Hello everybody. I'm a newby, both to this forum and BMW. I recently bought a one owner '99 740I with only 60,000 miles. Couldn't be more pleased. A problem has occurred, however. The air conditioner blows cold, but only on the driver's side. On the passenger side there is no air flow at all. It doesn't blow cold, it doesn't blow hot - it doesn't blow at all. Happened suddenly with no warning. Seems to me like a fuse or relay controlling a flapper valve. Any suggestions on what to do?
