Passenger power window will go down but not back up. I replaced the motor, it worked for a month and now it will not go up. Ford replaced the motor. Still doing the same thing. I have plugged the motor on the driver side and it works just fine. I am thinking that there is a wiring problem. Does anyone know where I can get a wiring schematic?
I also would suspect a switch bad. I have the same problem on my 06. The only time it's a problem is when the wife is riding with me and she rolls down the window and it won't go back up. I checked with the parts guy at my dealer and he told me that the passenger side is a little more $ than the driver side.
It ended up being the main power window control (driverside control) switch, it has Corrosion on the contact. We are going to pull it a part and clean the contacts before we spend $70.00 at the dealership for a new one. What I found out is if while pushing it up or down, which ever direction is not working, if you hold it to the left while pushing the button it will work. Thanks for the reply.
Just used this info to fix a window switch. Was relatively easy. Only two problems:
1) The plactic tabs are pretty brittle, and they broke when I was prying it apart. Now it's all loose.
2) the little pins inside are worn down. So the dirty contacts are only half the story. I'm doing to go to the junkyard and see if I can find some more of those pins, I have a few bad switches, and if the pins are the only issue, I'll be in business for nearly free.
It would be hard to say without checking things out. But the switches have been problematic in this generation of F150. I have yet to need to replace a motor, but I have replaced 2 of the switches in my 06 F150. I cleaned the contacts on my old switches for backup and thru them in the console.
