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?

Dunno if you are imagining things, but it definitely takes energy to
condense the moisture from the air. IIRC the heat transfer to condense a
given amount of water is about 5.2 times the heat transfer that would be
required to cool the water from boiling to freezing. The A/C has to work
harder just to cool the air while removing humidity.

If you look in your manual it says you should always have the climate
control on full auto and only set dial to cooler or warmer...I never take it
out of full auto and I've never had a problem

I purchased a 1999 3.2 TL a few months ago and in regards to climate
control, in the FULL AUTO setting, does it mean that the system turn the
AC on & off as needed? The manual is not specific on it.

Thanks,

Yup. That's what it means.
