What happens when you short the connections on the plug that fits the switch?.
Do both fans work when the aircon is on or only one?.
The fans only run at a slow speed when the aircon is on,and then kick in at a higher speed to cool the engine.Check the fuses and relays as the two speeds are controlled seperately.
If possible,check to see if you have a 12 volt feed to either fan when the switch plug connections are shorted.If you have,then the fan is faulty.
I'd rather push my Alfa than drive a BMW....
