My wife bought this off the show room floor. I was against it but who am I? lol.... Anyway, besides minor things like shakey steering etc. the cars pretty nice. But today I took it to home depot, and the a/c isnt working. Fan runs fine but compressor isnt coming on. Im a certified hvac service tech. But I would never even dream about the nightmare of servicing an auto a/c. So my first question is: Wheres the fuse panel.. for the a/c? and second, where are the gauge ports for the 08 mazda 6 a/c refrigerant valves?
