Is it normal for cold air (like air conditioning) to flow out of the vents when outside air temp is in the 60s, the air conditioning is turned off, and the air recirculation is turned on, and the climate control system is set to auto...even when the cabin air temp is warm (no cold air to recirculate)? Is the air conditioning system turned on when air recirculation is turned on...even though the air conditioning button is turned off? If not, what's wrong?

Also, I notice that air conditioning cold air fluxuates greatly when temp is set low and system is set to auto with A/C set to on...and seems to blow colder when vehicle is under load or accelorating, then warmer when not under load, coasting, or decellerating. Is this normal?

 

Welcome to the forum.

There was a software upgrade for the A/C for the 2007s. But even after I had that done, it still seems to require periodic temperature adjustments.
