Climate control: how to access that stepper?
I can’t seem to find any diagram that shows where is/how to access this specifix stepper motor?
I suspect it is the source/cause for my “passenger side is hot” issue (cold air not blown even when it’s cold outside).
Third image shows its size compared to the other (4) steppers.
(And yes, I got the one in the picture as part of a “used” package of steppers from a working-known truck, but seller/breaker does not have any detail)

Anyone?
Or did I miss an obvious diagram in the workshop manual?

I think I got it from this picture. Not 100% sure what the setup is in a left-hand-drive Disco 3, but it seems attached to the interior side of the blower fan intake. Likely to outside vs recirculating blend door.

I'm pretty sure that larger motor is for air recirculation. The four small stepper motors for the two blend flaps and the two that control screen/face/ feet are mounted on the heater box.
I'm sure I have some diagrams possibly on my old laptop, I will have a look later for you.
I replaced my stepper motors about 10 years ago now so my memory is a bit dim!Stu

Quick update here: thanks! Those pictures helped! Same setup on LHd, but mirrored.
