Im wondering about my climaye control...i have a c coupe with the stock climate control. How come if i set the air to rec....after a while it will turn off. heres my setting fan on maybe 3...rec button on...auto off....fresh off.

 

There is a timer on the recirculation button. This is so the air in the car does not become too stale. After a certain period of time, the recirculation turns of and outside air is brought into the car.
