94 Bonneville dashboard problems

The tachmeter, oil pressure gage, voltage meter, coolant meter along with the gas gage doesn't work. It stopped all of a sudden. The only thing that works is my speedometer. What is causing this to happen, and what can I do to resolve this situation.

i do believe that all of the stuff that stopped working were electricial and the only reason your spedo works is becasue it is drivin by a cable i do believe im not 100% sure

Check your fuses, I believe your guages are all controlled through the same fuse. The speedo is electronic also, but it's on a different fuse circuit.

I had the same thing happen to my 94 SSE two weeks ago. Had to replace the whole instrument panel(cluster), found one on ebay for 20 bucks. Found out that there is a processor located on the circuit board mounted on the instrument panel goes bad. Easy to change, just takes a little patience.
