A/C Compressor not cycling and upper vents not working 900 1997

I have a 97 960 and don't my AC compressor does not cycle. In addition, my upper vents don't have much airflow when fan is on at any setting--suggesting some of the doors in the ventilation system are closed. The recirculation button also seems to do nothing when pressed. Given these basic symptoms I was looking for some possible guidance.

So far I have checked the fuses, the ECC and the solenoid valve controller and can't find any apparent cracks/shorts on the board(s). I am thinking that the solenoid valve holds the answer as the vent doors are not responding when I move the selector switch on the dash around.

Based on these symptoms, any thoughts on possible areas to look at or look at more carefully would help a ton.

Best,

Angus
