Gauges stopped working?

Hi,

I attached a copy of the wiring schematic and circled two fuses to check first. You may have already checked them, but I'm not sure.

Next, in addition to checking the fuses, confirm there is power both in and out from it. Here is a link that you may find helpful:

I had to cut the schematic into two parts to make it readable. However, I did overlap them so you can follow them easier. (pics 1 and 2)

Note that both of these fuses are located under the hood in the power distribution box.

Let me know. Also, make sure nothing has come loose under the dash where the harness plugs into the instrument cluster.

Take care,
Joe

The cluster itself is probably bad. Have seen many on this truck. The cluster needs to be sent out for repair.

The body computer uses shared information all coming from the vehicle speed sensor.
Test your computer for a speed sensor fault code. It's called a VSS. They had problems with the sensor and plastic gear also. It can shut the van off and affect the speed control also.

You may be. Under the hood is a power distribution center. You may find a problem there. The ground for both the radio and instrument panel are in the center of the dash, back behind the radio, and next to your left foot is a trim panel, there is a ground there and in the same place on the other side. If you can find out which relay or module is clicking, it may be that also. So there are 5 spots to look. And if you use a 12 volt test light and ground its clip on any good piece of steel or frame, it will light. This is a power test. If you put your test light to 12 volts, it becomes a ground check. If you find the clicking relay or module, write down the color of the wires, and let me know. Remember, when checking for grounds with a test light, the key should be off, so be careful as you may blow a fuse in one of the two fuse locations. 1. Where you already looked and 2. In the power distribution center, a black covered box, under the hood. Is this a Dodge radio?
In the power center number 2, I spoke of, there should be a couple of spare fuses and relays, so you have them. Need a 12volt test light to test for power or ground. This is the least expensive way to test an automotive circuit. And the only way, to make sure a fuse is good, and has power.

AM and FM can both be intermittent on the Alpine-built cd / radio without cassette. I've repaired a lot of them. The repair is permanent but it's definitely not a do-it-yourself repair.

The Mitsubishi-built cd / cassette combo can develop intermittent FM only; not AM. These are also a complicated repair, but once repaired, it won't ever act up again. These problems stem from automated manufacturing techniques.

Besides what ch112063 mentioned, the connector pins on the back of the instrument cluster can work loose. Soldering them to the copper circuits is an effective repair.

Check the connector pins on the back of the instrument cluster to see if they're loose. They can be soldered to the copper circuits.

Your title says "Gauges", but then you mentioned the heater blower. Did these things quit at the same time? Are they all dead all the time or does this occur at random? Do you have a factory cassette player in your radio, and do you have power windows?

Do you have a cassette player in an original radio, and do you have power windows?

Well it mostlikely one of two things, either the connection behind the gauges is loose, or the body control module has a bad connection at one of its leads, I ve experienced both of these possibilites, with my own and with a customers.
