Q: tachometer.speedometer temp gauge not working

asked by on

wife turned on a/c then problem started checked IG fuse it is ok. the speed and tach stay zero the temp maxes out on a cold engine when started. everything else, lites and indicators work on gauge cluster

My car has 195000 miles.
My car has an automatic transmission.

If cluster fuses are good, check/clean the battery ground, bot the terminal and where the ground cable connects to the chassis. If that doesn’t help, then you have a bad instrument cluster and it will have to be replaced.
