I've received a couple emails regarding failure modes for the climate control head. It seems that it can also fail in such a way that when the climate control system is turned off (by turning the fan all the way down), the fan will continue to run. Other failure modes include: selected buttons will have no effect, or the temperature will reset to 70 degrees. Bottom line, if anything like this happens, I would suggest that you replace the climate control head. As for replacing it yourself, unless you have access to a BMW diagnostic computer (not the $50 "diagnostic tool" used to reset the service lights, I can assure you) you can't program the unit properly. Take it to a dealer.
