My cars display cluster stopped working. Headlights turn on when turning the car is on, even when the knob of the headlights are on the off position as well. All lights work inside the car. Tested the fuse for the display cluster and its working. Battery is new. Has anyone had this problem with a Mercedes c230 kompressor. Does anyone here have the wire diagram for this vehicle. Thank you.

One more thing the only icon that is displayed on the the display cluster is the highbeam icon. Even when the car is off the high beam icon is flashing. But tachometer not working the display lights up but turns off when the car is turned off.
