From time to time all the gauges on the instrument panel cease to function. This usually seems to happen at idle/park or traveling at low speeds in a neighborhood. I've read up a lil bit and some people think this could be related to humidity/rain too.

In any case the intermittment gauges failing is accompanied by:
Check Engine light comes on
Air Bag light comes on
"No Bus" or "No bu5" shows on the odometer

Vehicle functions do not seem affected. IE: The engine still runs and so does everything else. A restart of the Jeep usually gets rid of it, but it does pop up again from time to time.

This is our first Jeep and we love it. Just bought it on a wonderful deal for $4k at 90k miles and its in great internal/external shape aside from this lil problem.

I saw a bulletin on something like this, not sure if it applies to your exact problem, 08-15-99. The cure is a repair harness that has a revised instrument cluster connector.

The problem seems to be caused by minor oxidation of bus circuit terminals at the connector.

Common issue with the 99s...

I had the same problem. My friend referred me to this site that had a lot of information about various types of cars. It was actually a very simple fix; heres the link:

I go here for all of my car questions, so hopefully it helped you! :lol2:
