I have a 2002 Dodge Caravan with instrument cluster issues (gauges don't work) there is no communication with the instrument cluster, I have tried replacing the cluster, the BCM, removing Fuse box and cleaning all connections and terminals and used dielectric grease on all connections.I tried the speedometer Reset procedure and no codes, flashing lights or anything at all. Do you have any ideas as to why there is no communication with the instrument cluster? I have also disconnected the battery to try to reset the computer, checked fuses still nothing.

You may have a problem in the power control module and check that the fuse voltage is ok, unfortunately there is very little info on fault finding this particular problem, I see there is a BUS line is there any set fault codes?

Check fuses for d gauges first as it may be the cluster is bad and needs rebuilding. The tcm controls the transmission also check for rubbed through wires on transmission might have a broken trans mount. Unplug trans mount and pucheck for corrosion, put dielectric compound and reassemble. If stuck in 2nd gear get back to us because you may have to fix one of the connections. Finally check battery for condition including load test. See pic for location

BCM is good we had it tested. They said the BOS was not registering anything. Checked all fuses. Changed out insturment panel still does not work. Fuel gauge out, speedometer not working, temp gauge out, rpms are fine, mileage not changing. Rear wipers out, ac/heat blows does not get hot or cold. Please help mechanics are baffled.

The body control module is what controls the dash illumination and gauges, I dont know what these people are talking about, the bcm checks out ok.

Doesnt that prove there is something wrong with it, it either that or the cluster and you said you've replaced that, or the connection from the cluster to the harnass.

Three fuses, must be ok, check them using a test light or voltmeter to make sure you have voltage on boyh sides of the fuse, with the cluster lights turned on.
Under the hood in the power distribution center, the lid has information, fuse 28 is a 10 amp. Inside on the left side under the dash are two, a 10 amp number 2 and a 20 amp number 6. I believe. Thanks and good luck, do the part numbers match? The pink wire at the cluster should have power with the BCM plugged in and the fuse being ok. It may need a scanner to reset it also, check both those fuse locations, all 3 fuses. Good luck

After looking over the wiring diagram for you car I would say the body control module is bad. See the body control module controls the power to those and a few other things.

Possible options would be to check the fuse inside the car underneath the steering wheel area, there is one for the gauges, and if that isn't the problem, it's very likely the speed sensor that is malfunctioning.

Nice xxrawrxx, one more thing to add to my firends comment, the body control module if all else fails will be the culprit. There are several possibilities here

Start by checking under the dash. Make sure the wiring harness to the cluster is tight and connected. If that is good, you may have a bad cluster. Power will need to be checked to the cluster, ground as well.

Read the guide below on using a meter for testing

The wiring diagrams for the instrument cluster are attached below

All dash gauges, speedo and PRNDL are inop. Electrical connectors, fuses and relays under dash and under hood have been checked. Dash Cluster has been replaced. Body computer under dash electrical connectors have been checked. On occasion the cluster will come on at start up and operate for a short time or possibly all day, with 3-4 restarts. Most of the time cluster is in-op 90 % of the time. Could this be a corroded ground connection?

Any help you provide would be greatly appreciated. I was a certified auto technician years ago and I am currently on disability.
