98 ram 2500 diesel...all the lights on the dash work just the gauges quit..if its a fuse which one??

 

Owners manual or fuse bx cover might state which one it is.

 

I don't have a manual and the covers don't say "gauges" but I have replaced most of them under the hood and in the small panel in the dashboard...all warning lights still work...mileage is blinking but working...all worked when I parked it one night, nothing next morning...thanks for the reply

 

Bad PCM, or CTM.
