I have a 97 f-150 4x4 pickup with an electrical issue with the power windows. They just stopped working. No blown fuses and have verified that I have 12 vdc on the light blue/red wire to the switch on the drivers door. Both windows are inoperative. Is there a hidden relay somewhere that I’m not seeing. Don’t have an owners manual but just bought a chiltons manual and the scumatic is not too bad but some of the component location such as relays are not listed.

Do they have a safety lock button that you pressed accidently?


#3

Both the power windows are controlled thru the GEM or Generic Electronic Module. This is located under the left side of the dash at the relay/fuse box. Since both windows have stopped working, and these GEM’s have a reputation of failure on Fords, most likely that’s where the problem is.

Could the GEM also cause problems if just 1 window doesn’t work? I also have a 1997 F150 where the passenger window stopped working years ago. Then earlier this year it started working again for a few weeks and then stopped working again. Just wondering if it could be the same problem as the OP.

It could be, but it could also be wiring, a switch, the window motor, or the window regulator.

Thanks for your reply, maybe some day I’ll figure it out. I’m hoping it’s not something with the wiring as I actually tried taking a quick look at it this weekend and could see that chasing something like that is beyond my abilities.
