Instrument cluster panel

if flashing not a fuse need to check circuit wiring or connections for short or connection problems

Yes, it is a partial diagram. Check voltage and ground, see the fuses, not only check the fuses, check the fuse circuit for voltage. Use a test light. Some fuse circuits are hot all the time, some go hot with the key on. Also, check the ground, black wire with white tracer in diagram, should be chassis ground, check the way you would any chassis ground.
Any applicable trouble codes? As far as your gages, the pcm sends serial data to instrument cluster telling ipc what to do with gages. I can't rule out instrument cluster itself, at the moment.

A bad or lose ground ! Checking a wiring diagram would show if these thing's share a common ground . Transmission , instrument cluster lighting an the radio lights up with the instrument cluster . You can go onto youtube an check out videos on how to read a wiring diagram , how to do voltage drop testing , basic automotive electrical circuit testing . Then you could go to http://bbbind.com/free_tsb.html free wiring diagrams an test the instrument panel back lighting circuits ! You will need a DVOM - digital volt ohm meter an you will more then likely need to take parts of your instrument panel apart . Your probably better off taking your vehicle to a qualified repair shop .

Hope this helps

Check 20Amp LP Park Fuse in Underhood Fuse Block (mounted to right strut tower) Check 15Amp Tail Lic. Lamp Fuse In IP Fuse Block.

1. Use a test lead with a indicator light / led to trace power to instrument cluster lights.
2. A circuit diagram would be of assistance if you are competent to read the circuitry and symbols.

FIRST OF ALL WHAT TYPE OF VEHICLE DO YOU HAVE? IF ITS AN OLDER MODEL CHANCES ARE REMOVE SCREWS AROUND INSTRUMENT PANEL EASE OUT PANEL REPLACE THE BULBS THAT ARE DEFECTIVE. ON MOST LATE MODELS THE INSTRUMENT CLUSTER IS JUST THAT A CIRCUIT BOARD SYSTEM AND YOUR ONLY OPTION IS TO REPLACE INSTRUMENT CLUSTER. MAY BE ABLE TO GIVE YOU MORE INFO ONCE I KNOW WHAT EXACTLY YOU ARE WORKING ON YEAR, MAKE ,MODE,ANY EXTRAS

Try to remove the instrument panel and disconnect the harness to see if doing that gets rid of the blown fuse when starting the car. If it does, then the instrument panel should be replaced with another. If the fuse still blows when starting, then there is a wire shorted to ground somewhere.

Instruments and Switches Instrument Cluster Removal & Installation To Remove:

1. Remove the instrument cluster trim plate.
2. Remove the instrument cluster mounting screws.
3. Rotate the instrument cluster rearward and lift up on the top of the cluster in order to disengage the locating pins.
4. Disconnect the electrical connectors from the instrument cluster.
5. Remove the instrument cluster.

To Install:

1. Connect the electrical connectors to the instrument cluster.
2. Position the locating pins to the holes in the instrument panel.
3. Install the instrument cluster by rotating the top inward.
4. Install the mounting screws.
5. Install the trim plate.

Remove the instrument cluster. Un-plug the attached wiring harness. Lay the cluster on its face and un snap the black plastic cover over the PC board. Carefully lift the PC board off the gauge assembly. When you turn over the board, you will see four small surface-mount resistors burned and or fallen off the board. They are grouped together on one end of the board. You will need to replace them with four 120 ohm 1/2 watt resistors.

The bulb is probably loose and/or burnt out. If you are mechanically inclined you can tackle this job... This procedure is the one i use, most often it's the blue high beam indicator bulb that goes so if you want to change it while your in there.....(hint hint)
Disconnect and isolate the battery negative cable. Wait a good 2 minutes to allow for air bag deactivation...NOTE: USE CAUTION ...Lower the tilt wheel to lowest position.
Remove the cluster bezel from the instrument panel.
Remove the two screws that secure the upper mounting tabs of the instrument cluster to the underside of the instrument cluster hood formation of the instrument panel top pad.
Remove the two screws that secure the lower mounting tabs of the instrument cluster to the instrument panel structural duct.
Pull the upper mounting tabs of the instrument cluster downward, then pull the instrument cluster rearward far enough to access the instrument panel wire harness connector for the instrument cluster. Disconnect the instrument panel wire harness connector for the instrument cluster from the connector receptacle on the back of the instrument cluster housing.
Remove the instrument cluster from the instrument panel. Now do you remember which bulb it was? You can now see where the check engine light bulb is mounted. Twist and remove, install in reverse order. In some cases they are just loose or not making good ground, but after going through this just to access that lil bugger, i'd replace it.
I hope i have helped you and if you feel i have please acknowledge.
Be well and keep the cherokees alive....
