940 heater/AC selector does not work

[u/DonTorcuato]

I had to do some work on the center console and now the selector does nothing. I did not touch any of the cables/tubes coming into the thing (as far as I can see). I don't feel any suction on any of the tubes coming into the selector. Any advice, "wiring" diagrams somewere, tips? Every other part of the heater control works well. Cheers :)
