A few days ago, my car stopped blowing heat out of the vents. I checked for the coolant level, it's good. I also checked my fuses as well too, they are good. I've also replaced the thermostat and bled the system. Still no heat coming out on the vents. Can you help me? Thanks!!!

Control units fail on the BMWs quite often but you still need to check the control valve to make it's working.

your car uses an electric heater control valve to allow hot water to flow from the radiator/engine into the heater core. this valve is controlled by the climate control unit on your dash. you may need a good BMW tech to check this for you.
