Hope someone can point me in the right direction on how to troubleshoot instrument cluster. Today, while starting my drive home from work, I had no speedometer, temp gauge, oil pressure gauge, or tach for about half the trip (10 miles). Then, all of a sudden, all the needles of all gauges came to life and landed in their normal positions. What could cause this. Within the first 300-500 feet of my trip, a buzzer sounded momentarily and then the gauges all stopped as if the key had been turned off. Any Clues?
