Interior lights stay on, on 2004 jeep grand Cherokee. How do I fix

the switch is bad. replace it
wires to it shorted. damaged.

Just recently, I inadvertently removed the yellow doohickey that holds the 2 x 10 amp fuses in the interior fuse bank of my 2002 WJ Jeep Grand Cherokee Laredo. I checked the fuses and they were ok so I inserted the fuse holder back in.. Low and behold the seatbelt and airbag light came on and stayed on. After several quick fixes etc to get the lights to go out, I finally returned to the fuse holder and discovered that A. You need to squeeze in the tabs to get the fuse holder out and B. the fuse holder when being re-inserted will not automatically clip in... you have to squeeze the tabs again to press the fuse holder fully home. I started the old girl up again and no more lights.

Have you tried checking the dimmer switch for your instrument panel? I believe if the switch is slid all the way up it will cause the interior lights to stay on. Hope this helps.

I read several posts where individuals were having almost the same problems. We checked the boot between the door and car sure enough there was a yellow wire broken. We fixed the wire and this fixed all the problems. Everything is working fine. Thanks your website is the best.

I had this same problem but no sunroof on mine. there is a bundle of wires that goes into the door and if the power wire breaks and the power window lockout was pushed when it happens no windows work and the dome lights stay on on mine it happened on the drivers side it was an easy fix i took the door panel off and unpluged the harnes and pulled it through the inside of the jeep and spliced the wire back together and it has been working since.

i had the same problem, it is a relay in your fuse box under the passenger side dash. i think it says courtesy lights on it.

The drivers power window switch is also a computer. I have found a broken wire in the pass through loom between the drivers door and body.

Common issue with the early 2000 series Jeep is the window/door lock control on driver side goes dead when the thick guage wires in door become brittle and break from continually opening and closing the door. Had both the ground and hot wires break over the years and both are fixed by making a simple jumper connection with a little extra length added.

Fixing is relativly easy if you know how to crimp wire connectors otherwise you my want someone more experience to help.
Open door, pull back rubber sheath and expose wire harness, unclip the plastic retaining clip and pull out wire harness and located which wire has broken (typically the thick black or orange wire) . Prepare both ends for crimp connector and make a jumper with small peice of heavy guage wire and crimp connector of either end then connect each end to either side of broken wire, tuck wires back in, replace retaining clip and rubber sheath.

You can find videos on youtube showing how to fix

I had the same problem.....there is a rubber boot that covers the wires going from your door to the body of the car.... the heavier gage wires eventually crack from the opening and closing of the door....you need to cut the rubber and get to the wires inside and splice them back together....the first time i had this problem my windows did not work...then a few months later my interior lights would not go out....different wire this time ...easy fix....

you need to check the fuses.
The fuse can have the leters, ill. int.ligh, dome light. cigar.
See your manual, if you have it.
