Another little trick is to use the rear heater more. In winter, I wait
until I have good temperature on gage, turn on the rear heater fan, let
it drive the chill out, then turn on the front heater fan. Once moving,
I turn the blower off, or on low. If that rear heater blower is running,
it doesn't take much to keep the front warm. In really cold climes,
north of Mason/Dixon, more front blower may be necessary, but even in
Alaska, I found that on the road, with the engine putting out good heat,
the rear blower did a good job with minimal front blower help. Slow
driving in town was a different matter, and during times when there was
windshield fog inside or snow/frost outside.
