AC fan stopped

2016 M4 convertible, all of the sudden the AC won't turn on. No fan. No air coming out no matter what. 85 degrees here everyday now, just set appt for tomorrow morning at BMW. Surprised at this.

I've had issues where the fans and everything will blow, but the vents somehow close themselves so no air comes out. If you have the connected drive app, try activating the air circulation and see if that kicks the system into gear.

Just an update. It was an electronic part, the "final stage blower motor resistor", that controlled the fan. Had to be ordered, just replaced the electronic part, no problems.

How many miles do you have? That part used to go on the e46 for much older cars.
