Games on instrument panels aren't working. Speedometer reads lower than actual speed, temp gage reads high, and gas gage differs. What can I do to fix this?
The gauge cluster ground is failing or is loose. It could be as simple as a loose connection in the harness, or the printed circuit might be going bad. Try jiggling wire harnesses under the dash with the engine running and see if you can get the gauges to respond.
