I recently bought a 2010 c300 luxury 4matic. It was working fine and now out of the blue I have tons of issues with it.

problems are listed below:

• radiator fan kicks on high all the time
• power seats don’t work
• right SRS malfunction
• power windows do not automatically go down, will work normally but not automatic
• windshield wipers don’t work
• turn signals don’t work
• AC compressor not working
• horn doesn’t work
• telescopic steering wheel doesn’t work

not sure where to even start with fixing problems. Does this sound like a front SAM? Don’t want to start replacing parts without a direction first.
