Air condition

[LC_DFW]

I am in Dallas, drive in normal mode and when I left for work in the morning it was around 32 degrees outside. I remote start my car from the app and the AC is already pre-set to 75 degrees. When I get in the car, its feels nice and comfortable but once I start driving, its starts getting really hot inside to the point of being very uncomfortable. I put the temperature down to 70, than 65, 62, and 61 but even at 61 it blows hot air. I put it down to LO (60 degrees) and it starts blowing cold air and gets really cold. I put it up to 62 from 60 and it starts blowing hot air, making me very uncomfortable. It seems like there is no middle ground here. It's either I am setting it on 61/62 degrees and dealing with hot air blowing at me or 60 degrees with cold air blowing at me. But wait, there is a twist. When the cabin gets too hot, I turn my HVAC system completely off but there is still hot air blowing at my face.

Very frustrated with the HVAC system in this car.

This has been my experience as well.

I believe that too, but compared to other vehicles I’ve owned, Toyota vehicles, the behavior in cold weather is noticeably different, on the hot side of things.

Where I’d generally keep the heat set at 68-70F in other vehicles, that’s way too hot in the LC, and I’ve been keeping mine set at around 62-64

It’s not an issue for me, as long as the A/C also works in the summer time and keeps me cool, but I did have to go through a trial and error period with the LC’s temp calibration.

On my longer drives (3-4 hours) in bitter cold weather I've been keeping my temperature set to around 64 or 65. I do have a significant issue with the blower when it is set to use only the lower vents (near the feet). The sound is very loud and something is definitely not right. There is another thread on this issue already.

Does your car still blow hot air after you turn it off?

I remember reading in the manual that below a certain temperature the ac compressor will not turn on. So there’s nothing wrong with the HVAC, it is the way it designed. And if memory serves me, the only way to get the compressor to turn on below a certain temperature is to turn on the front defogger.

there is another similar thread on here with good recommendations from other experienced owners.
I turned the sflow off first, helped a bit, then turned the Rear to auto. I did this all in infotainment. Turning Rear to auto provided the greatest benefit. With temp set to 61 or 62 and outside temp of 27f i was comfortable for 35min commute. Hopefully this works for you. Oh, i dont wear a jacket in car anymore either!

how do you change the temperature unit into celsius? mine only has F and I can not change it. Is this because I am in the U.S not Canada?

Look in the manual, it should be in there. I have seen it a couple times just playing with the menu. Temperature units.

I just use the seat heater and heated steering wheel and turn the heat off once it is warm inside. If it starts getting chilly I turn the heat back on for a few minutes. I never wear a jacket in the car. It has been in the teens where I’m at.

These are built to move air to match the temperature you pick. They aren’t like the old ones where there’s a knob that points to blue if you turn it one way and red the other.

What I think happened with you guys is it got cold out. And the car began to interpret the same temperature goal setting you always had as requiring heat now, versus cold.

If you have the car set at 68 degrees and it’s 38 outside it’s going to blow heat. If you have it at 68 degrees and it’s 92 outside, it will blow cold.

Good luck.

In my case, the Temperature outside is 32 degrees F. the setting is at 64 (and AC on) and the temperature inside the SUV is 97 degrees F and still blowing HOT air. (try to explain that)

Yeah, same explanation. You have your temperature target set above the ambient temperature of the air, so the truck blows hot until the temperatures match.

What these can’t do is control the intensity of the effort to move the air temperature towards the target, like a BMW for instance can - so it feels like it’s blowing really hot air as it tries to move from whatever temperature it thinks the air is to your target setting.

Whether the AC is on is irrelevant. The AC button activates the AC compressor and removes humidity and heat from the air like an air conditioner does. But if you have the car set to heat, it will re-heat that air using the coolant system and the air that comes out of the vents will be hot. Nothing new about that - on any old car you can activate the AC and turn the temperature control to the “red” and it will below warm, yet air conditioned, air.
