abajaj is an unknown quantity at this point
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.

325i heater/ac fan not working

Have a 2001 325i - the ac/heater fan was working just fine - then all of a sudden - the fan decided not to turn on? Some say - check the fuse - then others say - have to replace fan resistor final stage. Any other suggestions? Thanks.

Shit, this thread was 8 years old lol

Odds are your blower motor or resistor has gone out. On a car of that age its not uncommon.
