I own a 1991 chrysler dynasty, broke glove box and made the light in there spark now the radio, interior lights, aotumatic doors don't work, dont have a manual and dont know what spark plug needs replaced if thats even it. Or do i have to change the bulb?

Time delay relay is the relay that allows the interior dome light to remain on for a brief time when you enter or leave the car.Usually the lights will remain on for a few minutes and then dim down and finally off.

It sounds like the daytime running lights were put on that circuit and the relay removed to keep them on constantly.
This sounds like a time and material repair that a shop will have to do. Tracing the wiring installed by the previous owner may be required to find out what was done.

The SJB supplies power to the interior lighting system. The SJB will set DTCs if certain circuit failures exist with the interior lighting system.

Check fuse # 3 SJB

it is your body control module. . did not mix it up with the computer. the bcm runs every thing inside the car locks/radio/mirrors /etc.. in your car it is part of the fuse box under the dash

I hve the same problem go under the hood for the fuse box you will c a fuse that has a blk clip around the whole fuse it self to open it use a small screw driver the ones u use for ur glasses nd open it c if it needs to be changed out if good jst unplug it nd c wat it does on my car I jst unpluged it nd now everything working I think its called a iud some wired name but u can't miss it good luck

Yeah sounds like it. You didn't specify the year, make, or model ! Cadillacs have 3 fuse boxes. One on the drivers fender under the hood, one under the drivers dash, and one in the truck on the drivers side.

the radio and interior light is normally a different fuse to the windows the windows will be a 30a and the other a 7.5 or a ten max ,could be a corroded fuse holder in the power supply box under the bonnet

First, check the dimmer switch (should be the same as the headlight switch) and make sure it is not turned all the way to the right as that will turn on the overhead light.
If you are sure the door switch is fine, then I would replace the dimmer switch.

check fuse its behind the glove box door.you another set of fuses in the power distribution center under hood next to left strut tower.

I would check the button switch's on each door, If you have a damaged door or one that has worn hinges maybe it has enough movement on the bumps to allow the switch to turn on the lights
