To me it sounds like your fan only run at high speed.
If the temperature rises and the fan kicks in, do the temperature continue to rise?

If the fan only run on high speed it is probably the resistor unit or the low speed relay that has broken
Do you have the wiring diagram?
 
If you turn on the AC, the fan will be on low speed if the condenser needs to be cooled.
If you can't activate the fan relays with AlfaOBD then try a free version of MultiECUscan to see if it will activate the fan relays

NB. you can PM me via AlfaOwner or via AlfaClub Denmark if you need live help.
