I had that same problem a few months ago and I checked everything and changed the control unit and it still didn't work. As a last resort I went down to a BMW shop in Fort Lauderdale and had it diagnosed, (for 20 bux) and guess what, it was the darn evaporator temperature sensor that was bad. The bad part is that it is a dealer item and cost about $50, the good part is that it is relatively easy to change. It is accessed from the driver's side and it is a probe with a black plug that is in the heater/ac box directly in front of the console.
After I bought it at the dealer I did find it on-line for about $28, but AI can't remember where I saw it. You may want to search for it.
Good luck
