The Gauges on my instrument panel will just stop functioning for about 30 seconds every time I drive the car. Only 37,000 miles on it and it started about 500 miles ago. It seems to do it more often when the headlights are on. Last night for the first time, while the headlights were on, the whole instrument panel went black for almost a whole minute, and then came back on. It usually happens withing the first few minutes after starting the car and then I don't usually have anymore issues with it until I stop the engine and then start it again, at which time the gauges will stop functioning for a short time and then work again. I don't have any idea where to start with this problem or how to take it into a repair shop without getting completely ripped off. Any suggestions?
