C126 500 SEC
Hi,


Newly registered with my new to me 500 sec.

I have an issue with the ventilation in the car.

With the blower running, the defrost vents below the windscreen are hot and all the rest of the vents are ambient. Adjusting the temp wheel has no effect on vent temperature remains ambient and defrost is hot.

Where do I need to look?


Also AC clutch does not engage and a/c system is full as has just been recharged.


thanks
