I have a '05 A3 3.2L quattro and yesterday the aircon fan started spinning and wont stop - even with the ignition off. I have tried various combinations of aircon settings and even tried removing fuses but it wont stop. If I leave the car for any length of time the batt is dead and I have to jump start it. I thought of disconnecting the batt but it's impossible to get at in the V6. A local workshop ran a diagnostic on it but no errors were reported. It's def the aircon fan, not the engine temp fan! Anyone out there got any ideas what the prob might be? I'd really appreciate any help on this.
BTW when I switch the aircon to cold it still seems to be working. Thx.
