2012 CLubman S - AC Blower
 

Seems the AC blower has a mind of its own. While driving down the road, the AC blower seems to slow down then speed back up constantly. And I am not touching the controls. Also, there are times when the AC is blowing cold air, then it seems to go into a type of defrost, (I call it) and it blows warmer air for about 30 to 45 seconds then it starts blowing cold again. Dealer says they cant find anything wrong (of course they cant).


Any ideas?
