rob, if I'm not mistaken the car actually adjusts the temperature of the air depending on the temperatures inside the cabin, not outside the car. The inside temps are what determine if the unit heats/cools the air, but it won't actually "cool" the air unless the a/c is on (i.e. dehumidify and cool). If you want cooler air than that which is in the car, you can set the recirculate to "Fresh" and use the manual air direction buttons on the left side of the LCD to direct it. Once you're out of auto mode, IIRC, the car will not attempt to heat/cool the air. This could be total BS but it's worth a shot.
