Was in the 70's this weekend in Atlanta; cool outside, I was NOT using the A/C or any fan or any HVAC control but the Car was BLOWING IN HOTTTT AIR as I drove; .....called the dealer and he said to put the button on recirculate which will close the vent and not allow air flow into the cabin; but I thought I could not used that button or the economy button UNLESS the heat or A/C mode was on or the fan; he said to turn the fan on,press the recirculate button and then turn the fan off.....I do not want to have to use the A/C with the temps in the 70's....Dogdoc
