Window problem..
 

Stumped but I think it's figured out....

Passenger window gradually stopped working. It went up and down at normal speed but wouldn't move every time. Motor turned out fine. Passenger switch ohmed out. 12 volts going to it. Drivers side door, passenger window switch is fine. It would move sometimes when I would hit a pot hole or giggled the wires going from the door to the cab. All the connections on the quick disconnects looked fine.

My dad's friend thinks it could be a faulty wire going from the door to the computer. Is there a good website or place I can get a wire harness going from the passenger door to the computer?

Sorry if I sound ignorant. I am lol Anyone else experience this? I searched and only found problems with window motors...

The Grand Cherokee's are known for the wire splitting in the sheath that runs from the door to drivers kick panel. That would be a good place to start looking.
