Escape Heater Always "On"?

I'm in Hawaii and almost always use the A/C. Last week I turned the A/C off to test the mileage. I noticed that with the windows down the ambient air was significantly cooler than the fan circulated air coming from the vents, even after miles of driving.

The temperature selector works: turned clockwise it gets HOT immediately. But set completely counterclockwise, the circulated air remains warmer than outside.

Anyone else notice this?

I think the heater core is always full of hot water [not controlled by a valve] and that a "blender" flap directs air over or around the core. Is that right? I it possible that it is stuck partialy open and needs adjustment?

Thanks for any comments.

Being a reasonably cool day here in SC (only about 83), I tried out what you are saying. I had my windows open, and the flow directed to dash and floor vents. The air coming from the dash vents was definitely cooler than the air coming through the window, but the air from the floor was about the same as or maybe just a bit warmer than the air through the window. The blend flap may not be stuck on yours- it just may be that there is not that much insulation in the firewall, and the heat gets transferred through the duct work. Couldn't hurt to have it checked though (except maybe in your wallet).
