AC on with Recirc

[Linus Gump]

You are right, but that wasn't my point. When I am comfortable, I want to stay that way, not futch with stuff to stay that way. The easiest way to do that is to turn the flow of air off by switching to recirc, but in the H3 that still means I have to mess with the temp control to stay comfortable.

Noticed the same thing. During the fall, we don't need a/c but I hit recirc when I'm behind an oil burner or a smoky diesel. Gets cold fast

I noticed that w/in the first week of my purchase. Went back to the dealer. It is apparantly a GM thing as it exists on Cadilac too.

It is a nice feature for me, but I don't see the need for the A/C button if this is doing the same thing.

That said though, it acts like a Maxx A/c switch on the H3 like Ford has to give a faster fan speed when you select maxx a/c from reg a/c.

It's a GM thing.. My uncles HD2500 does it too..

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.
