If the mist is forming on the outside, won't the auto wipers clear it as necessary, just as they would rain?
How does the mist form on the outside on a rainy day, when the screen is wet anyway?
I'm obviously missing something!
Only if it gets as far as the rain sensor, which is usually part of the mirror mount. The reason the mist forms is that IT is cold (having gone through the A/C kit).

The problem is, the screen is becoming significantly colder than the ambient temperature and moisture is condensing on the outside. A little warm air would help, if necessary.
I have tried. the fog will still form.

I have attached 2 images for your understanding:

Meanwhile, I'm finding a way to block the outlet, which is aesthetically pleasing to the eyes. Any suggestions?

Thank you very much.

Have you tried cleaning the outside of the window thoroughly with a proper de-greasing glass cleaner ?

In my experience road film deposits (which are largely oils) can make glass prone to fogging but be otherwise invisible. I would also clean the inside of the glass.

I agree with what Mandrake (Simon) says. It is a very good idea to make sure the glass is spotless inside and out, as any dirt is a condensation seed point. I also use Rain-X on the windscreen to help keep it clear when it is raining.
