1997 e300 cabin air blower fan not working
 

Hello- I tried searching for various "w210 cabin blower fan a/c" etc and did not find what I think I need. My friend is gone fishing for the summer (as his job) and his wife's car is not blowing cold air inside the cabin strongly- if at all. The a/c system was charged a bit back and that has cold air, but not it seems cold but with little to no air movement. Since they owned the car the cabin blower has been weak. They had the cabin air filter replaced which changed little. Please give me advice...

The e320 blower has a regulator that often burns out. Without this functioning, the fan motor will push out little to no air. You can not purchase the original replacement separate from the blower, but you can easily adapt the regulator from the s320 to your blower. Only the wiring needs to be slightly modified. You can purchase the regulator for around $100. I bought mine from the site below about 3 years ago - it is still working great...
