Is this truly an AC recirculation or is it sucking air in. My push button for the AC is on the right knob; the push button for the recirc is on the center knob. If it is AC, would the AC be activated by the center knob only as opposed to having them both on?

My experience has been that either one of the knobs activate the a/c. If you want to have the a/c light on, then push it too, but the a/c will function as it is supposed to w/ the Recirc button on only.

There are times, although I don't really know when, that you might want to run the ac while getting fresh air from outside the vehicle. That is what the ac button does. The recirc button makes the same cold air from inside the vehicle run back over the evapotator to make it cooler. This is great, when it is hot outside, but sucky any other time.

Did you notice when the fan is off air still flows through the vents.
If you hit the rec button at that time it will stop the flow of air.
