All my gauges just quit working. car still runs fine. they done this 2 or 3 times but would always start again. this time have not come back on. turn signals and dash lights work just no gauges.
At the moment, your instrument cluster maybe faulty? Due the basic tests, try to be sure. Check for applicable trouble codes relating to instrument cluster--pcm--communication codes. Some of the national brand auto stores in this country may check codes for free, if there are any.
Check voltage and ground circuits for the instrument cluster. The sending units for gages are wired to pcm then the pcm sends serial data to instrument cluster telling instrument cluster what to do with gages. If you want to check gage sending units, that's ok.
If you have a scanner that can communicate with instrument cluster, you can get instrument cluster to do a self-test. The self-test, the instrument cluster will turn warning lamps on and off, sweep gages w/o outside data input. The instrument is considered good, if it passes that test, if not, the instrument cluster is considered faulty.
