Condensation on the inside of windshield

Modshack

Uhhh....Your breathing is filling the car with moist air. Don't use the re-circulate mode unless you absolutely have to.....(like being stuck behind a Hog truck or something..)

The car was outside my building for 8 hours building up that moisture/condensation, had nothing to do with my breathing. I'm talking about fog either, actual, large drops of water.

I thought that may be the issue, but my GF's car had her vents closed last night and had nothing on the inside of her windshield.

Of course it did...You drive around with the car closed up and the re-circulation on, then close it up for another 8 hours? Where do you think the moisture came from?

Trust us...Turn off the re-circ and your problems will disappear

Made sure the vents were left open tonight and checked my car along with the 6 other cars in my parking lot after 5 hours.

My car was the ONLY car with moisture completely covering the inside of the windshield. I turned on the AC full blast and it got rid of the fog, but not the condensation. I tried heat as well, again, nothing for the condensation.

Again, this was not happening before this weekend and was not happening to any of the other cars (including a 83 t-top 280z and a 2006 G35).

Not sure why so many people are telling me it's normal, but it isn't.

EDIT:

I went to the dealership this morning and reported the issue. The guy, again, said it was normal and that "every car in the parking lot did the same thing". He opened up one of the cars nearby, and sure enough...no moisture near what I had. He said he'd get back to me tomorrow. I guess we'll see.

Sounds like:

1) your car is saturated from running with the re-circ on. Next sunny day, open the doors and let it dry out for a few hours. In the meantime run with the AC on and the vents open. AC acts as a dehumidifier.

2) You've got a leak and the car is wet inside resulting in the constant high moisture content. If none of the carpets are wet, take a gook look in the spare tire area..

This got me thinking, so I investigated a little today (resulting in getting NO sleep...been up for 25 hours now) while on the phone with my audio installers and Zenclosures.

No carpets were wet that I could tell, but then I moved the seat all the way forward and checked the area behind my driver seat....SOAKED!

Apparently, a few weeks ago my audio installers left an unfilled hole in the firewall without it's grommet inserted. One evening recently, when it rained, the water dripped from the windshield straight down to this opening, ran down the side of the floor pan, and "settled" underneath the carpet behind the driver seat. The water eventually drained out, but left the carpet with PLENTY of moisture to make the inside of my car a steam room overnight as my car sat in front of my workplace.

I took the car to the installers. They replaced the grommet, wet-vacc'd the carpets, and it appears to be as good as new.

Thanks for all the different ideas, and special thanks to Modshack for getting the gears in my head going.

Glad that helped and you got it resolved!...
