I have a problem with the instrument cluster on my van locked up. The needles are stuck wether on or off at the location they were when the van was on the day it happened. The idiot lights are also on as they were except when off, there is no mileage showing nor does the transmission position indicator show at all. I cant find that the fuse is blown so at the moment Im stumped, this happened last year as well and lasted for a week before going back to normal but this has been going on for two weeks this time.

i had the same problem . Dos your van start and then shut off. If so it is a bad solder job on the cluster gages . If you check out my post from earlyer . I detailed how i fixed it . I am no car guru but research it on this sit and fixed my problem.

Nope the van works fine aside from this issue so I have no idea, I think I'll have to get a new gauge set.

Re: dodge caravan intermittent dash gauge problem

Let me format that a liitle better and repost: (BTW, I used a free
text editor call TextMorph to fix that with a couple of mouse clicks)

I came up with "No CCD Message From TCM", TCM is Transmission control
module, CCD refers to the interface that allows the instrument
cluster, body computer, engine computer, and transmission computer to
communicate.
I recently had problems with my 1998 Grand Voyager, 3.3L engine. I also
had the dead dash, intermittantly, but mainly my van either wouldn't
crank at all or would start but die if it did decided to crank. My
problem turned out to be the engine computer, one from a junkyard fixed
it. I searched the internet for info on my problem, and saved useful
info which may help you. Here's info on how the various computers work
together:
"There are a number of computers in these cars in a network, they
communicate continuously with each other over a communications bus, a
twisted pair of wires called the CCD bus. The instrument cluster, with
the odometer has a microprocessor within it as well. The cluster is
told what mileage to display by the BCM (Body Control Module) The BCM
communicates with the (PCM) power control module. This is the mother
computer located on the driver's side under the hood next to the fuse
box. The BCM also communicates with the TCM (transmission control
module) located in a similar position as the PCM under the hood on the
passenger side. In order to display the correct mileage, the BCM
(located drivers side under the dash) must get the correct info from
the PCM and the TCM. "
Another thing I learned: the dash has built-in diagnostics. Here's info
on that:
"The following is derived from the '97 factory service manual: The
instrument cluster can self test and give you some diagnostics. With
the ignition switch off, hold down the odo trip and reset buttons.
While holding these buttons down, turn the ignition switch to on and
keep holding the buttons down. Continue to hold in the buttons until
the word codE appears in the odo window, it should take about 5
seconds. If there are problems, you will get trouble codes. If there
is no problem, you will get a 999 code for end of test. When chec-0 is
displayed, the display will dim down. If brightness doesn't change
there is a problem. Codes: 110 memory fault in cluster 111
calibration fault in cluster 905 not CCD bus message from TCM, 921 odo
fault from BCM, 940 no CCD bus message from PCM. When chec-1 is
displayed the gauges will move through their calibration points. When
CHEC-2 is displayed, the odo digits will light sequentially. Chec-3 is
the PRND3L check. "
Another thing I learned is that many people have had instrument cluster
problems caused by bad solder joints on the connectors where the wire
harnesses connect to the PC board. This could be the cause of your
problem. Info on that:
Symptoms: 1. Put key in, van starts and there is no trouble. 2. Put key
in, turn key and have no power to fuel gauge, speedometer, tach,
temperature gauge, gear indicator, odometer. All the indicators in the
top panel: check engine, ABS, Alarm, etc. function properly; van will
"start" but dies the instant I let go of the key. 3. Put key in, no
gauges, same as #2, van starts and continues to run and all gauges come
to life (this is the least frequent) 4. Driving along and lose power to
the gauges. Van continues to run without problem - just don't have any
idea how fast I'm going. Sometimes the gauges come back to life while
I'm driving.
The fixes: Pound on the dash on both sides of the steering wheel at
once. Hard. Does it fix it? Good chance it's a cracked solder joint.
Info on fixing that:
"Mine would also do the dash on / dash off while driving, but as you
can see from the posts it also had the starting problem, anyway....,
back in the beginning of October I went ahead and pulled the cluster
out (very simple, maybe took 15 min), on the back of the circuit board
of the cluster where the main connector solders on to the board there
are perhaps 12 solder connections for the plug pins, people had
mentioned to look for cracked or cold solders at those locations
especially at the black wire connections (there are two) I didnt find
any cracked solders however I decided to re-solder them anyway when I
heated one of the black wire pin connections the cold solder joint was
exposed, for all intents and purposes it was barely even making
contact, it was more of a dome of solder, I finished soldering it back
up and reinstalled the cluster, to date i have not had any repeats of
either the starting or on / off of the cluster (knock on wood)."
Note: that's the combined wisdom of a bunch of people, sorry I didn't
copy their names to give credit. Hope this helps with your problem.

This is a post that i found on another site that help me . Seems there are problems with the cluster

Thats alot of good information that I will put to use tomorrow when its light out.
With my gauges what I have is this.
All of the needles are wether the van is running or not stuck at the position they were when the gauge cluster froze, so the temp needle is at the full operating temp position of half way, the gas needle shows 1/3 tank, the tach needle shows idle rev, the odometer does not light up, the trans position lights do not work, the door ajar light is on constantly as is the check engine light ( its an egr valve for the last year ). All of this is a constant regardless of driving and the idiot lights only go off when I turn off the van. I can drive the van without any issues and have to use the overhead comp to watch my fuel consumption.
The other day I pounded on the dash and the headlights would flicker so I dont want to try that again.

I just tried the diagnostics and theres no light and the gauges are still stuck, even beat on the dash some more and no luck.

Go under the hood in the PDC and try pulling the IOD fuse for like 3 minutes and then reinsert and see if that helps , this will reboot the bcm and this will sometimes fix the cluster issue , a cheap try.
