator on driver's side and problem was fixed. Replaced motor/regulator on passenger side. Hooked everything back up. When ignition moved to "on" position, passenger window immediately went up on it's own. Once raised, it continued to try and raise the window. I could hear the motor from inside the passenger door. Immediately disconnected the motor/regulator to prevent the motor from burning out.

I'm suspecting that it's the window switch but not sure which one. (Driver or passenger) I'm assuming it's not an issue of power getting to the switch. I'm leaning towards the passenger side switch because all driver side window/lock/mirror switches are fine.

I've been trying to locate a new switch plate but have run into some issues.

Any input on my assessment of the problem and help finding what I need would be greatly appreciated.

 

Try E-bay for a new switch.

If that does not work,check the wires going from the drivers side door into the car.This is a known problem area of wires breaking.
