Was driving along on a beautiful day here in Texas in my '91 300E when my temperature, oil pressure, and fuel level gauges all just died.

The middle (speedometer, outside temp) and right side (tach, clock) are still working.

Any clue what caused this anybody? Is there a fuse that exclusively controls those left-side gauges that might've blown?

Thanks for any knowledge in this area as always!
