Is my blower fan facing the right way ? ( W115 )

[skalie]

original now redundant question .... From what I can gather from the internet, my blower fan should be fed by one of three live plus wires ( green + random colour ) and a ground wire ( brown ).

Which would make my fan blow air out of the cabin as opposed to in to.

Thus, a quick check, did the last person who replaced the fan put it in the right way ? ( photo )

Edit: nevermind, found a post from here I read a long time ago, those three green wires are the grounds, the brown sends the plus.

The different speeds are controlled by varying the GROUND connections.

End of the day, post something on an internet forum if you need to discover the solution yourself, rather embarrassingly, almost immediately afterwards. Long story short, fan is facing the correct way.
