Gauge Cluster Light Issues

[vindicated]

So here's a weird issue. The gauge cluster lights do not work, but all the instruments work as do the warning lights. Also, the lights on my HVAC controls are out too. I have checked all the fuses and determined nothing is blown.

I have pulled the dash and looked for loose grounds, but honestly, it was a cluster **** of wires back there, and I have no idea what I am looking for. I was jiggling wires around and my airbag light started flashing, so I quit while I was ahead.

Anyone have any ideas what to check next? I am at a loss.

DId you check the bulbs? I think they twist and pull out.

Also, which HVAC control do you have? It is the one with dials? I might have one laying around, if I didn't throw it away a few years ago.

Yeah, the dial knobs. I didn't check the bulbs which sounds stupid, but I thought it was weird 2 different spots went out at the same time and that it couldn't be the bulbs.

Here's another weird hint. When I would turn on the blower to 4, the dash lights would come back on. Eventually though they just stopped coming on all together.

I haven't dug into a TJ in awhile, but I had a similar problem and it was the blower motor resistor.

Wouldn't that keep the motor from blowing at certain speeds or at all? I can try that though!

Have you tried reading Ohms on the ground circuit? A lot easier than tracing wires..

Kinda what I said regarding I don't even know how to identify the ground circuit. Like no joke, I don't do electrical stuff. I guess I would need a book at this point.

But thanks everyone!

My bad, I misunderstood what you mean. Thought you just couldn't trace the wire, but assumed you knew what was what..

No worries thanks for the help!
