There have been numerous posts on this and other very similar problems. Try doing an archive search on "heater valve(s)". My exact same problem was fixed a couple of months ago by replacing the heater valve...an easy solution.

With the cooler weather change in Tennessee, I've begun to drive w/o A/C on. The outside temp is perfect for sunroof open and windows up. The vent settings are on cold, yet there is a stream of heated air disrupting my comfort.
fan on medium-ish
AUTO button on
temp pucks at 63 degrees f.
the vent setting between the vents above the radio is set to blue.
Is it normal to have so much heated air remaining on the side window vents and the windshield defroster? It seems entirely too much, to the point of overheating the cabin.
