Vent/side windows fogging up.

[skinnerd]

I know none of you guys drive yours cars in inclement weather…but I plan to with a new me 73.5 911T.

During the test drive it was cool (35F) and really raining.
The heat exchangers were doing a great job on the front windshield but the vent and side windows were hopelessly fogged up.
Couldn’t begin to use either side mirror.

What’s the cure?
A small fan?
FogEx applied to the inside of the glass?

Thanks for ideas.

I’ll post pics of the car when I get it in hand.

I lived in a really rainy part of the world.
With targa, I could slightly open the vent window and the airflow would solve every fog, all over the car.
I had to get used to a drip of water, and that was ok.

I could never tell of the anti-fog stuff would work.

Rules to live by:
Fogging comes from high humidity. And when warm air touches something cold.
Airflow is the best way to dry something out.
Always have a towel.

You can add a vent window to a coupe, 68 windows fit.
(They are $)


And if your car is already wet inside, then it is a real uphill battle.
I had to take my floor mats out in the rainy months, they would just keep moisture in the car.
