Jim,

I'm not a big fan of full Auto. Now, I do like climate control. In fact, I wouldn't buy a car without one. However, only for the single zone temp settings. And that's what I appreciate in my STi - we don't fight over settings. It hasn't changed the recirc on me yet and hasn't tuned the AC on. Of course, having dedicated buttons for either of those is refreshing.

I like having air directed to feet and hands. And at a certain speed (2/5). That's my own preference and it makes me feel comfortable. I played with full Auto settings a few times since I got my first Lexus, but it never really took.

It might be related to my personality. I do like DSLR cameras and manual cars after all.

P.S.
Lexus does make a great climate control system. I always appreciated the fact that it doesn't burn its passengers with hot air or heated seats. It is blended just perfectly.

This is a good reminder for me to use AC at least once a week even in winter to lubricate those moving parts. Today would be a good day to do it as it's only +1 C.

LOL, even in full Auto it's not likely to cut on unless you need the defroster. Then it will by default to remove the humidity (frost).

I usually "manually" turn it on rather than using the auto function.

I can't figure out why water would have dripped after running the heater. I had not used the windshield wiper spray. The car has been inside a garage the whole night - so it was not outside condensation. Is the A/C running even though I have specified a hotter temperature than outside atmosphere? I mean for some reason, is the inlet air being cooled first and then heated? In which case, I better get it fixed while still in warranty period.

I have a 2013 RX350.
When you have auto selected on your heating and cooling the ac may cycle on and off to keep humidity under control even in the winter. If you have selected defrost only the ac compressor will run all the while you have selected defrost. There can actually be quite a bit of humidity in the air even in colder months.
