Re: 94 regal speedometer and tach quit working
Well, like I said you would need an OBD I scan tool....if you can read speed and tach data, it's either a cluster, connection, or wiring problem...
I found a wiring diagram....apparently your cluster is made up of two parts....the cluster and auxiliary gages cluster which has your coolant and fuel gage, and "low fuel" indicator....
Did you check your 15a cluster fuse(this powers the tach and speedometer).....the ground for both of these is the same ground for the fuel gage, so the ground is ok....however there is a connection inside the instrument cluster that may be bad....
