Heat coming out vents when heat is off
I have a 1992 318is and I can have the heat off (temperature knobs turned all the way to the coolest setting), and I still get very hot air coming out of the vents. I should point out that I no longer have the belt on the compressor, since it needed freon that is no longer available. So I just took the belt off. It was fine up until this summer....I now always have hot air coming out of the vents.

Sounds like something is wrong with the heater control valve. it could be stuck open. Sometimes, you can disassemble the valve and clean the insides of it, making it work again.
