The BMW "automatic climate control" is not truely automatic. If you want heat, make sure the AUTO button is pushed and the digital readout says "automatic". Then dial in the temp that you want. IF you want the a/c on you must push the "snowflake" button on the right side of the display. Another trick: if you want cooler outside air in the upper registers, look inbetween the vents and see the wheel in the middle. Turn the wheel until you see blue dots in the center area. The number of dots indicates how much cool air will be vented to the upper area.
