Got problems changing the airflow direction on the interior fan, it´s stuck on "winshield/feet" can´t make it change...
The display changes but the airflow direction don´t
I can change the fan speed up an down too.
Seems something jammed, but what?
Maybe it helps spray some lubricate, but where???
Really hope there´s no electrical problems.

Probably a bad mode door actuator. Pull the DTC's.

I aint got any troublecodes right now....
Any good tips how to reach the "mode door actuator" i guess it´s not easy.

LHD Part #46 is the mode door actuator

RHD part #49

Ok, by the pics it should be located above the air cabin filter.
is it possible to reach it without replacing interior parts or anything else??

Not sure as I have never had to replace one ................ yet.
