My 2001 Sunfire gauges have been going out intermittently for months now. I've taken it to a shop and they couldn't determine anything. So far the following is what i've gathered personally. - All the gauges work intermittently. - Headlights so dim I cannot drive at night, but brighten when I brake. - If I put AC or heater on my gauges will go out immediately. - All my warning lights will come on as intermittent as the gauges. - Car runs and drives fine. - Check engine light stays on which has indicated a fuel system leak which new cap did not fix. Best we have come up with is a bad ground. I cleaned some grounding points and wires and the car does seem to start better, but problem persists. - New alternator - New Battery - Completely tune up I really don't want to spend more money shooting in the dark. Any ideas?

I had the same problem. Goodwrench looked at my car for 2 hours could not figure it out. Then they unpluged the body control module and plugged it back in and presto, problem solved.

sounds like your alternator. if you have a multimeter then turn on your car and turn your headlights on/ac and heater fan on high/wipers on and blinkers on. once they are all on hook the meter to the battery and if it reads less then 14 volts then the alt is bad. or you can just take it to a shop and have it tested.

Check your battery cable connections on the battery, starter, and ground. Might be dirty loose or damaged.

Polishing the lenses is a temporary fix and doesnt last long, and then its worse than it was to begin with. You can try with some plastic polish and get them the best you can or replace the headlights, There are several companies on the net that you can purchase lights from, just google Cadillac Headlights and shop around. .Make sure they are dim because of the lens and not an electrical problem.
