It is possible that the evaporator temperature sensor is bad. It is a fairly common problem with these vehicles, but without proper diagnostic it is impossible to be sure. I recommend having a Mercedes-Benz dealership diagnose and repair the problem for you because of the complexity of the system. Here is a link to help you find a shop:
