If it is too ferocious just use setting 2 rather than 3. You can cycle through by repeat pressing the button. It will cool quickest and then turn down itself on 3 but a lower setting will still get there in the end.
My air doesn't seem to change between setting 3 and 2. Only if I move "Auto" to the lowest setting does it change the fan speed. Not sure if it will slow down on its own on setting 3 because I have temp set to LOW as it's summer and I'm in Phoenix. Does seem odd thought that setting 2 and 3 blow the same and only setting 1 immediately changes the fan speed? Is that the same for everyone?

Have you tried leaving it on 3, letting the vehicle cool off quite a bit, and then trying 2?

Mine are definitely different.

Mine is set to auto at 70. When coming out of the garage the fan will change fairly soon. If the car was parked in the 110 degree day in a parking lot it will obviously take longer. We don't have very high humidity which will make AC less efficiently. I give my MY24 AC a very good. As far as the conrols I don't find any problem. I think people think things should work fast like their gaming computers with mega power.

Arizona has to be the state where more forum participants live than any other state in the nation.

Yes, it does work really well. My only issue/question is the difference between the high and medium setting on the AUTO function. Not sure if I have a problem or not.
I hear you. But why is there even a speed setting to change if that's. the case? When Auto is on "low" the fans definitely slow and blow a lot less. Just doesn't make sense to me. lol. In any case, the air works really well and even here in Phoenix, within a few minutes of driving, the cabin is fairly cool. Comfortable at least! Thanks again!
It may not work in AZ but in the northeast we can use the flow through ventilation (mostly Spring and Fall) instead of A/C. I would imagine the fan speed choices are for fine tuning the flow through effect. Personally, my A/C is on all year, so I haven't used the flow through feature for decades. And top up or down the A/C is on. Glenn

I still don't understand why if you are using the A/C on AUTO, why you are also changing the fan speed. That should happen automatically. What is your temp set to? If it is very low, the cabin may never cool enough to slow the fan speed. But no matter what you set the temp to, when you get in your burning hot car, the fans speed should be crazy fast and in a few minutes slow down. If you drive long enough, they can slow so much that you may not hear them. I might be crazy, but I think the number selections and AUTO don't have anything to do with each other, and you use one or the other. Changing the fan speed manually is defeating the purpose of AUTO. Good luck! Glenn

Just seems odd. I CAN put AUTO on the low setting even when I first get into the car after it sitting all day and it will blow cool, but on a much lower fan speed. I guess I just expected the different settings to DO something different, especially since the low setting actually does. That being said, I have the temp set to LOW so I'm not shocked that the air system might not BE able to keep up enough to slow itself, at least this time of year. Again, if the LOW setting didn't do something completely different from the other two, I would figure the same as you are saying. Just seems odd.

Well, I guess that if that's how the AUTO setting is supposed to work then I need to set the TEMP up a bit instead of leaving it at "low". Or maybe if I'm not going to use the temp settings that way I should just use the "Max A/C" function and control it by speed of the fans? Is that what you're saying?

If you're setting temp to "low" you are basically setting it to max AC. Low temp setting is something the car can never attain so the fans stay full blast. If you want the auto setting to adjust the fans you have to set the temperature to a reasonable number that the car can attain in a reasonable time frame.

Yes, for the most part. Since I'm in the Northeast, I don't have much use for Max A/C. That would be overkill for me. It may work similarly to recirculate and only recirculate the cabin air, not bringing in outside air, which can make it easier for the A/C. It might be helpful in AZ. The only drawback may be on long trips; the air won't be as fresh. Glenn

Aha....I think I get it. Didn't realize this. I use the "AUTO" setting on all my cars! lol. Welp....live and learn!

If you live in Arizona drive to North Dakota and by the time you get there the interior of your car will be cool enough for you to notice the fan changing speed. :like: Seriously, the fan speed doesn't change speed unless the air circulating inside the cabin has cooled sufficiently. The same is true for heat. The fans will not slow down until the interior has heated sufficiently. The fan speed is directly affected by the temp of the air in the cabin. As I suggested in an earlier post if you move north this isn't an issue. Good luck! Glenn
I did some experimenting today. And yes, the fan speed does change with temperature. Put it on auto high, then toggle the temp up and down. The fan speed will change. I think the issue is people crank the temp down to the mid 60s thinking it will cool faster. But that just means the fans are going to blow endlessley until the cab temp somehow drops that low which is highly unlikely. If you put your temp to the low 70s or upper 60s, the auto feature will work.

BANG ON! That'll do ya! That's what I've been trying to explain. Being in AZ you guys must live with frantically blowing fans a lot. Anyway, glad you got a handle on it! I hope Sinthor 5.56 reads your post and Kevi's post. Glenn
