S204 heater blower not working.

[gatty]

Hi some help if poss please. The heater blower on my 2012 s204 has stopped working but A/C control panel still lights up and accepts input. I have checked blower from inside engine compartment and it turns OK, not seized. Struggling to find my fuse card and cannot establish from net exact fuse responsible for blower. That was the 1st question..... Next if need to replace blower anyone know who makes original? Mercedes want £276ish for new one........ ECP want£162 after Halloween code and car parts for less £131. Both latter are Hella make.
