How to disable V90 air conditioning in winter?

[martin calva]

My Question:
What fuse (or relay) can I pull out that will disable the air conditioning, yet leave the rest of the heating and ventilation system in operation?

Background:
Evidently, with the V90, if you direct the air to the windscreen, irrespective of the temperature your have set the control to, the air conditioning comes into operation and the little blue light behind the air conditioning button lights up. So far as I can see, there is no combination of controls that allow you to blow hot air on the windscreen without having the air conditioning coming into operation.

In winter I have no need for air conditioning but I'd like to be able to blow hot air onto the widscreen - for example when someone with a wet coat has got into the car - without the A/C operating.

(I have looked at the page in the V90 electric manual but I cannot make any sense of the diagrams.)
