So yesterday I was driving my 2007 Mazda 3 s 2.3l and the a/c was running fine. It does sometime make a little rattle sound but nothing big. I started the car later on and went to turn on the a/c and the compressor came on, but nothing came out of the vents. The fan will not come on at all. It want come on for the heat or any thing.

I called the dealer and they said it sounded like resistors maybe one or two. Does this sound right or has any one else had this problem?
