Climate diagnosis: needs interpretation aid

Hey, guys.

Yesterday was a sunny day and the climate should have liked to do its job. The cooling circuit did it too, one could see on the thick line on the FS, which had set up a neat ice tank. In the interior, however, only grossly warm air arrived, so today the climate code table rolled and started:

11.7 Central valve alarm pot, sporadic blocked

15.3 Back alarm pot Static air flap, sporadic open
15.4 Remeldpoti Stable air valve, sporadic short circuit
15.5 Retreading pots Static blocked damper, see (b. 15.5)
15.6 Retrieval potential Static air valve, fault

There. 11.7. I think it's a joke. Whether that is open or too does not change the situation. Probably a feather broken or something.

15.3 ff For me now sounds like: Aua, I can't move the flap, whether it hangs on the poti or on the engine I don't know exactly.

What am I gonna do? I would be very grateful to you for your advice, even as to the place where this mouth is located.

Greetings.
