Most likely problem is the blower motor controller and it should be found in the blower motor housing. Some of the blower motors and housings need to be replace when the controller is replaced. This is due to an update in design.
Ok so i replaced the A/C blower motor RESISTOR, its a grey aluminum looking peice of metal with like a hundred cooling spikes on it. i got it from ebay for $150, i would imagine mercedes dealership would sell for about 3-5 times that price.
