Se prende o se apaga la iluminación???

O se mueven y dejan de moverse las agujas???

Son dos fallas diferentes, con origenes diferentes...

Es correcto...las agujas se bajan con si el jeep estuviera apagado y de repente de despiertan otra vez como si nada. la iluminacion esta ok.

Ahí va (primero teoría y luego imágenes):

Ahí vá en inglés el problema y la solución:

Here's the scoop on the guages problem I was having on my '98 TJ

Problem: While driving the Speedo and Tach would go dead and the airbag
light would come on. The shift light would aslo stop working.

Temporary Solution: One good solid wack on top of the instrument panel
would temporarily fix the problem.

Permanent Solution: This is much easier than I ever imagined. I fixed
the problem myself in about 45 minutes. I could have done it in 10
minutes if I had already known how to take the dash apart.

Heres the basic jest of the solution. The instrument cluster is a module
that plugs into the dash/frame. When removed, the instrument cluster
pulls right out, there is no wiring hanging off the back or anything.
There are connectors built into the back of the instrument cluster, the
other half of the connectors are built onto the frame that the
instrument cluster plugs into. This is the connection that is causing
the problem.

Once the instrument cluster is removed, you can see the small silver
blade type connectors protruding from the rear of the instrument cluster
in 2 different groups, one on the left and one on the right. All you
have to do to fix the connection problem is this. Take a small pair of
needle-node pliers, grab the end of each one of the silver blade type
connector and give it a 10-15 degree twist in one direction. This will
bend the connector enough to make a solid connection once the unit is
put back together. Be careful not to twist it too much so it doesnt
break and/or not go back together. Do this to all of the connectors,
there are about 20 or so. It works great, I havent had a problem with it
since.

Oh, ok, so you wanna know how to get the dash apart. No problem.

1. Locate the long thin grill cover on top of the dash that covers the
windshield defroster. It runs almost the entire lenght of the dash.
2. Work you fingers behind it between the windshield and the cover
itself and gently but firmly pull up and tward you. It will pop right
out. No screws.
3. Locate the cover that covers the lower half of the steering wheel
column down by your knees and remove it. 2 screws.
4. Next you will see a steel cover plate behind the cover you just
removed. It has 4 screws. I took it off anyway but it may not be
nessisary.
5. With these covers removed you will be able to Identify 5 screws that
hold the black Instument panel cover in place.
There are 3 across the top next to the windshield and 2 on the lower
side. Remove them and the black cover.
6. You will then be able to see 4 screws that hold the instrument
cluster in place. Remove them.
7. The instrument cluster lifts right out.

You can perform this entire procedure, repair the connection, and
reassemble your cool jeep in about 15 minutes. All thats needed is a
short cross point screwdriver.

Hope this helps, it certainly saved me one of those grewling trips to
the dealer.

DATE: May 21, 1999

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®, 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
1 04856975 Electric Contact Cleaner
2 04778570 Heat Shrink Tubing


Y ésta es un guía con imágenes para solucionarlo...

Y solo limpia los conectores con un cottonete con alcohol o limpiador de piezas electrónicas, y vuelve a armar en orden inverso...

[Abel4X4]

Ahh!!!, y aprovecha para cambiar algún foquito fundido del tablero, ya sea de la iluminación o de algún marcador...

Postea resultados, y guarden esta información, es de mucha utilidad, yo batallé mucho para encontrarla...

Abel,

Te sacaste un 10 con la explicacion y las fotos gracias por tu tiempo.!!!
