I own a 2000 318i with automatic climate control. The AC and heater used to run like a charm, but yesterday, without any warning, the ventilation fan just stopped working.
I tried pressing the AC button to see if that would jog things up a bit, but apart from the same dull 'AC-is-now-on' noise, nothing happened. Moving the temperature setting up or down or making it auto from manual and vice versa still doesnt get the fan to come back on.
Before I take it in for being checked out, I'd like to know from you experts what could be the likely cause of this vexing problem. Has anyone had this problem before? The fuses are all OK - I checked them mysef.
