Tj cluster problems

I Have a 2000 tj. Cluster lights work. Fuel tach, speedo, oil, volt, temp donít work. What I did so far:

Regrounded both cluster clip grounds.
Adjusted pins on cluster
Cleaned main ground on block
Checked fuses
Beat on my dash
Checked circuit board

Extremely frustrated

Any help would be much appreciated

Chris

I had this exact issue a month ago. Check EVERY fuse in the jeep behind the glove box. They areas really small, so test with a multimeter. Sometimes they are hard typo troppo they are toast.

Also odometer not working. Would think itís a common problem since all gauges are acting in sync.
Checked all
Fuses no luck

When the indicator lamps work but the gauges don't, the most likely cause is a bad fused battery supply to the cluster -- C2 (blue connector) pin 9 (PK/WT) should have a constant 12.6v/battery voltage present.

Power for the instrument cluster fused B+ input comes from PDC fuse 25 (10a), passes through connector C108 pin 12, then connector C203 pin B7, then on into the cluster connector C2. If PDC fuse 25 is bad, you'll also notice the under hood light and your dome light will be inoperative.

On c2 pins 9 and 12 have 12v(pink and white wire and the blue and white wire). Fuse 25 is good dome lights work.

Thank you for the help.

Anymore ideas, I’ll try anything

Hold the odometer trip reset button in while you turn the ignition switch from OFF to ON, do not start the engine, and release the button about three seconds after turning the ignition on. The instrument cluster should run through a self check as shown in the attachment where all the gauges will move to various positions and the odometer display will run from all zeros to all nines.

Does the cluster pass the self check?

Did the odometer display come on and cycle through along with the other lights or did it stay completely off along with the gauges?

Are the 97 and 2000 clusters(clips) the same.
I can take mine to my brothers and see if it works in his Jeep.

A) Did the odometer display come on and cycle through along with the other lights or
B) did it stay completely off along with the gauges?
C) If neither of the above are true, please describe in detail what it did.

The plugs on the '97 and '00 are pinned the same, but if your brother's Jeep doesn't have SKIM then installing a cluster that is used to seeing SKIM may cause an issue with the other Jeep.

A. Never came on
B. It stayed off with the gauges
C. Once I let go of the odometer reset the cluster lights came on including cruise light. Then they went off and came back on again.

The cluster is acting like it's not actually getting power from C1 pin 9, or the cluster is burned out. I'd try slightly twisting the C1 #9 pin so that it has a better chance of making a good connection with the plug terminal, or try pushing inward on the PK/WT wire at a slight angle when you switch the ignition on to see if the odometer and gauges respond.

Cluster Update: jeep tj 2000 cluster dead

I swapped my cluster(2000) with another jeep(1998) and mine didn’t work in the 98, but the 98 worked fine in my jeep(2000). So the wiring in my Jeep is fine. I took the cluster apart and bench tested it on the circuit board to make sure power was passing through the clip as on the pins on the board . Which it was. Somewhere on the circuit board lies the problem. Any suggestions?
