Q: My instrument cluster is not working properly! Help!

asked by on August 13, 2016

All of the gauges on my cluster are not working as they should in my 2003 Chevy Cavalier. The fuel and temperature gauges do not work at all, and the speedometer and RPM gauge work when they feel like it, oftentimes sticking or just not working at all. All of the warning lights seem to work just fine. How do I figure out if this is an electrical issue or an issue with the cluster itself? If I can avoid a pricey repair and fix this at home by disconnecting and reconnecting certain cables or something of that nature, please let me know. I'm afraid I'll get a speeding ticket or worse. Thanks!

My car has 107515 miles.
My car has an automatic transmission.

Check that all fuses are good. You can try removing the electrical connector on the back of the instrument cluster and plugging it back in. Odds are, the amplifier inside the gauge cluster has failed of has poor connection. It would have to be disassembled and repaired or replaced.

The smoke could be burning oil. If the smoke occurs just at start up, the source could be leaking valve stem oil seals. If the smoke continues but is mainly white, that could signify an internal coolant leak.
