Cluster fuse blows out

In all probability you put the bulbs in reverse polarity blowing park light fuse.. this will also stop the dash operating correctly

Gauges have their own fuse. Under dash fuse panel. If it keeps blowing, you have a short to the power wire.

a fuse blew.
this car has an electronic dash cluster. (with brain)
first is fuses. (check them first) (2 of them)
second is scan it. scan the PCM for DTC error !

if rpm dies, for sensors the engine dies...
The PCM runs spark and injection off 2 sensor and RPM
if they die so does spark and injection.
the cluster has self test mode, try that first?
this proves the cluster is ok.
this is covered in the FSM for your JEEP

the WJ jeep
Chapter 8J covers all this.. to great details.
page 8
fuse 17 and 22 must be good. JB box, cab.

The instrument cluster actuator test will put the
instrument cluster into its self-diagnostic mode. In
this mode the instrument cluster can perform a selfdiagnostic
test that will confirm that the instrument
cluster circuitry, the gauges, the PCI data bus message
controlled indicators, and the electro-luminescent
illumination lamp (if equipped) are capable of
operating as designed. During the actuator test the
instrument cluster circuitry will sweep each of the
gauge needles across the gauge faces, illuminate each
of the segments in the Vacuum-Fluorescent Display
(VFD), turn all of the PCI data bus message-controlled
indicators on and off again, and turn the electro-
luminescent illumination lamp (if equipped) on
and off again.
Successful completion of the actuator test will confirm
that the instrument cluster is operational. However,
there may still be a problem with the PCI data
bus, the Powertrain Control Module, the Airbag Control
Module (ACM), the Body Control Module (BCM),
the Controller Anti-lock Brake (CAB), the Sentry Key
Immobilizer Module (SKIM), or the inputs to one of
these electronic control modules. Use a DRBIIIt scan
tool to diagnose these components. Refer to the
appropriate diagnostic information.
If an individual indicator lamp or the electro-luminescent
illumination lamp do not illuminate during
the actuator test, the instrument cluster should be
removed. However, check that the incandescent lamp
bulb is not faulty, that the bulb holder is properly
installed on the instrument cluster electronic circuit
board, or that the electro-luminescent lamp pigtail
wire connector is properly connected to the instrument
cluster electronic circuit board before considering
instrument cluster replacement. If the bulb and
bulb holder, or the electro-luminescent lamp connection
check OK, replace the faulty instrument cluster
unit.
(1) Begin the test with the ignition switch in the
Off position.
(2) Depress the odometer/trip odometer switch button.
(3) While still holding the odometer/trip odometer
switch button depressed, turn the ignition switch to
the On position, but do not start the engine.
(4) Release the odometer/trip odometer switch button.
(5) The instrument cluster will automatically
begin the actuator test sequence, as follows:
(a) The cluster will turn on, then off again each
of the PCI data bus message controlled indicators
(except Airbag) to confirm the functionality of the
indicator and the cluster control circuitry:
(b) The cluster will sweep the needles for each of
the gauges from minimum to maximum and back
to minimum to confirm the functionality of the
gauge and the cluster control circuitry:
(c) Only on models with a premium version of
the cluster, the cluster will illuminate the electroluminescent
lamp and turn it off again to confirm
the functionality of the lamp and the cluster control
circuitry.
(d) The cluster will sequentially step the odometer/
trip odometer VFD display from all zeros
(000000) through all nines (999999) to confirm the
functionality of all VFD segments and their control
circuitry, then display the software version number,
followed by "DONE".
(6) The actuator test is now completed. The instrument
cluster will automatically exit the self-diagnostic
mode and return to normal operation at the
completion of the test, if the ignition switch is turned
to the Off position during the test, or if a vehicle
speed message indicating that the vehicle is moving
is received from the PCM over the PCI data bus during
the test.
(7) Go back to Step 1 to repeat the test, if
required

if this passes and fuses are good
then you may have DTC errors scanned
if you scan it and you see comminications error from PCM to cluster, well that be it. ... and am not going into THAT>here.

This solution will be of great help to you,even in the case of future or other dashboard problems;
Instrument cluster consists of electronic analog gauges, various warning lights, and optional tachometer. Vehicles equipped with tachometer have an electronic vacuum fluorescent transmission range indicator (PRND3L),odometer and trip odometer display. Vehicles without tachometer are equipped with a cable-operated transmission range indicator.
Instrument cluster is equipped with the following warning lights:
Battery voltage.
Cruise (speed control).
Door ajar.
Fasten seat belt.
Lift gate ajar.
Low fuel level.
Low windshield and washer level.
Traction Control.
The Body Control Module (BCM), which receives input from various sensors, sends display information to instrument cluster and operates gauges. Instrument cluster incorporates a self-test diagnostic feature to identify electronic problems. BCM, Powertrain Control Module (PCM), and Transmission Control Module (TCM) are continuously monitored by the diagnostic system.

SELF-DIAGNOSTICS
With ignition off, press and hold TRIP and RESET buttons while turning ignition switch to ON position. Continue to hold TRIP and RESET buttons until odometer window displays CODE (approximately 5 seconds). If problem exists, system will display diagnostic trouble codes. See DIAGNOSTIC CODE CHART table. If no problem exists, Code 999 (end test) will be displayed.
DIAGNOSTIC CODE CHART
CodeDescription
110.......Cluster Memory Fault
111.......Cluster Calibration Fault
905.......No CCD Bus Message From TCM
921.......Odometer Fault From BCM
940.......No CCD Bus Message From PCM

After diagnostic code display ends, instrument cluster will go into each of the following tests in order:
Dim test.
Calibration test.
Odometer segment test.
Electronic Transmission Range indicator segment test.
Dim Test
CHEC-0 will be displayed in odometer window. Instrument cluster will dim Vacuum Florescent (VF) display. If VF displays do not dim, a problem in instrument cluster exists. See BODY CONTROL COMPUTER TESTS in BODY CONTROL COMPUTER article.
Calibration Test
CHEC-1 will be displayed in odometer window. Each of instrument cluster gauges will move sequentially through each calibration point. See GAUGE CALIBRATIONS table. If gauge needle is not calibrated properly, a problem in instrument cluster exists.

Odometer Segment Test
CHEC-2 will be displayed in odometer window. Each segment of odometer will light sequentially. If any segment does not light, replace instrument cluster.
Electronic Transmission Range Indicator Segment Test
CHEC-3 will be displayed in odometer window. Each segment of electronic transmission range indicator will light sequentially. If any segment does not light, replace instrument cluster.

The "cluster" means all of the things you see under the plastic cover in front of the driver, the 'gauges'. The term is a reference to the 'instrument cluster' including speedometer, tachometer, fuel gauge, idiot lights, temperature gauge, everything.
Get a second independent opinion since this is very unusual. Most likely you have a blown fuse.

Does the odometer work?I would start by checking the fuses.

check for an instrument cluster fuse in the fuse panel if it's good you will have to pull the cluster out and change the lights behind the gauges

My gas guage, speed odometer and tempiture does not work
The speed odometre is reading 9999999 what should i do

Have the computer checked

hello,good day,maybe your cluster nearly damage,send to your dealer,they have a testing procedure(simulation all the gauges), to determine if your cluster is defective,ty
