Put both hands on the cluster and push it in. It probably has come a little loose. Mines did that to me once. It turned out to be that.
I give mine a nice whack on the top-right of the cluster every now and again when they cut out, but in my case it is only speed/tach/odometer that go dead. Fuel, temp, pressure continue to read normally. It actually happens a lot. Sounds like maybe a different issue though.
my 99 tj has the same issue, but only the temp and battery gauge work. ive changed all fuses, put new ground cables in. tried the whole squeeze the pins on the back of the cluster and got nothin. even put a new cluster in it and it still wont work. im stuck
Not sure if you are experiencing the whole instrument panel problem of tach and speedometer dropping and airbag light coming on but this is from my original bulletin after complaining to Jeep over and over again! This is a common problem with the Jeep wranglers that causes the gauges to have intermittent operation. Jeep has issued 2 TSBs about it. 08-15-99 is the latest and basically states that the male terminals on the cluster get corroded. There is a cleaning procedure and some small parts to get to correct the problem.

THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN NUMBER 08-20-98 REV. A, DATED OCTOBER 2, 1998, WHICH SHOULD BE REMOVED FROM YOUR FILES AND NOTED IN THE BOUND TECHNICAL SERVICE BULLETIN BOOK, PUBLICATION NUMBER 81-699-99003. THIS IS A COMPLETE REVISION TO THE PROCEDURE.
Erratic, Intermittent Cluster Operation/Intermittent Air Bag Warning light.
This bulletin involves installing a repair harness containing a revised instrument cluster connector.
Some vehicles may exhibit an intermittent illumination of the air bag warning light or an intermittent tachometer or speedometer drop out. An Airbag Electronic Control Module (AECM) fault code - "No Cluster CCD BUS" message will be present.
Using the DRB III(R), read and record all active and stored fault codes in the AECM. This condition is caused by minor oxidation of the BUS circuit terminals at the instrument cluster connector. Electrical terminals will show signs of oxidation, which will appear as darkened lines or marks on the cluster male terminals. These often appear as gray or black marks rather than the appearance of oxidation or corrosion usually associated with higher current carrying circuits. This condition will set a "NO CLUSTER CCD BUS" message. The fault code will usually be stored and not active. THIS TECHNICAL SERVICE BULLETIN WILL NOT ADDRESS FUEL OR OIL PRESSURE GAUGE ISSUES. If this fault code is present, either active or stored perform the Repair Procedure.
