Is there a quick way to turn on or off the A/C aside from the front defroster button? Strange there is no hard button there. Its takes forever to go thru the NAV system.

You should have an Off button next to Auto

Yep, that OFF button will do it.

You can press OFF, but let outside air come in, and that will still provide air flow into the cabin without AC.

sirtiger

thank but that will turn off all the air...I just want the A/C off. This is one strange thing missing on both 3RX and 4RX

There are shortcut icons to the far right of the screen. The air icon is the bottom one.



Once you click on the air icon, it will bring up the air option screen. From there, you can turn off the a/c.

sirtiger

thank you. I am aware of that but it takes quite a few steps to get there. Its strange why Lexus brain team didn't put a hard button on the consol.

dchar

Probably because most people don't turn off the AC.

sirtiger

most other cars I'd own has a button. The most common reason why an AC goes on is when I turn on the defogger. At some point, I don't need it anymore and it gets a bit cold inside

I alluded to this under another post, but decided it needs it's own discussion. Sometimes I like the cold air from the A/C compressor and sometimes I want to keep the temperature low but not have the compressor (no A/C). In 40 years of driving, all my cars had an easy AC ON switch with a green light indicating the compressor would come on as needed. This RX does not seem to have that. And frankly I don't remember if my wife's 2015 RX has it (she's at work or I'd look).

What's the deal with this for both cars?

it's accessible through the navi screen under climate section

RXOwner

Your AC compressor only comes on when needed when you have the AUTO set to on and the temp inside the car is higher than the temp you have set.

On my 4RX when I push the OFF button next to the AUTO button, it locks out the AC compressor and yet still allows fresh air and heated air to move through the system. The 4RX will do the best it can to cool and heat without the AC compressor. If you want to enable the compressor again you just hit the AUTO button next the the OFF button.

Seems simple to me, like past Lexus I have owned.

I just leave mine in auto all of the time, so it isn't an issue for me, but it's frequently discussed here both in the RX and other model forums.

My '13 RX does not have a dedicated physical AC button, but my '14 IS did (though I never used it). My current '15 GS does not have one either.

Doesn't hitting OFF turn off the fan too? I don't want to stop the air flow, just no cold compressed air. And doesn't hitting AUTO crank up the fan? I want the fan to be where it was before...I don't want to have to hit the fan down buttons again to crank the fan back down.

Jeez, why not just have an AC ON/AC OFF switch like has been in cars for at least the 40 years I've been driving?

RXOwner

When I push the OFF button next to my AUTO button the other climate control buttons are still lit and air still comes out of my dash so I think it just disables the AC compressor. I hit this OFF button all the time when rolling down the windows in the early part of the day.

I suspect Lexus wants us to leave it in auto.
