Air condition

I had this exact same issue on one of my past cars, an Infiniti Q50. After digging into it, it was a simple mechanical failure of the ac blend door actuator. Meaning, it wouldn't mix the cold and warm air together to get the right temp, it would only blast hit air for anything above 60F. Check out the video below, and talk to the techs to have them see if this is a possibility

 
Maybe the CAR CARE NUT will figure this out for us, since Toyota can’t, or won’t.

This is electric in the LC not mechanical I believe. The actuator/compressor is driven by electric motor rather than serpentine belt from the engine. I think it is the exact same in the GX 550 even though its not a hybrid which is why I also see them complaining about it too. Other toyota cars like the highlander have a mechanical AC system, compressor, actuator etc which is why they are not complaining about this issue i suspect. It could be the blend door actuator is broken across all of our LC's but maybe the signals its getting are incorrect because of some complication with the all electric system
 
No offense to anyone but........... Blend door actuators have nothing to do with the compressor or heater core side of things.

LC's Air conditioning compressor is driven by an electric motor power by the Hybrid battery.
LC's Heater core is powered by recirculated hot water from the engine.
LC's Blend door actuators are electrically driven motors/servos that are used to open up or block off air passages behind the dash, thus mixing the hot/cold air flows for the desired temperature.

Bingo! Winner winner chicken dinner

It was the same way in my Q50, an electronic motor controlled the actuator. If you take a look at the video, the part that is actually replaced is a small square plastic piece (part of the actuator that physically moved the mixing door). It's behind the dash, literally took about 15 min to replace...

well if it is bad, we cant replace a bad part with another bad part. they need to fix whatever is wrong with it. I feel like it shows more in the cold weather though and IDK why that is.

Well.. something ain’t right. Maybe TCCN can figure it out. Especially since his wife has a new Tundra. Aren’t those affected by this same dilemma?

The dealership told me the 1958's have a little bit different of an ac system. no ventilated seats, cool box etc. so maybe why some folks aren't seeing the issue. but I would think if FE/premium actuators are bad, it would apply to all. also think it depends on outside temps for some reason.

Update.
After carefully reading the technical stuff on the report I received, the Toyota master Tech. took his time to compare the SUV to other SUVs at the dealership (this included New and used, belonging to other customers that are not complaining about the ventilation) he found them to be all affected. across models. 1958, Land Cruisers and 1st Edition. 2024 and 2025 model years (the 1st edition only 2024) and to his credit, he was somewhat specific. some vehicles are up to 14 degrees F out of calibration and the closest to actual temperature that he found was up to 6 degrees out. (most were more than 12 degrees off). it is his professional opinion that this problem will require a Technical Service Bulletin (TSB) and could probably be solved over the air with a software update.
We will have to wait and see.

Since you are in new york, I understand how they are all showing that because the weather is still cold. I believe that is at the heart of this issue, something with sensors/ecu when the weather gets cold. I can say it is now about 75/80 in DFW and the AC is back to operating much more normally. get as many complaints as you can in before it warms up lol so toyota knows its real.

The only over the air updates that come down are for the head unit. Anything for the ECUs has to be done by the stealership.

I can only repeat what they said.
In a related note, my 2022 Land Rover Defender 110 (p400) gets updates over the air that are ECU related so maybe Toyota is doing the same. (I doubt it but you never know)

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

I have not seen it. Where is it in settings? Couldn’t find it in the manual
 
It just got cold again in north Texas and my AC is back to blowing hot air on anything except low. This is so frustrating its making me want to trade in my LC and never get another toyota again which would suck because I really like this car. :mad:

I live in DFW too and here is a trick I have been using. Set the desire temp than hit auto. That's it. Now if your getting hot or cold, just change the temp but not the fan speed. The auto feature will do its thing and set the cabin to desire temperature.

I know it's different that traditional way of doing things but once your used to it, it becomes natural.

I just want air to blow in my face that isn't 40 or 120 degrees. Auto doesn't do that. It will direct air to the footwell vents when cold out and blow softly but still very hot. By the way, I went car camping in broken bow this past weekend. Had my Bluetooth thermostat record temps in the car while I slept. I set auto (100% everything auto) to 60 degrees. Between those red lines is when that setting was on. It kept the inside of the car almost exactly at 70 degrees the entire night. so no I don't think even auto sets the right temp. Thermometer was sitting in the trunk cupholder the whole night.

So, you left the truck on, and the engine just cycled on and off all night?
