I have an '01 TL. Under good weather conditions, I usually set the
ventilation system to auto, but I turn off the AC. But with the AC
turned off like that, it is near impossible to clear the fog from the
windows when it's rainy and damp. I discovered today that the best
thing to do in those conditions is simply to set the system to full
auto. This way, the AC takes care of the moisture. There is no need to
run the full-blown defrost option.
But the AC seems to run a bit harder at first, and then tapers off as
the humidity clears away. Am I imagining things, or does the automatic
climate control have a humidity sensor built into it?
