climate control temperature adjustment

Hey all,

when adjusting temperatures for your tundras, is there a faster way to get from LO to HI instead of hitting the paddle 20 times or holding it for 30 seconds? my commute in the morning usually involves me using the heater, and when i'm heading back home for the day, the weather outside has warmed up a bit so i'm having to use to AC. please tell me there's a faster way to adjust temperatures. thanks in advance!

side note: i do not have the dual zone climate and i've got the 8'' screen, if that matters. also, sr5 trd-offroad. thanks!

 

Not that Ive found in 3 Toyota models now with the same dual zone controller

 

sorry could you repeat? i don't understand what you're saying.

 

Your avatar has the look of what Yotas daughter looked like after the recall!

 

That is one of my pet peeves. There should be a button to jump to Lo. Which is where you need to be after getting in a hot truck, if only for the increased fan airflow there. I am not sure why they designed it that way. On all of my other vehicles Lo just makes the compressor stay on, but full airflow is available whilst still anywhere in the numerical temp range.

 

i was spoiled with my 3rd gen tacoma that had knobs for both temp and airflow control. spinning it CW or CCW completely would get it to where i wanted it. now with these damn paddles, sitting there just tapping away until you get to HI or LO is so daunting.

 

It's so interesting to see what gets some people's panties in a bunch.

MY wife and I just spent a month on vacation in SW Florida. The temps were abnormally high, with the heat index over 100 on several days. We just left the temperature control on 70 in auto mode. Both of us were impressed by how well the climate control system worked. No complaints whatsoever.

I should mention, I did do the Carista climate control adjustment, which really helped.

 

this argues nothing. you're stating your situation where you used your climate control at a certain constant temperature while i'm asking about going from maximum to minimum and vice versa. if i lived in an area where it was constantly hot, then okay, sure, i had it at cold, and i'll continue using it at cold. as i stated in my original post, i'm asking about MY situation where i'm having to go from max hot to min cold on a daily basis. see the difference?

 

All I can add is if you have AUTO this makes all the difference as it will use max cold to get down to the set temp say for example (70) and if it colder out it will try to heat the interior then level out the output. Remember too the engine needs to hit a certain temp before the heater will even start to work.
If you don't have AUTO then just set the temp before you exit the truck for the next morning. I live in PA 40 degrees Friday night to 75+ Saturday afternoon.

 

I have a similar situation in spring and fall. I use Auto 72 in the morning and Auto 70 in the afternoons. Two taps of a physical button.

 

ill give it a shot and see if it's what works for me. thanks!

 

The issue is that you get significantly better (increased) airflow in LO. If it is 100 degrees inside the truck and you have it set to 68 the truck will not cool off near as fast as in LO. So, on a really hot day I have to tap, tap, tap, tap, tap when I get in. I know, it is a first world problem, but a PITA nonetheless.

 

You can also try the Carista climate control adjustment Matt2015Tundra mentioned. Modern cars' HVAC has tons of heuristics to determine compressor run times, blower speed, doors/blending, compensation for highway speed airflow through the intake, etc., depending on many factors (cab temp, outside temp, difference between cab temp and desired temp, sun sensors). It's likely that (and from comments of people who tried it - it seems to be the case) adjusting the calibration will increase the blower output to your liking. Or, after adjustment, it might be only a few clicks instead of going all the way down - worth trying, I think.

If you don't want to mess with the OBD/programming yourself, a dealer can also do it for you.

 

I do have access to software and know how to use it. One of these days I'll have a look and see what options are available.

 

Hmmm...on a very hot day, with mine set on 70 auto, the fan increases to top speed within a few seconds after startup.

 

Once it settles there tap the temp control down to LO and see if something doesn't change. Mine does. Might be some damper action, too, IDK, but going to LO makes a significant difference on mine.

 

I'll test it again, but I'm pretty sure when mine is cranking at top speed in auto mode tapping to LO doesn't change anything.

 

I usually have mine in manual because I like to control the fan speed, so maybe it will work different in Auto. IDK, but it is still strange to me that going to LO changes the airflow. I'll try this again in Auto again next time I drive the Tundra.

 

Everyone is different. I enjoy the auto mode specifically because I don't have to constantly adjust the fan speed manually. It always seems to blow just the right amount of air to keep things comfortable. Kind of a set it and forget it deal.

 

Sorry, typo corrected. Our last 3 Toyos have been all the same with no way to jump from HI to LO

 

IMO to get max cooling and flow you’ve got to run in Manual mode (dont use Auto). Set your own fan speed, set your output vents, set A/C to ON, choose your temp (LO for max cool), set your air input (recirculate for max cool after warm air is vented using fresh) Lastly, ECO drive mode reduces compressor run time, use NORM. Our last three Toyotas have all had this same controller with Auto mode that just gives average cooling/heating.
