'04 WJ Power Windows/Locks
I have seen posts regarding drivers side power windows and locks on the forum but most of the time the problem only seems to affect just the drivers side locks and windows. I have lost all power locks and windows front and rear, the interior lights stay on as long as the vehicle is running and then turn off after about 30 minutes or so after the ignition is turned off. Guess is this a feature that prevents killing the battery when someone leaves the interior lights on. Also, the overhead display said the driver's door was open, this message went away later in the day. I have checked fuses. Is there a specific fuse for the power windows/locks? I don't see one listed in the owners manual and there is no cover on my interior fuse panel. I did pull the interior light fuse as it was getting pretty aggravating with the interior lights on when driving to work at 5 in the morning.
This all happened overnight. Fine when I pulled in the driveway after work, next morning no windows, locks, power mirrors and the interior lights always on.
I have tried to check the wires inside the door boot but it's so damn cold out I'm afraid of breaking a plastic connector or something. Could the drivers side module have completely crapped out? Would it take all the other windows and locks out too? Would a wire break take them all out?
I just replaced the driver's side module in my wife's Trailblazer a month or so ago and it only affected the locks & windows on the driver's door, p-side windows and rears worked fine.
I appreciate any and all advice.
Thank you.

Re: '04 WJ Power Windows/Locks
This is the dreaded door wiring where it goes through the boot from the door to the body. One of the thick gauge wires (mostly the black one) breaks, causing this problem. I had the same happening on my jeep some year ago and still driving around with a temporary repair. The best is to change the broken wire completely, i just soldered the 2 ends together, but ofcourse one day this will break again.
On my jeep i could switch off the interior lights with the dimming switch in max dimm.

Thanks Frango for the feedback. Took it to the dealers asit's just too cold here to work on, no heated garage. They found three broken wires in the door. While it's in the shop, going to have the rear upper control arm bushings and ball joint (if needed) changed out. Been banging for awhile so figured might as well get it done while it's in the warmth.
