Power windows
Ok guys , it's my turn, while out site seeing my back seat power window don't work , the control from drivers seat or from the back seat door control, I popped both covers on the control switch and both are firmly plugged in, I don't have my meter with me to see if power is running back to the switch , this morning I'll try to switch out the two back seat controls to see if I can get at least that window to go down , 04 350 , would there be a fuse for each or is it in the switch in the door that the harness plugs into , that's the only window that won't go down , Thanks Guys .

Both rears not working? You didn't hit the lock out on the drivers door controls by any chance.? Sounds stupid but I did it to myself once.
Missed that you said only one window not working. Back to square one.

The most LOGICAL cause, would be where the harness runs through the rubber flexible cover from the body to the door itself has one of the power window wires broken. All a power window is, is a simple circuit that supplies B+ on one side of the motor and B- on the other side to function, and switching the two polarities to function in the other direction. The switch itself is what directs B+ and B- to the appropriate sides of the circuit depending on the desired operation.
Resist the temptation to "shotgun" a power window motor and/or switch to repair the problem without first diagnosing B+ and B- are present where they need to be.

My drivers side front quit working. Pulled the switch apart and sanded/cleaned the contacts. It's been working for two years now. Hope this helps.
