If just the instrument cluster is dark, I would look for a wiring problem. If none of the dash lights work, could be a dimmer switch or fuse problem.

This will help.

Thanks.

Look under the dash and check all the connectors in the harness.Finally check the fuses , the dash light section.
If none of these works then the cluster instrument board must be taken out and checked.

Sounds like you may have a blown fuse for your instrument panel assembly, open your fuse box and read on the cover the location of your instrument panel fuse pull it out with the fuse puller and see if its blown it its blown replace the fuse with the SAME amperage fuse you removed, your gauges should work again, if the fuse is good check the plug going into the back of the cluster and make sure its secure and clean, if your fuse is blown and you replace it with another fuse and it right blows again theres a short in the wiring for your instrument cluster circuit and further diagnosing will be required to locate and fix a potential short....

sounds like an open to the lights in the instrument panel, if the lights work in the radio, ac panel, etc.

Or, all the bulbs burnt out at once (unlikely).

Maybe the harness to the instrument panel is loose, but only is accessible after removing the dash board.

Check that your tailights/parking lights are working (not the headlights) as this fuse and relay feeds all the instument lights too.... Fuse 15amp TAIL & Tailight Relay

If not then check:
The rheostat (also known as the dimmer switch) may be faulty
as it controls all the illumination of all the backlight bulbs and other dimable switches/indicators.

In general bulbs all together draw a fair amount of current so it is possible that the wiring or ground at the major supply junction feeders has failed but that is a less common problem.

So check the rheostat dimmer wiring area first as all illumination power goes through it.

There is further simple testing we can do with the three wires at the rheostat you can check the entire illumination system.
If you jumper the white/blk to the white/blk all the illumination lights should come on (that means the rheostat is bad).

Or use a voltmeter and measure the green rehostat wire to ground it should be 12volts (if not time to check the fuse, relay and wiring)

If not then finally declare the instrument panel faulty (like burned up circuit board trace).

Note of interest: the rheostat also controls (dims) other switches not associated with the instrument cluster such as the cigarette lighter bulb and hazard switch and radio player and A/C control switch. So if those are dimming but not the instrument panel backlights then yes the instrument cluster needs fixing or a very close wiring inspection.
