Q: gages on dash not accurate on 2005 Chevrolet Cavalier

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The gages on my dash are not accurate, My temperature gage points at the five miles an hour mark. Which would be about 600 degrees. My car is not givving any other indicator of over heating or any other problem. It started a couple weeks ago and has gotten worse every day.

Your temperature sending unit on the engine is likely reading out of range, or you may have shorted wiring. The key here is that you are not experiencing overheating. Conversely, you could have a faulty gauge. But your issue lies most likely with the sending unit.
This sounds like a faulty temperature sending unit or sensor, but GM products do have issues with their instrument clusters. Are any of the other gauges or the speedometer reading abnormally?
This is very common on the 03-06 GMs. The cause is the motors behind the gauges are failing, they all go out eventually. You can get it repaired here - www.drspeedometer.com and there's a DIY guide here - www.howtorepairmyinstrumentcluster.com
