Power Window Fix
Just posting this as an FYI..
My wife was borrowing my truck (05 FX4 Scab) for some errands the other day and came home to tell me the passenger-rear window wouldn't roll back up. No noise or warning, just stopped working. The window was stuck fully down. I had seen posts about this on here before and figured I needed the clean the switch.
I tried both the door switch and the driver-door switch. When I pushed the switch down I could hear the motor kick in, but when pushing up it was silent.
I pulled off the door panel and tried gently beating on the motor while pushing the up switch.. no change. Nothing appears to be jamming the window track.
I disassembled the passenger-rear door switch.. it looked pretty clean already, but I shined it up and everything appeared to be working. Reconnected it.. still no change. Hmmmm.
I got out the voltmeter and tested where the wiring harness connects to the motor.. I'm getting a solid +12/-12v on the pins depending on which way I flip the switch.. motor must be shot.
I pulled apart the motor. Pretty clean inside.. nothing obvious here.. reassemble. I fab up some quick jumper cables to hook the wiring harness to the motor with the wires reversed.. window rolls up just fine, but now won't roll down.. Motor works, switch works, no wiring shorts.. WTH??
Google around a bit and find guys with similar problems that ended up replacing the motor and all door switches to fix. Ugh. Finally find this diagram:

Ahh! I'm no electronics pro, but it seems the driver door switch is integrated into the circuit.. not just a secondary piggyback switch.
Pull out the entire driver door switch module and disassemble. Lots o' dirty switches. Clean up.. reinstall.. Bam! Everything works again. (just in time for 15" of fresh snow)
Hopefully someone else can benefit from my slow learning and save some time down the road.

Much appreciated. Just got a used F150 and after a week went to put the passenger window down from the master switch with no luck. Used the passenger door switch and it went down, then went up with master switch. Now won't do anything. Will try cleaning the master switch first, was gonna be in there anyways putting in some new speakers. Thanks.
PS - @hockeyguy - you don't need to pull the door panel to get the switches out. You can just pop off the plastic armrest covers.
