Chrysler Repair: 97 Grand Voyager w/ dead instrument cluster, digital odometer, inner fender

Question
Last week while on a roadtrip my 97 Grand Voyager's instrument cluster went dead. The tach & speed both are at zero and the temp & fuel just froze in place. Also, the digital odometer & gear indicator don't work as well. All accessories are working fine.

Any ideas on how to fix this?


Thanks for your help

Hi Darrin,
There are 5 wires on the instrument cluster plug. One is pink wire that is hot all the time coming from fuse 28 in the power distribution center under the hood near the battery. So check that fuse carefully for a subtle break in the internal wire. Also check fuse 2 in the junction block (fuse box) under the dash which sends power to the cluster on a red/white wire via the ignition switch. Then there is a black/light green wire that is the ground return to the battery that is connected to a ground point you will either find just in front of the driver side door opening on the body metal, or on the floor nearby to that or the floor under the dash near the firewall. That wire could be loose which would cause the circuit required for current to flow back to the battery to be "open". Finally there are two digital data carrying wires that are black/white and violet/brown that are connected to the big plug at the power controller under the hood on the driver side inner fender next to the box where fuse 28 is located. I might be able to tell you how to find the pins on that plug to verify continuity between the cluster and the controller if you told me which engine you have.
If you verify the fuses, ground, and data wires, then the cluster may have failed, but I would not replace that until I proved I had power, a ground, and data connections.
