Re: Alfa 166 climate conrol fan not operating
If you look behind the bulkhead, near the pollen filter, the wiring harness contains the 12 volt supply to the fan motor. On mine its a heavy wire (Grey with red stripe). If you can scrape away some of the insulation to reveal the copper wire, try taking 12 volt supply from somewhere, I used one of the heavy studs on the bulkhead, and hold it against the bared wire. If the fan motor works you have the same problem a I had. I think the connection is lost somewhere behind the dash, maybe corroded wire. I eventually cut the grey/red wire and joined the new 12 volt supply, with a 30 amp inline fuse. Its worked perfectly ever since.
