    When I have that silly front defroster grid button pressed, the
climate control *not* in auto, and the A/C button isn't lit, is the A/C
still running when it's in defrost mode? Why can't they just have
defrost as another mode in the mode menu...?

Because people such as yourself don't understand that "defrost" means
"dehumidify" and that only the AC can dehumidify.

Toyota lawyers, ever the nannies of the world, want to prevent lawsuits
that result from stupid people driving around with their windows fogged
up and then claiming they caused some horrible accident because the car
didn't read their minds and do what was needed instead of what they told
it to do.

So they program the car to do what's needed--and, to prevent phone
calls, they specifically tell it not to light the AC light.

At least they don't do as recent Hondas do and carry over the A/C
function to any subsequently selected environmental setting, even in
dead of winter.

     Wrong again, troll-breath! Heat will also dehumidify, as will
slightly drier air at the exact same temp as the inside air. I want to
make sure I can keep the windshield clear without either freezing my
feet with the Floor/Defrost setting, or being unable to briefly switch
to Recirculate when a diesel truck gets in front of me when I'm in that
stupid 'Front Defrost' mode. Toyota has made this an impossible dream.
On every previous car I've owned since 1986, including our Camry, one
could set the airflow to "Defrost" and still be able to activate -
briefly, to prevent re-fogging - the recirculate setting.


    So instead, they're going to cause accidents by making people look
down and repeatedly punch buttons until they can shut off the outside
air intake in heavy traffic. *Great* strategy.


    I hope that you are, once again, wrong.

    Any Toyota techs here who can give me a polite, informative answer?
