instrument cluster problem
 

I was recently driving my 1987 300E and a buzzing sound stated coming from the instrument cluster and the fuel, oil pressure, tachometer, and temperature gauges stopped working. The speedometer is still working. The car is not driving any different. Any help is appreciated.

Thank you

Answer
 

the buzzing is typically a ground issue, back-feeding through a relay.





Have a great day.

your fuse is out.

Battlecat714 is right about the fuse.

Don't be fooled if the fuse looks OK. They corrode and crack.
