[RickFLM4]

I live in South Florida and find the a/c works fine. I drove Audi and Lexus since 1994 before I got this M4 in July. When I first got the car I thought the a/c sucked until I moved a thumbwheel from red to blue. I don't understand the point of / need for that thumbwheel but once I moved it to blue I just left it there and everything is fine.
