Speedometer/Odometer Not working

I have a 1998 Cherokee Sport with the 4.0 I6, and the speedometer and odometer don't work, but the other gauges do. A mechanic said I need the complete gauge cluster replaced, but I'm wondering if it could be just a cable. Can anyone give me some insight?

Check the ground wires on the passenger side of the engine block before you go and replace the gauges. There should be a stud with a nut on it right behind the distributor. Take the wires off, clean the contacts with some sand paper and brake cleaner. It's worth a shot.

Also check the connections behind the gauge cluster, possibly it got disconnected

I suppose I should've put this in the description but often forget. The speedometer works 1 out of a 100 times, and its always when I'm coming to a stop from faster than 25 mph.

I would definitely check those grounds. Just fixed mine yesterday. Speedometer, odometer, and fuel gauge wouldn't work. They also caused some other problems.

Could it also be a gauge cluster issue?

Yes, My temp gauge quit working cause the plastic cracked around the mounting screws which was the connection between the cluster circuit and the gauge

Mine still isn't fixed. I replaced the gauge cluster, because I found a cheap one on ebay, but that didn't do anything. I took the ground off again and cleaned it all up, but still no luck. It has to be my VSS, or at least I'm hoping. I need to buy a replacement. Mine just doesn't look right the way all of that is going into the transfer case. Can someone snap a few pics of yours for me to compare?

Well my brothers 99 XJ so far:

I've replace the cluster, cleaned and inspected all the connections, cleaned the ground wire and added a second ground wire to be sure.

I'm at a lose.

Speedo and trip meter don't work and the Gas gauge reads full or empty randomly as you drive own the street.

Try the speed sensor in/attached to your transmission.

Examine the Vehicle Speed Sensor (VSS) on the Transfer Case (4WD) or on the transmission rear housing (2WD).

See if it's secure.

Examine the electrical connector and wiring on the VSS, and as far towards the front as you can see. See if it's secure/free from chafing. If it is, remove the connector and see if the pins and pin cavities are free from corrosion.

Do this Instrument Cluster Actuator Test. It will tell you if your MPH readout and Odometer readout work. If they don't work, the Instrument Cluster is bad.

Instrument Cluster Actuator Test

(1) Begin the test with the ignition switch in the Off position.

(2) Depress the trip odometer reset button.

(3) While holding the trip odometer reset button depressed, turn the ignition switch to the On (RUN) position, but do not start the engine.

(4) Release the trip odometer reset button.

(5) The gauges should cycle through their ranges, stopping at intermediate readings, going up and going down, at two second intervals. The indicator lamps should cycle on and off.

(6) 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 on the CCD data bus during the test.
