Check your owners manual for your fuse panel, it will show you the location of the fuse panel, as well as the fuse location for the interior lamps. If the fuses seem ok, check your door switches, located near your door hinges on each door, they should be spring loaded, and mov in and out freely. It is very likely some dirt,or rust has locked one of the in the closed position, however if all the switches are funtioning properly, Check the interior dimmer switch, this controls your dash light brightness, as well as your interior lights. If you cant control the dash light brightness this is likely the culprit.

dimmer switch on the dash... lower it. it should click and should shut off the interior lights.

Can you open the door? Most likely the door is not making (enough) contact with the plunger which shuts off the lights. If you can get to this plunger, until you get the door fixed, either tape the plunger to the "in" position, or tape something to the door itself to close the gap between the door and the plunger to make the plunger go in. I have had to use quarters (25cents) and duck tape until more permanent repasirs could be made.
Also: there should be on your dash: panel and interior light dimmer/turn off switch. You can turn this/set this so the interior lights do not come on at all.

YOU COULD HAVE A FAULTY DOOR JAMB SWITCH.

broken wire in between body and door wiring

check your light dimmer & see if you have it set all the way down.If it's anything like my 99WJ it has an off setting when the dimmer is set all the down causing the interior lights to not come on when you open the doors,hope this helps

you need to check wiring between lf door and body..peel back rubber boot and pull on wires..you will find 1 or more broken wires..can be repaired

I would check the door adjar switches. IF all the door adjar switches check okay, then check the head light switch .

Assuming the head light switch and door adjar switches are okay , Then there is a wiring problem. This is the worst case scenario .

Check the dimmer control switch for your dash lights. Just turn it, Frankster016
