We have had the "aircon won't blow through the dash vents" problem twice now. The first time it was water in the plenum shorting out a motor that opens the door to the vents. The second time it was the IHKA module gone bad. Both were spendy repairs. Both times the problem was intermittent - one trip the system was fine, the next defroster only. No idea about the iDrive issue.
