I was curious to see what might be causing this problem. My girl was out revving the engine at a mustang tonight and the instrument panel just froze...nothing works, the tach, speedo, miles, trip meter, volt, oil pressure, water temp. nothing works and there is a continuous beep that happens when you pull the lights on;. Just like you hear when the car is off and the lights are left on. any help will be greatly appreciated...thanks
