Air Conditioning problem
2000 BMW 323 4 cyl Four Wheel Drive Automatic 145100 miles
----------------------------------------------------------------
My air conditioner nor heater is working (nothing is blowing out of the vent) and the dash area is neither lit. What might this be?

The fan is controlled by what is called a final stage. It needs to be replaced. It is probably best to seek out a local BMW expert to assist you with this. The part is about 120 to 150 bucks retail and it takes about a half an hour to install
