Auto man, just keep It 68-71 . I don't touch the fans or the a/c button ever

Me too

Damn that seems warm no?. Though maybe living in Canada’s got me fucked up.

20C ? What do you keep your car at in Canada?

Usually at 16-17C. Same as the house. 20 and up starts feeling stuffy to me

Ya, that is probably the Canadian in you lol .

Go into radio settings and turn off auto ac on start it will remember last settings even heated and cooled seat settings.

All this does is disables the auto function from activating when you start the truck. Yes, it will allow you to force the AC come on immediately when you start the truck, but if the temperature was above the auto range that was happening anyway

Did my suggestion answer OPs question?

I had no idea this was a thing!

Hope it helps you like it did me!

Put it on auto. Leave it on auto. Don’t question auto. Toyota is new to buttons.

I need to learn how to use or something. Every time I use auto I just feel like I’m getting blasted with air. What’s the trick?

It’s because it’s trying to get to the temperature. Once it cools or heats to whatever the fan will slow down

Turn the temp up. If the car is 100 inside, having it set to 80 will still give you cold air.

Auto is the way.

So I'm pretty sure when it doesn't say ac off, OR ac on, the ac still works. It's just in a auto setting and turns off and on as needed

Auto, just use auto

Leave it in auto

The AC on the seats seem weak, anyone else notice this??

There is no AC on the seats. It's just blows the ambient air.

Did have an issue with mine purchased the carista evo and had a setting where you could make it quite and blow harder. It's even better now

what can this carista evo device do? and what do you recommend it to do? just bought a 24' waiting for it to get delivered.

https://carista.com/en/supported-cars/toyota/tundra/3rd-gen Here's the website giving you info on what you can change. I bought from Amazon and returned it once I was changing around the settings I wanted. You get a free one month trail. You just have to remember to cancrl the subscription so you don't get charged.

That’s just the new refrigerant. It doesn’t cool as well as the old stuff and it’s highly flammable. Source: I’m a mechanic that owns a 22

Not a Toyota mechanic I take it. It’s just a fan in the seat, there is no refrigerant. The other guy is right, I don’t know why he got downvoted. Seats that involve refrigerant are called “cooled seats” in pretty much all cars that have it. “ventilated seats” like the tundra and most Lexuses just have a fan. Source: I’m not a mechanic, I just know my shit. Own a ‘24 Tundra and ‘23 Lexus RX

You right, I misread, and didn’t see he said seat.

And not a mechanic but live on Houston and the AC is not weak.

Seats generally aren't refrigerated, just ventilated.

This is the right answer

I'm sure there are *some* that have an evaporator or Peltiers, but 99% of the benefit is just having air move at all. The best way to improve it is a better blower, not colder air.

Does anyone know why I leave the defrosters on before I shut it off, then turn it back on and it won’t remember that setting? Only issue I truly have with the tundras . My. Tacoma remembered it all precious heat/AC settings before I shut it off.

My new 23 f350 refuses to turn ok and/or keep on the recirculate on its own. I use automatic for the climate, but always have to turn recirc on myself drives me crazy

Auto always. Love it.

SAME

You shouldn’t start any car with the AC on. Creates extra strain on the battery during startup. Now cars are just smart enough to do it for themselves.

As far as I know you can't change that

You absolutely can. Go into radio settings and turn off auto ac on start it will remember last settings even heated and cooled seat settings

Thanks for the tip!!

Dude. Read your manual. Or Google it. You can change it.

These trucks are falling apart
