I was on a fishing trip this week and my passenger side window would now return up with the switch on the driver side. Once I stopped I reached across and the passenger side switch worked. My drivers side window still works fine....does anyone know if this could be a switch problem? I took it apart and cleaned the contacts with no results. Thanks in advance for your input.

 

Did you verify that the contacts on the Driver's side switch is not broken? They are small enough that it sometimes hard to see.

Check wiring as well.

 

Pay attention to the wiring that goes thru the nice rubber boot from the drivers door, into the truck. Opening and closing the door fatigues those wires, and they have been known to break.......

Start with the switch as stated above though.
