Airconditioning not blowing cold

[AlexDenis]

Hi everyone, i've got a 2008 Polo 1.2 (BZG) of which the aircon is not working. I've had it regassed (no leaks found) and i've replaced the pressure switch as well but that didn't do it. I have noticed that the radiator fan is not spinning when the AC is turned on, it only seems to spin when the coolant temp reaches 105C to cool it down. What could this be?
Do these cars use a clutch or variable displacement compressor?
Greetings, Alex
