98 TJ gauges quit working

So once in a while my speedo, tac, and other gauges would not work and the airbag light would come on. But all I had to do is turn off the key and restart and everything went back to normal. Now they have quit completely and won't come back on. So I really have to idea of miles driven, ie: gas left, speed, temp, etc.
Where do I start. Doubt it's fuse related, but....any help?

No you will have to remove the cover over the driverside speaker. The ground wire should be on one of the screws holding the speaker in place

Not uncommon. There is an issue with receptacle for the instrument panel. Jeep has a fix for it but you can likely just take out the panel and clean the connections. It plugs in as an assembly. The panel that runs across the top of the dash the length of the dash is just clipped in. Lift gently on one end and it will disengage, repeat the length of it and it will come out. Remove the four screws that retain the panel under steering column. There are just a few screws on the top and front of the instrument cluster that hold it in. Once the screws are out just pull gently and it will unplug from the connector. I had to do this a couple of times over the years but it doesn't cost me anything. Just part of owning an old Jeep.

Those ground connections were clean and secure, so I played around with the all the wires and connections I could find to no avail. Then I pulled the headlight knob and - voila! Back to working for now and now I know the quick fix. Guess I'll have to eventually pull that panel and clean it like suggested.

Welcome to the group! My dash hasn't worked for a while now haha. It's either a PCM going bad, a bad ground or a bad connector behind the dash. Google search for the connector fix and the service bulletin that Jeep issued for the parts to fix it.

Is this switch stock or added

I found a yellow wire that appears to come from a stock wiring bundle that goes to a tiny toggle switch mounted top right of fuse box. Can't find anything it controls. Does any other 98ish TJ havve this?

This is a common problem that is usually caused by a bad connection in one of the two instrument cluster connections behind the cluster. My '97 had the same issue. The fix I did was to use needle nose pliers to slightly tweak the male pins in the connections so they fit more tightly which permanently fixed the issue.

Here's a website that may help... TJ Jeep Problem with Instrument Guages.

When you have a choice, buy American.
