check your ground wires

If you have a pigtail for plugging in a trailer, trace back from the end to where it joins the harness. the joins tend to corrode and short.

It's not going to solve you root problem but it might give you a little peace of mind problemwise. My service manual (a '92) shows that the Park/tail lamp fuse (#15/15amp) provides power (via the headlight switch) to the instrument cluster. Blowing this fuse will result in their loss. A confirmation of this would be to check fuse #19/5amp which is downline and protects the cluster, if it's still good then your problem is in the Part/tail lamp circuit. Solve that problem and the other will be repair as well. Allow me time to decipher the hyrogliphics on the park/tail lamp circuit and I may be able to make some suggestions, however as the earlier repliers state it is most likely a ground fault problem and trailer wiring faults are the #1 cause!
Good Luck

So i checked my trailer towing wiring and it wasn't the problem but not sure where to start cause major heading not being able to drive the jeep at night.
