My instrument panel lights are not working but I cannot figure out where the fuse is on the fuse box. This is a 1989 wrangler

Go online and download an owners manual for the Jeep. It will give you the location of the fuse associated with your dash lights. Or you could start pulling fuses and looking for the one that is blown.

Every thing works in my fuse box but the

i would start at the ignition switch as thats where the power comes from to power up the fuses for these components, there are power wires from the engine compartment that come throught the dash in the center or rather come through the firewall, i belive its about 4-6 wires with a connector plug under the center of the dash, the connector heats up and causes a bad connection,start by located that first then check the postive side of the battery for a bad power wire connection if its not the main power wires that i told you about in the center of the dash, you can get to them from the driverside under the dash. let me know the outcome.
