Hey all,

The past 3 or 4 days, i've been having a strange issue with my gauges.

I'll be cruising along the highway, and all of a sudden, the 'airbag' light comes on, and a second later my tachometer and speedometer quit working, just drop out. It will then stay like that for some time and then start back up again, or it stays off till i restart the jeep.

Any idea what may be causing this? it is a bit frustrating to not know how fast im going, and i assume this wont be an excuse if i get pulled over

The connector to the cluster is corroded or dirty. Sometimes gently smacking the dash fixes the problem for a while.
Here's the right way to fix it:

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.

SUBJECT:
Erratic, Intermittent Cluster Operation/Intermittent Air Bag Warning light.

OVERVIEW:
This bulletin involves installing a repair harness containing a revised instrument cluster connector.

MODELS:

1998 - 1999 (TJ) Wrangler
1998 - 1999 (XJ) Cherokee

SYMPTOM/CONDITION:
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.

DIAGNOSIS:
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.

PARTS REQUIRED:

1 05016261AA Cluster Connector Patch Harness

You can also check the solder on back of the instrument cluster the dodges are famous for doin this. Look carefully at the cluster connector and you may see hair line cracks on the solder connections, resolding the connections and that could correct the problem too
