My tachometer, gas, temp and oil pressure gauges all stopped working a couple of days ago although my speedometer, clock and economy meter are still working. Since the group of gauges went out at the same I figured it had to be a common fuse or relay. I checked all the fuses and they look fine so it must be a relay – right???

If anyone has any experience with this, I could really use the help. Thanks

 

Similar problem my 1988 SEL all dash gages stopped working But the turn indicators and horn ok,

 

You need to pull the cluster/ instrument pack.

Make sure all the wires are all making good contact. There are two relays directly behind the cluster, one os for the instrument lighting, the other for the gauges themselves.
