No lights work on instrutment panel

I assume you mean the Tachometer stopped working. What year, make, model, is the car and what engine and transmission does the car have and is it a analog or digital dashboard?

Hello
The porblem under discussion here is not related with my expertise. Please get helped from any other. OK.

You're welcome. I would try that harness repair first. It has fixed a lot of Wranglers for me. It is easy to do and relatively inexpensive. Let me know how it works if you do the repair

i have seen this before its the igntion switch . on the lock and key but the switch its self wich is located under the plastic cover on the steering colume

Sounds like a blown fuse....go through them and see which one is blown or check your owners manual..it will tell you what fuse is used for what and will save you on the guess work.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/matthew_d24b835e574ef6ca

there is a short in the wire going from the gauge to the tank. ck the wiring under the truck from the tank going forward, and ck if anything looks like its rubbing on the wiring harness.

Check transfer case wiring, possible loose wiring/open circuit. If your other lights in dashboard work such brake light, seat belt lights, engine light than it is not a fuse. raise all for tires from the ground and engage the four wheel drive remember to have in neutral and put in gear either 4L or 4H and see if the wheels in front move.

sounds like your ignition switch going bad

its probably a blown fuse
