my passenger window will let down but will not go up. I've changed switches with no results. I'm losing my ground somehow. I ran a jumper wire and it will go up butt he wire gets really hot. Any ideas??

Yes the ground is screwed into the driver door. I used a test light on the passenger side switch. I am losing the ground going up so I put a jumper wire from the switch to the door and the motor worked

Is it one window or both?

I think you narrowed it down to the wiring.
