A/C window fogging and defoster

[thstone]

The fastest way to get rid of condensed humidity on the inside of the windshield is to turn on the a/c, set the fan at max speed, and select the upper right button to direct all of the airflow to the windshield. The a/c dries the air and the dry air will evaporate the water that has condensed on the inside of the windshield in a few moments.

The humidity is condensed on the outer side of the windshield ( at least in my case ).
Here in Florida it's still hot and hummed. So when the cold air is cooling the windshield, the humidity outside the car is condensing on it.

Coffinhunter,
I checked it out today.
When I press the left button, I get cold air at full blast.
When I press the right one, the cold air will still come out of the defrosting vent, but the fan speed will stay
the same.

One question. When you turn the AC on high, to you get foam flakes coming out of the vents?

The question is do you get the flakes.
(the stupid iPad won't let me fix my spelling errors )

That is exactly the problem. I end up using my wipers to see..

Which left button, and which right button are you referring to?

Nope, no flakes coming out of the vents. Just about everytime I get in the car the A/C goes to full since I have it on auto (gotta love Florida), and I have not seen that.

The "left" is the one I marked in the picture. The "right" is the one with the arrow up icon.
In my car both of them will blow cold air.
The reason I asked about the flakes, is because inside the AC air box there are flaps covered with foam. This foam is known to fall apart, and then the air flow inside the box, is not as it should be.
And yes, I use he wipers too
Sorry I couldn't help, but I can't figure out where the hot air is coming from.

By the way.
The way I avoid that, is not using the auto function and eliminating the defroster vent by pressing the center right button only.

That is what I have been doing too. Thanks!

Curious that the defrost button (left) blows warm air and I can't adjust it......
