Climate control: Fan off heat can still be on!

i agree totally. i noticed this long ago with the air conditioning.

i also have a problem with not being able to turn off the fan unless in the climate control screen.

i can toggle defrost and heat/air from the steering wheel but cant turn it off. that sucks...

disappointed...now my car isnt perfect...*sigh*

BUT

i can live with it

 

its not an engineering flaw, i actually like it.

I can still heat and cool the car slightly with no noise and increased fuel efficiency.

And all you have to do is adjust the temp of the auto climate from the steering wheel to the desired temp, and then turn it off

 

I agree with Areometer. This is a damn nuisance. The passive air passage would not be so annoying if you could adjust the temp without having to turn on the fan. And since that can only be done from the climate screen, it is a distraction from driving.

We have lots of days when it's cold in the morning and sunny and warm in the afternoon. So on the ride home, once the engine warms up, it gets hot in the car. Then I have to go to the climate screen, turn on the fan, lower the temp, and then turn off the fan.

This is a distraction, and a stupid design flaw.

Yes. The car is not perfect. It's the best car in the universe, but it's not perfect. That's why I'm going to trade mine in. As soon as the next major model revision comes out.

 

I'm confused: my steering wheel has an A/C Auto button that switches the fan on and off. There are Temp up and down buttons there too, so I do not need to use the Climate screen.

I also don't understand what the need to adjust the temperature is at all. Put the temperature setting to what you think is comfy and just leave it there. If the cabin gets too hot or cold just turn on the auto A/C and let the climate control take over.

 

that could cause the air conditioning to come on in the winter with the method you describe... i would think you wouldnt want that even on the warmest of winter days. i sure wouldnt.

but i will say that the temp gauge is a bit of a non issue because its cold out now and the heat is welcome.

but we have long springs and falls here (short winters thank you lord!!) and there is no way to turn off the fan after its been turned on except through the climate control screen.

its simply a design oops. there are many times when i dont want any active temperature control at all. passive air flow only is just fine and i cant do it from the steering wheel. that is a mistake in my mind.

 

I think that some of the confusion here is because Toyota seems to use the term "Air Conditioning" in a generic sense whereas we usually think of it as the device in our house that gobbles energy to cool the air. They maybe should have called it "Climate Control" instead. Their engineers are pretty smart and I bet that the compressor doesn't run much (or at all) if the cabin is too hot when the outside temp is low.

If you really want to make sure the compressor doesn't run then you can leave climate control on but turn off the A/C button on the MFD. I believe that A/C means air conditioning in the classic sense. That is the one thing you need the Climate screen for. That setting doesn't stick when you turn CC on/off, unfortunately.

I hope we're not talking about different things here because I can for sure turn the fan off with the A/C Auto button on the steering wheel.

Exactly!!!!!

And there is no way at all to go back and forth between passive air flow and any kind of temperature control without multiple manipulations on the climate screen.

 

There are climate control settings the dealer can set for you, including compressor mode in A/C auto.

AIR CONDITIONER
DISPLAY(ITEM) DEFAULT CONTENTS SETTING
SET TEMP SHIFT (Set Temperature Shift)
NORMAL
To control with the shifted temperature against the display temperature.
+2C / +1C / NORMAL /–1C / –2C
AIR INLET MODE (Air Inlet Mode) AUTO
In case of turning the A/C ON when you desire to make the compartment cool down quickly, this is the function to change the mode automatically to RECIRCULATED mode.
MANUAL / AUTO
COMPRESSOR MODE (Compressor Mode)
AUTO
Function to turn the A/C ON automatically by pressing the AUTO button when the blower is ON and the A/C is OFF.
MANUAL / AUTO
COMPRS/DEF OPER (Compressor/Air inlet DEF operation)
LINK
Function to turn the A/C ON automatically linking with the FRONT DEF button when the A/C is OFF.
NORMAL / LINK
FOOT/DEF MODE (Foot/DEF auto mode)
ON
Function to turn the air flow from FOOT/DEF to ON automatically when AUTO MODE is ON.
OFF / ON
AUTO BLOW UP (Foot/DEF automatic blow up function)
ON
Function to switch the blower level automatically when the defroster is ON.
OFF / ON
FOOT AIR LEAK (Foot air leak)
ON
Function to cut off the airstream felt underfoot while the vehicle is moving
OFF / ON
AMBINT TMP SFT (Ambient Temperature Shift)
NORMAL
To control with the shifted ambient temperature against the display ambient temperature.
+3C / +2C / +1C / NORMAL / –1C / –2C / –3C

 

Ok I haven't had a chance to read the entire manual yet and the AC thing seemed sort of funky to me from the get go. I was under the assumption that Toyota was using the term AC in a more general sense, such as auto climate or the like. Is the compressor actually running when AC is on? When I turn on the defrost, the AC kicks on as sort of expected as I've heard running the compressor will pull moisture out of the air. Like most of the other posts, I find it a little annoying to have to turn on AC, change the temp setting and the turn AC back off. It will take some time to fully understand what Toyota is doing and why.

 

heating the air will pull moisture out of the air too.

 

And there is no way at all to go back and forth between passive air flow and any kind of temperature control without multiple manipulations on the climate screen.

I thought it was me as I only have 1400mi on car. I am getting so frustrated in setting fan speed and temp without having to constantly check to turn on and off auto, A/C etc. I would prefer that I can manually and easily adjust fan speed for unprocessed outside air wihout having heat and or cooling switch in.

noisebeam... if its you then you have a lot of company... i got 7000 miles on my car and cant do it either.

i do believe its what Toyota forgot to consider.

its one case where fully automated isnt the best solution.
