I have a 2005 Expedition. I'm having a problem with the pass. side power window. It started out that it would roll down, but not up without hitting the button about 50 times (like a short). Now it won't go either way. It's not the motor, already tried one. I've got 12 volts at the plug to the motor. Any suggestions?

 

You can try using a jumper wire at the harness of the switch and see if it goes up or down. Does it work when you only use the master switch. Try jumping at the passenger door switch harness and the there reconnect and repete at the master switch. I wish i had a wire diagram i could help you out with although i do not have access to that info outside of work.
