Speedometer not working

[marronea]

My speedometer just stopped working as well as the tacometer. I don't know what happened. Is there a connection or something that could have come loose?

Let it warm up a little..... (whistle)

Actually try disconnecting your battery for a few minutes. This resets a lot of the computer controlled settings. It may just need a quick reset. However, if that does not work BCM problem?

try self-testing the cluster, checking fuses, and looking around for loose connectors/plugs.

More on the self-test can be found here. scroll down a few posts and instructions are posted.

Also, you don't mention what year your KJ is. If it's a 2002, they're known for the BCM's going bad, and random electronics stop working. Speedo and tach can go out, dome lights don't work, radio quits, no horn...etc.
