I just purchased my Mz-3 on Sunday. The very next day I noticed the AC does not blow cold constantly. I live in So. Fla hence use AC constantly. It will blow cold, then not so cold for a while, then cold again. I immediately notified dealer on Monday trying to rescind the deal. No luck. Service will take care of this I'm told, so yesterday they had the car all day. I was told that the car checks out properly and was checked against another 3 and it works just the same. Even more cruel, my loaner yesterday was a Hyundai whose air was ice cold 100% of the time. I have read several posts from owners on Edmunds documenting this problem, but did not see any posts on this board regarding this. I really love the car and the handling, yet I am baffled by this AC thing. Has anyone else here documented this, and if so, how are you proceeding? Thanks for any input.
