will dash cluster being out cause car wide problems

What is your question?

2006 Mercedes s55 amg after replacing the accessorie belt the dash lights went out as well as the steringnwheeel buttons and there is no power from the supercharger. I’ve checked fuses and relays battery power and alternator current. Has a SAM module gone bad or is it the dash cluster that needs to be repaired?

What makes this problem better or worse?

It’s like the car is dying as things just stop working

How long has your 2006 Mercedes-Benz S55 AMG had this problem?
