I have a 2023 GX460 model. I noticed when I set the system to “auto” the climate control refuses to turn on the windshield defogger. I have to manually turn it on or windshield and side windows fog up beyond hope. When I turn the defogger manually the temp and fan speed change, so I find myself turning it manually on/off every few minutes which got annoying fast in our 1hr road-trip yesterday.
Yes you have to manually turn on defrost as it does not know if there is fog on the windshield., the system then changes the configuration to high fan speed, recirculated air (which does increase the noise inside), and AC on if the temp is not too cold. This configuration allows for the quickest defogging of the window (fast moving, dehumidified air). I leave my climate control in Auto at a set temperature (usually 20C) and let the system look after fan speed, if I need to defog I push the defog button on and as soon as the window is clear push the button off, this returns the system to the auto mode.

seriously? So this system doesn’t have a humidity sensor or something like that ? Every vehicle I’ve ever owned has correctly controlled the defogger when needed.
is this the same experience for others ?
edit:
I had an issue with my GX where many of the settings were off /set to the wrong default. things like the key fob being disabled, and confirmation beeps when doors are locked/unlocked. I had to take it to the dealership to fix the issue and sat down with the manager and the techstream and changed back everything we could see was not in default. however, there were many things we didn’t know what the default should be.
I saw there’s a techstream setting to enable defogger in “auto” mode. I wonder if that was left OFF
that exactly. The Front/Def Auto Mode option is the one I have my eye on. I wonder if that one was left off when we were setting options back to default.
I bought a 2.0.4 TS cable last night from aliexpress. I guess I’ll know a month from now.
@Acrad does this works for you? Does it engage the defogger when it needs to automatically when in Auto mode?
TBH…. I changed this so long ago I haven’t thought about it for a while. Let me check it this week.. I am pretty sure it does accomplish what you need though.
'23 GX Premium Plus. Heat and AC work great when it's hot or cold outside. In moderate temps - around 70* ambient - the air from the dash vents is way too cold when in auto mode. Is there any way to get Auto to blow the same temp from both floor and dash vents?
I'll be following this. My 2019 has always done the same thing. My sister's 2017 is the same way, so I think this is probably normal. I just divert or close the offending vents.

hey, just wondered if you had a chance to look at your TS settings for this.

I think that’s what I may have OFF. My issue is that my windows and windshield fog up if I just leave my climate control in AUTO mode. My expectation is that I don’t have to engage the defogger ON/OFF manually every few minutes. The interior gets really cold with defogger ON so I find myself switching the windshield defogger back and forth every few minutes.
