Climate control not working
I have a w203 2004 c240 160,000 on it. The When i turn on the climate control nothing comes on. I tried the reset pushing the tow buttons and it does nothing. I hear no air circulating or anything. I get no blower motor noise at all . I get no codes also from checking. What could be the problem, or is it just a simple replace the Blower motor. But as stated nothing seems to come on.

I had what may have been the same problem on my 2005 about 6 weeks ago. I was driving and suddenly the blower stopped working. Blower Replacement
I have an ICarsoft code reader and it had a code for the blower regulator. I sourced a used blower from a car that was being "parted out" and that solved the problem. I may also have been able to replace only the regulator, but the entire assembly was inexpensive and there was no point in removing the regulator from the rest of the assembly. My blower had been "chirping" on some cold days last winter, and the bearings may have been wearing out.
