While driving into work this morning everything in my Speedometer area when black. All back lighting went out, clock went out, trip ometer reset...this all happened while there was a consistant 4 or 5 beeps. Then it all came back on however it seemed to take a few minutes for warning lamps to reset, like the seat belt warning lamp even though my seat belt was secure. During this I noticed no difference in the engine or any of the other controls such as the radio or AC. The rest of the drive was fine; just had to reset the time on the clock. Any idea of what might be causing this?
