Electric Window Problem

I have a 2003 Ford Ranger with electric windows. All of a sudden, the passenger window will not work from either switch. (Driver or Passenger side) Pulled door panel off and no loose or corroded wires. Anyone know if may be wiring problem or is motor shot? Any way to test motor?

Thanks!

Motor is probaby shot. Try whacking the motor a few times to see if it works. If not, the get a test light and check for power when running the switch. It could be wiring trouble in the door jam.
