I have a 2008 2WD 6cyl Mercury Mariner. My AC twice has had this same problem. Sometimes I can turn it on and it barely blow out. Today I had it all the way up on max and it wouldn't blow air out at all. When I took it off of max it would blow "puffs" of cold air. (I have the automatic dual climate controls) When I got home I turned the car off and cranked it right back up and it worked fine. This is the second time it's done this in the past few weeks. Any ideas?
