No low speed Fans, no AC

[RIAL]

S3 8L
Is it possible that my AC compressor clutch is not kicked in because of a bad rad thermo switch? Have no low speed fans but they R fine because I test them bridging the rad switch connector. Gas and pressures R fine too.
FCM and Climate Control replaced before and I'm guessing the low speed Fan must be a requirement for the AC to work and if the switch is not turning the low speed, them no AC compressor. Does this makes sense?

Can someone tell me if this makes sense because it doesn't make must sense for me.

So, my AC is not working for a long time and everything was pretty much checked until I found on one of the engine measuring blocks, Compressor OFF: Shut-Off requested by Engine Control.

Today o took the to Audi dealer for a AC diagnose.
Just received a phone call saying that the engine hose breather and crankcase hose breather need to be replaced.
WTF???!??! Is this reason for AC compressor Off???

Also can some one show me this hoses?
Tks
