are you saying that the A/C turns on by itself in certain modes ?
my A/C light will only go on when I press the button

Yes. Whenever you are in one of the 3 defrost modes (full or split). The light doen't come on. All modern cars that I know of do this. It makes the A/C last longer to run the A/C compressor once in a while during the winter. I will put the A/C on manually to accomplish this, but only when I am going down a long hill using DCFO.
