Is there any way this can be adjusted (by the dealer, or anyone?)

Even at the highest setting, the air coming out of the vents is not very
hot - "pretty warm" at best. It seems much cooler than I've seen in other
cars.

Recently it was around 5-10 degrees F here, and when using outside air, the
heater air was barely hot at all. The only way to even make the car
comfortably warm was to use "recirculate" to reheat the cabin air, but this
fogs up the windows. The solution there I suppose is to use the A/C also
but this wastes gas, especially in the winter!

Any ideas? I know the engine runs around 195F, so there's got to be a way
to heat up that air a little more before it comes out the vents.
