I am having a problem with my instrument cluster. All the gauges work fine, but when I turn on the headlights they mess up and all the lights behind the cluster light up (parking brake, service engine, etc.). If I have the rheostat switch turned all the way down and the headlights on, the gauges are fine. But with the rheostat switch all the way up and the headlights on, the gauges go wild. Does anyone have any ideas about what could be wrong or how to fix it? I tried a new rheostat switch, but that didn't help.
