Expert:  Amedee replied 6 years ago.
So is this fuse that blows a separate issue? Are the gauges inoperative all of the time regardless of the fuse or not?

I gress the fuse is separate issue. the gauges are off all the time. the fuse does not affect gauges another thing thats not working is windsheld wipers they stop the same time as gauges

IT sounds to me like you just have a bad module causing this problem.
Test the BUS volts at the diagnostic connector under the dash. Pin 3 and 11 should have 2.5 volts each. If the voltage is not present, clip the bus wires at the cluster and check the voltage coming out of the cluster. It should be putting out 2.5 volts, it is the source of the voltage. If the voltage is present coming out of the cluster, start unplugging modules one at a time to see which modules are taking the bus down.

You can also run a self test on the cluster to see if it will respond. Start with the key in the off position. Hold down the trip and the reset buttons. Turn the key to the "on" position. Hold the buttons in until the word "CHEC" appears in the odometer display. After that the dash gauges should sweep and all the lights should turn on and off.

Potential Causes:
Cluster Assembly
Module — On bus
