Unhappy Windshield Whiteout

Hello Everyone,
I have had my windshield fog over in less than a minute several times now. It's usually when running the AC and we run into a rainstorm. Does anyone know a way to prevent this? It happens quickly and I have near zero visibility. I obviously pull over and wait about 5 minutes for the defroster to clear the windshield enough to see again.

I have 2 small fans up top that speeds up the defrosting process.

Yup! You need more airflow up there.

It's my understanding that the defroster is actually the AC redirected to the windshield. Condensation occurs on the warm side, think of an icy glass of beverage.

I'm not at mine to check but is there a dial setting for both dash and windshield?

Didn't JC Whitney used to sell a defroster unit that you could add to the top of your dashboard?
I think that they really weren't much more than a heating element and a blower. They could put a fair amount of warmer air up onto the windshield, and get rid of the fogging.

Rain-X makes a product called Anti Fog that you put on the inside of your glass to reduce fogging. Walmart, Target, Autozone, Amazon..... all carry it.

There is also anti-fog cloths you can buy and just keep one near the flight deck.

Check to see that the dash vents are pointed toward the windshield. The dash vents rotate manually and if they aren’t directed toward the windshield you won’t have any air to defog the glass. Adding a little heat when the defroster is on will help too.

Make sure your AC compressor is actually running. If all is working correctly running the AC, even with heat mixed in, should de-humidify and clear your windshield. From your description, its sounds like your compressor may not be running, which would allow exactly what you describe to happen.

I was going to have the Flight Engineer/Wife man a squeegee.
