Electrical Problem - 2003 F150
i own a 2003 f150 supercrew 4x4 5.4l v8. Recently the power windows went out and now no interior lights are working i.e. dome lights and passenger lights. When i try and roll my windows up/down, nothing happens. No clicks, no window mottor running, nothing. I grabbed owners manual and checked the main cb (as defined in the book) which was cb 601 in the power distribution box, ohmed it out and it was good. Havent been able to figure out how to test relay 4 in the fuse panel inside the cab so far. still searching for ways to. Any ideas on what the problem could be? any help would be greatly appreciated, Thanks

If you don't find anything such as fuses or switch, both windows and lights have common control functions from the Gem Module.
That module is on the back side of the dash fuse panel.
It is specific and programmed to your truck's build so is not just a general replacement item.
You may need to see a dealer for help.
Good luck.
