We've all seen it: The little button on your dashboard with an arrow on the inside of your car. As temperatures get into the 80s and 90s, you might want to make sure the air recirculation button is turned on.
According toworldclassautoservice.com, the button is mainly used for the summertime, helping your car get as cool as possible when it's hot out and you have the A/C on. The button helps recirculate the "kind-of-cool" air you get from your A/C when you first turn it on, and the longer it's on, the cooler your car gets until it's as cool as possible.
