i have a different style jeep, but this might help. on my 97 gc, there is a second mini-computer under the rear seats. i believe it's referred to as the BCM (body control module) . anyways, it powers all the windows and door locks, etc. it might also have something to do with your panel (dash gauges). i don't remember everything it controls. mine is a black 4" x 2" little square box with an electrical connector attached to it. see if you got one too. it might be in a different spot. definitely check around under your seats though. it could be just unplugged. if it's like mine, the jack and lug wrench are all right there. somebody could have bumped the connector if they had to change a tire. you have to have something similar because the jeeps are only 2 years apart. all else fails, call a jeep dealership and ask them about it. BCM.

On my 98, none of my dash gauges are working also.

I have checked the fuse box, no bad fuses.

I just pulled the dash apart, and found no disconects,

or anything that looks bad.

Alot of lights, light up when I turn on the key, or start the car.

When I pulled the radio that does not work, I found a bunch of cut wires,

from the prevous owner.....



Will keep looking....
