Hi MrAL300,

When you state you're using fan only, do you mean you're selecting vent, or are you also possibly using the defogger? The air conditioning may also come on automatically when you select defrost (p. 8-2 of the owner's manual). If you are simply selecting vent, the A/C shouldn't necessarily come on automatically. Are you able to turn it off at all, or does it stay on regardless of whether you push the button to turn it off?
