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.
