my back lights wont go on 1988 jep cherokee , fuse box? first? ___________________________________________________

Depends on which back lights. The back of a jep could have tail lights, parking lights, marker lights, stop lights, turn signal lights, backup lights, etc.

Please; more info about the problem with your jep.

Good luck.

lol Brake lights work but tail lights don't. I replaced all the fuses still nothing. Is there another fuse box besides under neath the steering wheel? ................... "THINKIN"

The front marker lights and the tail lights are on the same fuse, so if the front marker lights operate the fuse is okay. Then the most likely cause is a bad ground at the tail light. Be sure the ground wires from both tail light sockets are firmly attached to a clean metal grounding point. A less likely cause is a broken power wire to the tail light sockets. Turn on the tail light switch and check for 12 volts at the ends of the wires where they meet the sockets. If there is no voltage, trace the wire back to the switch to find the break. Good luck. ................Rodan.

Okay, backup lights, signals, and taillights are good but the "running lights" that come on with the headlights are not?

First of course, check the bulbs. It COULD be both bulbs. Make sure the headlights work.

On some cars the headlight relay turns the things on, and a bad headlight relay can cause an issue like this. But that's the point at which you need to get out a meter or a test light... make sure there is no voltage at the socket and no voltage at the headlight relay output before you swap the relay out.

And of course there are lots of connectors in there, and that car is old enough that connectors may be starting to fail.

Having a shop manual makes this sort of thing a thousand times easier because it tells you how everything is wired and where all the connecting points are.

If the fuse under the dash is bad, the dash panel lights will be out as well as the front running lights. The fuse for the tail lights is the at the top right of the panel under the dash by the driver's left foot.

If the fuse is ok, then I would suspect the bulbs next, then the ground tag, then the trailer hitch wiring connection which is usually under the kick panel under the spare tire if factory.

Are the brake and running lights part of the same bulb? If so, there are two filaments inside the bulb and one could be blown out. This would explain why the brake lights work but the running lights don't.
