Why does cold air on my TOYOTA 86 come off as hot ? Without AC on.

[Braces]

What Humfrz said. Just open the window. I personally don't trust the air coming into the cabin through the outside regardless of filtration. I feel like I'm inhaling the exhaust coming from the car in front of me. In the Phoenix summer .... recirc max A/C. In the winter .... open window. As for fogging .... correct me if I'm wrong, but it probably gets really humid in Argentina? Right? I'm sure that adds to the inside fogging. Again ... open the window and allow the humidity to escape.

Can we all get back to driving the car now?

Then about the windows getting steamy as soon as someone gets in or you start breathing, does this happen to you as well ?. Thanks adam

On occasion that occurs, but it's definitely not something that is consistent enough for me to warrant any attention to. I am sure that has to do with the climate differences between where I am at and where you are though.

Mine does it too. Pretty much what others are describing. My previous cars would blow air that was at most a couple degrees warmer than outside, this thing is at least 5-10 degrees warmer when the engine is up to temp. Not a problem for temps below 70 degrees but rather annoying in that 70-90 degree range when on previous cars I could save some gas by not running the A/C. This is regardless of speed, it's always warmer after the first couple minutes. Like others have said, gotta bite the bullet and turn on the A/C or crack the window, which I kind of like, I didn't enjoy window down driving very much in my last car with hand crank windows.

Do you have to repeat the process after a certain amount of time or does it work for the remainder of your trip? It sounds like you could save yourself some time by just hitting the A/C button for a few minutes, it seems like it would accomplish the exact same thing.

I seem to remember anecdotally that a lot of 'high end' performance cars in the past had shitty HVAC because it wasn't a priority. But I can't back that up. I'm lumping it in with the crickets as a quirk.

Other cars don't necessary have a better design, they have different priorities. This car is designed to be lightweight, so they use less insulation and Little focus on placement and thermal isolation of the HVAC vents
I too noticed that this car blows a lot more heat than ambient outside air when the dials are all on cold and outside air. But only after its been sitting, after being run.
If you first start your car in the morning and turn the controls too cold and just vent, the cold air coming out of the vents will be blowing outside air very similar to ambient outside temperature. for as long as the car is moving. Get in traffic or turn the car off for a little while and it will blow hot air due to heat soak from the cowl and firewall.
So it appears that the system does close off the air properly and it is a heat soak issue because of the cars design and design priorities, not because it's necessarily a bad designed HVAC system.
As mentioned recirculate will stop the unwanted heat from coming in..

Well whatever the reasons for the design, it's what we got.

There is no "fix", only ways to deal with and reduce the occurrence. For the guy wanting pure cold fresh air...it's not gonna happen like the old car. The vent trick only "helps", it doesn't alleviate.

We have different weather systems between us, so my personal experience may differ. The average day here is humidity in the 80-90's without rain. With that said I must begin using the compressor about a month sooner than usual(which is already 8-9months a year!).

As long as the weather isn't horrible, it hasn't been too bad using the vent method, but not perfect like before and never will be. When you reach this weather point, turn on the A/C or open the window.

Not the end of the world, but still worth noting since it can be done by other car makers.

So for cold air to blow without AC this is the only solution ?

1) temp all the way hot
2) turn vent to 1 of the 3 defog settings(last 3)
3) temp back to cold, wait a few seconds
4) vent back to...

Thought I was going crazy, didn't know other people were having same issue. My dual climate system seems like it's hot on ever temperature setting beside "LO". It's winter out and I it'd be nice to not be on the lowest setting but not be sweating when I try to turn it on click.
