Question - If the AC in the car is making you too cold and you turn
the temp dial to "warmer" to make the air coming out less cold will
that make the AC work harder and make your gas mileage worse? Why?

You already know the answer but just an FYI, driving with windows open
will produce a bigger drag and decrease mileage than using the AC.


I've had my windows closed since 1967!!! Can't stand wind noise.


Same here. Love climate control, just never think about it any more.
Maybe once or twice a year I'll open the windows for a short ride.

I don't understand climate control.

If i get in the car and it's cold, am I supposed to leave the temp set
to, say, 70, and the heater will put out very hot air until it gets
(close to???) 70 and the temperature of the air will (slowly???)
decrease and be only warm when the sensor says 70?

It seems to me the air is never that hot unless I turn the temp up to
80, and that if I leave it on 70, it will take forever to warm up, but
I'll admit I haven't kept tabs that closely.

Do. It should reach 70 in the same time regardless of what temperature
(70 or above) you have it set for. There MAY be a small difference,
but on my Ford I have never noticed it. My wife likes to fiddle with
the settings because she THINKS it will warm up faster, and BELIEVES
it does, so she FEELS it does. What really happens is it just gets
warmer, so SHE warms up faster.

I also don't like the Toyota climate control because it keeps changing
whether i get outside air or not. You would think whatever setting it
had when I turned the car off would be the setting when I turn it back
on, but No. (I think it depends on the outside and inside temps,
but knowing for sure would mean detailed records. )
You get outside air ALL the time with a Toyota climate control system
UNLESS you set it to MAX AC. The system will never restart in MAX AC
mode by itself, nor should it. The system is most efficient in the
normal mode.


Why would an AC system that draws in mostly outside air at 90F be more
efficient than a system that mostly recirculate inside air at 75F?



Outside air is NORMAL AC. It is also NORMAL HEAT. Without outside air,
particularly without the AC working, the humidity builds VERY quickly,
the air gets stale, and the car starts to smell like a dead man's
arm-pit. Not to mention the carpets stay wet, the windows fog up, and
the car, generally, becomes unpleasant.

Nonsense. The AC removes moisture from the air, just like any AC
system, and there is almost always less moisture in the air that's
inside the car than outside. I've never had a car that stays wet,
windows fogged up, stinks, with the AC set to fresh air or to recirculate.
