Air condition

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 HVAC system 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 to get 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 still 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 again, 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 and 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.
 
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 blow warm, yet air conditioned, air.

I'm amazed at this reply. Are you the technician that checked my SUV at the dealership? I'm telling you that in every House, Car, SUV, Truck, EV, Bus and Airplane I have ever used, if I set the Target temperature to a number, regardless of the ambient (Outside) temperature, once the target number is reached the mixing valves are "supposed" to regulate the temperature of the air that comes out of your vents. it should not mater that the outside temperature is negative fifty (-50) degrees. if I set the Temperature target to be 70 the air coming out of the vents should not be higher than 70 once the temperature inside the vehicle (or House) has reached that number. That is why it is called a thermostat. it is to regulate the temperature of the ventilation system.
And to answer the part of the air being at my target setting, it is blowing air at 103 degrees after the inside of the SUV is already 94 degrees regardless of how long the SUV is running.
 
I have been experimenting with my AC a bit and the auto button is a life saver. I did have auto in my previous Audi and Acura but never bothered using it since it was a more traditional HVAC system. Now with my LC250, I set it at my desire temperature (68) than press auto. It does it's thing and within minutes the cabin is at my desired temperature.

I have posted on another AC thread about this but just sharing my experience here too. I called toyota brand engagement and submitted a claim. 1-800-331-4331. If they get enough complaints they will look at it.

I also took my LC to the dealer yesterday. I expected it to just a formal step in my complaint process BUT the service tech 100% agrees with me that this is not right at all. When i dropped the car off I brought a thermometer and had the service tech sit in passenger. AC controls set all to manual, no auto anything. Any temperature above "low" blasted about 130 degrees and low blasted like 55-50 degrees. they ended up keeping it over night and called me today to say they want to keep it the weekend. they said they compared it to LC's on the lot and they weren't seeing the same issue. they "took the car apart and put it back together" and still couldn't find any issues. They are waiting to hear back from Toyota corporate and I will make sure to keep yall updated.

seems we are all noticing this more in with the cold weather across the US. perhaps a sensor issue. Those of you saying that it self regulates the temps coming out of the vent, I understand what you're saying... on the AUTO setting. But manual should always blow out around the set temp. Toyota of Irving here in DFW agrees with me and is doing the proper investigation going up to corporate engineers.

Side note, I took the dealer provided shuttle back from dropping off my LC. It was a grand highlander hybrid, similar power train to the LC and the driver adjusted the temps manually from 72 to 70. It was not scorching hot. It felt like it was blowing 72-70 exactly how it should be.

Not related to your comment, but how do you like Toyota of Irving service dept?

This is my first time using them lol so I will report back when I see what they do here. BUT I went to Freeman Toyota (formerly cowboy Toyota) for my 5000 mile maintenance and I didn't get good vibes from them. I had a few loose trim pieces and a stripped screw I wanted them to fix. they charged me like $450 for just that. I think this AC issue would've been received differently there too. I got good vibes from the tech at Irving like they want to get to the bottom of the AC thing as much as I do. freeman just seemed like churn and burn sales tactics at the service center.

Or sorry it’s norm reeves Toyota not freeman.
 
My update posted to the other AC thread.

OK everyone, my official update since my LC spent a week at the dealer for this issue:
Problem: AC is very hot on anything besides low

After the dealer techs took my LC apart and couldn't figure it out, they called in a master tech from Toyota corporate. He worked on it yesterday and my car was ready today. That's all they can tell me until they get the master techs notes some point in the next week or 2. I will share those once I get them. Apparently he just shows up, does his job and leaves without talking to anyone.

I am suspicious that since the temps here in DFW have risen from around 35-40 to 50-55, that it is some sort of ECU/sensor issue that wasn't resolved. That maybe the master tech just didn't notice any issue and didn't fix anything. Again, I will know more on this once I get the notes. But I feel like we have all been noticing the AC issues more with the cold front that has been sweeping across the country so perhaps it fixed it self with a little higher temps...

performance after repairs: I feel sort of like he just moved the needle at which the heater kicks on BUT my AC is definitely now way more responsive. 60-65 is pretty cool but not ice cold. 65 feels pretty ambient to me. I start to feel some heat at about 67. While 70+ is definitely hotter than whatever temp you set it at, it is not MAX heat like 60+ was before. In other words, if you set it to 75 its probably a good bit hotter than 75 coming out BUT it gets hotter the more you turn it up beyond that meaning its not cranking out max heat at all at 75+ until you actually get up to the max heat of 90 or whatever it is.

Until I know what the master tech worked on and have his notes, I am not going to make anymore complaints with the dealer. it is much better than it was before although not perfect.
 
My update since I took my LC to the dealer for this issue:
Problem: Ventilation system very hot on anything besides low.

The Toyota service determined that the problem would have to be checked by a Toyota master tech since they could not identify a reason for the problem with the extremely hot ventilation system.
They set up the appointment with the Master Tech and the day came. I dropped the vehicle at the service department and the guy went to work.
Today I received a phone call and the bad news is that "They do not have a fix for the problem". Toyota is aware that a large percentage of the 2024 and 2025 Land Cruisers have this problem and they do not have a solution for this at this time.
I'll say that all the 2024 and 2025 Land Cruisers sold in the US have this problem but the owners are not aware or refuse to believe their lying eyes and keep pressing buttons and trying to adjust stuff everyday.
