Do you have electronic 4x4? If so it runs off of air pressure and if you broke that line your ac will do that. Mine did it about 6 months ago and that was the problem. Everytime i put it in 4wd it would kick the a/c from the regular vents to the defroster. As soon as i would put it back into 2wd it switched back. I found the break in the line and it went away. Hope this helps...

The broken line on mine was in the front inner fender well. It runs right along with the brake line.
