anyone know what the little red light is for on the recirculation button for the a/c? its a little red light in the bottom right corner of the button. it only lights up on mine if you turn off the key. also anyone have issues with the recirculation button. i know when i turn mine on it sounds exactly the same as when its off. every other car i've had when you push the recirculation button you can hear a flap close and the a/c blows colder and better.
