There are a number of reasons why a blower doesn't work. Could be a failed control panel, a burnt fuse, a failed blower motor, a failed relay or a bad connection somewhere. There's probably an electronic control module in the system, too.
First thing to do is check to see if there's power and ground at the blower motor connector. If you have power and ground and the motor doesn't spin, the motor's failed. If there's no power or ground, you need to look deeper.
You may need a Benz specialist or an auto electric shop. Here's a directory link for you:

Thanks, turned out it was the resiestor switch(knob itself) and it was a $290 dollar part. I think mercedes parts are a rip off. Doesnt want to make me buy another one in the future.
