Instrument panel lights

97 TJ. The instrument panel lights do not work. All indicators and gauges are working. The PO says that everything was fine the day before I picked it up, but I find this a little suspect. I've checked the fuse and I've made sure it wasn't fully dimmed. I've never had a vehicle that has this old of a headlamp switch, so do the instrument panel lights come on as soon as you pull out the switch, or do you have to turn the switch all the way? Stupid questions, I know, but I'm thoroughly confused.
Ideas?

Pull out 1 notch, (P lights), Rotate the knob to the left, CCW at stop the dome will come on, turn to right, CW till dome goes out, panel lights should be the brightest. The change of the lamps is not bad there is a thread on it

Yea, that's what I thought I had to do, and it didn't work. Wouldn't it be a little unusual that all 3 lights would go out at once?

First thing I would check is the ground since all are out. If you remove the driver's side speaker cover (two screws on the end of the dash, then pull straight back) there's a ground screw for the panel lights right below the speaker. If that's not it, check the connectors.

That wire is there. I saw it connected last week when I was looking to see how difficult it would be to change the speakers.
I'm also wondering if the PO's addition of the lights on the bumper or even the change in the stereo could have done something. When I looked at the fuse box, it looked like the fuze was a different amp than what was supposed to be there. I think it's supposed to be a 10, but it was a 20 (or something like that)

Yes, it should be fuse #3 (10 amp) in the fuse block. If you have a 20 amp in there, take it out and put the proper fuse in. That circuit wiring can't handle that big of fuse (the wires will burn before the fuse blows). The wire that feeds your instrument lights as well as radio lights, and any lights in switches that come on with your headlights is orange. If anything else is spliced in like fog lights, you need to get them off that line. Even if they are just controlling a relay with it, it's on a dimmer so there would be issues with the relay if it was dimmed down.

This may be almost impossible to answer, but what's the easiest way to figure out if the fog lights are spliced in? Would a 20amp fuze suggest the fog lights are on it? Where should I put them after I've got them off that fuze (if they are on it)? Would that explain why the instrument panel lights aren't working?

Do the fog lights work, and if they do, do they still work if you pull that fuse? That will tell you if they are tied in to that circuit. It's hard to say if what they did would effect your panel lights since we don't know what they did. You may have to just trace the wires back.

That sounds unpleasant to say the least. The fog lights do work though. I'll have to find some time to pull the fuze, and let you know.

Is your 97 an Auto? - Just wondering if the PRND21 panel lights up - it's on the same circuit as the dash panel. If the PRND21 panel stays lit up when the dash panel doesn't means the fault is with the dash panel and not the circuit.
There are also lights behind the HVAC panel on the same circuit, so if the HVAC panel lights stay on when the dash lights go out, it's possible to eliminate certain things.

The HVAC panel lights may not be a very good test though as it is common for them to fail.

It's a manual. So if the climate control doesn't light up, that would mean it could be the same circuit?
