My daughter has a 330i, her AC or vent fan quit working, the display shows it working when pushing the button but no air flow. Could this be as simple as a fuse change?
I've had a similar problem with my BMW as well, I had to remove the fuse to keep the blower resistor from running nonstop until it would run the battery dead overnight. Now I cant get any air/heat from any vents, replaced the fuses, now what?

Re: 2001 BMW 330i..Fan for AC/vent not working?
It's either a fuse or it's a bad blower motor, it could be a bad blower
motor resistor but usually you'll get either high or low only, so if
you have nothing on any speed, high low etc, and all the fuses are ok
chances are it's your blower motor.

its not a fuse i had the same problem on my 03 x5 it an ac resistor thats at fault it controls your fan once it goes your fan wont come on or comes on intermitently once again the faulty part is a blower motor resistor should be 100 bucs at dealer or if you shop around i got mine for 75 from local parts store (carquest)
sounds like the resister for the fan is failing. it is located under the dash on the duct work for the blower (fan). you will see two wires going to it. unscrew the bolts or screws that hold it in and replace it with a new one. it should work fine after that.
