I've had issues for a while with my windows and locks on my 04 fX4 Screw. Never got around to messing with them too much. It's getting quite annoying with the warmer weather coming. First things first, I just replaced the driver's door master window switch and still have the same issues... The driver's side rear window will not roll down with either switch, and will only go up with the switch on the rear door... The Passenger side front window will only work wit the driver's door switch and only intermittently with the passenger switch. Not sure whats going on with them. The door locks are weird as well. They work fine but the rear doors will not always fully unlock. When that happens I have to rapidly lock and unlock the doors and eventually they unlock fully... Any help would be appreciated...

 

Have you checked the wires where they run through the rubber conduit between driver door and the truck. Common for the wires to get get pinched and cut.

 

I haven't... Thanks for the tip!

 

Yeah give it a look, push the tubing all the way towards the right or towards the truck and get a good look at the wires. My driver side window stopped working and I found the wire completely cut. Works good now that I reconnected it:-)
