Turbodiesel,
I don't think you confused me. It is just that I cannot take the sidewall off in order to get to that screw on the right that holds that "kneepiece". The floorpiece seems to overlap. I 'll try tomorrow with some turning/lifting before I unscrew.

Suginami,
take a look at my photo. It is a shot to the right from where the glovebox used to be. I don't see anything that resembles a fan motor unless it is in that black plastic hose.
Thanks
Reinhard Kreutzer
