Fuse location blower motor

My hvac unit just stopped working. The blower motor doesn’t spin at any fan speed. It happen all the sudden. Before I order a replacement unit can you confirm which fuse is the right ione? I checked fuse 22 of the front fuse box and 75 of the rear cargo fuse box and


they are ok

You can check for power and ground at the blower connector, and determine if the problem is upstream or downstream

2009 initial build W212 E350 AMG PACK
For me on my RHD E350 it’s the back right fuse, possibly number 1 on the diagram, 20-25amp fuse from memory

Who gave you those fuses number ?
It is so very wrong. Fuse #22 at front SAM is among the fuses for engine computer in almost all gasoline engine models of W212 and surely not HVAC blower, but is also used as radiator fan control , not main power.

Fuse #75 at rear SAM is not for HVAC blower too.


==================================


Here is the actual high power fuse location for HVAC blower. A32.
It is at F32 Front Pre-Fuse box




.






You are in luck, me is cleaning my F32 today...LOL.
Connector i3 is below :



.
The PIN 1 or the P1 is the HVAC blower fuse for USA or LHD cars


.



.



This F32 is the one on my car/ Facelift model.


===========


MB does not sell the fuse block stand alone, but you can modify it somehow.

Here is a video of F32 tear-down, opening up the F32 is rather tricky so I heard.... the 6 clips can break





.



.


Good luck.........

If only AC Computer fuse, that is fuse no 12 at Front SAM
