Good evening, Forum
I have probably read 100 posts on the forum tonight troubleshooting my window lockout problem. The closest solution I found was posted by Buddyhead and Ford123 on 3/30/2011 but it still wasn't my exact problem.


Up until two weeks ago all my power window functions and lights were working from their respective locations. Now I am only being able to control the windows up or down from the master panel on the driver side door. If I have any passengers in the truck the have to ask me to roll the windows up or down for them also none of the lights on the passenger and both rear illuminate. They are locked out regardless on whether the window lockout switch is engaged or disengaged.


My question is does the entire circuit share one common ground or is the window lockout switch grounded separately. I ask this because I have all functions operational from the driver side control panel.


Any troubleshooting tips will be greatly appreciated.

It sounds to me that the master switch is faulty. Like it's stuck locked. You can get a new aftermarket one on amazon for less that $40.

Thanks for the quick reply Lewissa81. Do you believe that the faulty switch would also keep the light from illuminating in the up/down switch at all three doors (passenger, and both rear).

Your lucky I have insomnia! I don't know about the illumination. That may mean there's something else. Tomorrow I will check on my truck if the other switches glow when the lock is on. That's something I've never paid attention to. If all 3 switches quit working at the same time, then I would think there's only one cause. But if they quit at different times, then you may have some wires inside the door broken.

Apparently when you lock the other window switches, they do not illuminate. That's a pretty cool little feature. I guess I just never paid attention. So, I think you have a bad master switch.

Update: Window lockout switch does not work. Confused!!!!! I have a co-worker with the same year model truck that I have. We parked side by side and I decided to swap out the master switch with his master switch. All functions work on his truck (Power windows, power locks, all switches illuminate with the exception of the window lockout switch which is not supposed to illuminate. I wanted to swap them out before ordering the master switch replacement.


Well guess what? My master switch works perfectly on his truck.( Everything works). So I installed his master switch on my truck and I have the same problem. All power windows can only be controlled by the driver side master switch panel. Now I know that my problem lies in one of the three wires that come out from that window lockout switch at the master panel. I think tomorrow I am going to start out by following the wiring harness that leads to the master switch. Now I am convinced I have a broken wire leading out from that connector to the other three doors? Wish me luck!!!!!!! I will post results.....

That's weird man. Good luck with that! I know the wires in the rubber conduit from the door to the body have a tendency to break.

Not sure if this helps but here's the electrical diagram. Hopefully just a simple break from the master lockout switch feed is all it is (which could be possible if all 3 switches went out). I've given you the pin layout for the other switches as it may help you narrow it down if you have a multimeter. I'm convinced it's related to your lockout though, if you had a disconnected ground you wouldn't be able to work the windows from the master switch, you'd lose it altogether. Anyways, hopefully these help . Lewissa makes a great point though, that master feed might have broke in the door.

Thank You, Homer
The schematics will sure come in handy. One more thing I failed to mention is that I removed all three switches (passenger and both rear doors) took them apart completely and cleaned the contacts with an ink eraser and reinstalled them with no luck. The 30A circuit breaker was ohm'd out and it was not open so that also checked out. I am not sure but I imagine that if it had been open circuit I wouldn't have been able to operate the power windows from the driver side master switch at all. Thanks for all the good suggestions especially the connector diagrams. I will post when I find the problem.

Lewissa81 and homer,


Thanks for the guidance in solving this problem. The wiring diagrams and connector descriptions sure helped. You guys have your *%8 together. I had a broken wire at the driver side A-pillar junctions covered by that corrugated rubber grommet. It was the yellow wire with green stripe that powers up the window lock. There was one additional wire about #24ga that was also broken so I spliced it as well. I checked all the connectors at the driver side master switch and the only purple wire I saw led to the power mirror adjustment **** but both mirrors were working anyway, so maybe it was one of those wires that is not used. Nonetheless thanks for all the help.
THANKS
