Windshield fogging up

Alright guys, I'm either stupid or this mustang is impossible. I have a 14gt with 4k miles. I absolutely cannot drive at night with my windows down without the windshield fogging up. I've had an Escalade, Ram 1500, and a few other and I've never had an issue. What's the secret? It doesn't matter if it's a 60 degree cool night or a 80 degree warm night, it always fogs like crazy. Is it where the engine is throwing heat into the glass!? I'm about to give up 😖

Mine does it after I shut the car off and it's sitting for a bit. Does it happen while your driving?

Oh yeah, if the windows are down at night it's fogged. I've sometimes successfully unfogged it by turning the heat all the way up and using the defroster. But it made the temp in the car at least 98 degrees.

Your issue is the same issue I've always had, the issue with the fogged windshield issue. My issue has been an issue for a couple years since I was issued the car. I'm not sure how this issue can be fixed, was thinking the issue could be a sealing issue with the windshield issue. Anyone else had this issue?

Mine does it sometimes when parked. I have seen it a little while at a long red light. Not while in motion. Maybe try some rain x. I actually hand wax my windows. Acts like a rain x.

I have experienced this a few times when it's really high humidity. First suggestion is a super-clean windshield. Fords tend to emit some kinda gross window scum that's hard to get off. I like to scrub it with Dawn dish soap to remove the oil film, followed by a good glass cleaner, like Invisible Glass. And second... Finding the perfect temperature on defrost. But if you are in real humidity, it's tough man

You just need to run the ac with it pointed to you and the floor NOT the upper vent. It's an easy fix.

I get this all the time in the summer. It's from the humidity. You have to turn the defroster on and the heat both as high as they go then put your windshield wipers on for a few wipel and after a minute or two it will go away. Once it clears up you're good to go. It only happens occasionally, but man it sucks when it does. Took me forever to figure out what to do.

Heat from the engine bay coming back onto the windshield, plus high humidity is causing this. The design of the car; low swept windshield and small engine cockpit are not like the bigger SUV's.

In the summer, roll up the windows and turn on the air. Unfortunately, these cars are not suitable for windows down driving when the summer humidity exists.

My Ford ranger does this as well.

Haven't had any problems with the windshield fogging up and I'm in one of the most humid states in the U.S.

Where is this?

I live in central Florida; we are now into our hottest, humid months, with 98% humidity. I can say with certainty that my windshield will fog up at night if I do not run the A/C in both my Mustang and Ranger. During the day it is not a problem though; the heat is!

My issue is the fogging issue on the inside of the windshield issue. That's the issue I'm talking about issue, not the issue of fogging on the outside issue. The second issue is that I think some of you think the issue is on the outside issue of the windshield issue, if that's the issue you're thinking of, that's not our issue.

Mine only does it if the windshield is dirty on the inside. I just turn on the defrost to get rid of it.

What drives me crazy about windows down driving in the Mustang is the wind noise. I never heard it this loud in my Trans Am coupe. I like riding with the windows down especially when it's nice out.
