I bought a new 2007 TSX in the summer, the car ran perfect. I noticed once the weather got a little colder out, i had Ice forming on the inside of my car, all my windows and windshields. This problem has occurred weekly throughout winter. I have all my windows closed, the AC is on defrost but there is still moisture getting into my car.
I took it to Acura and they checked all the seals in my car and found nothing wrong, but if moisture is still getting in, there is definitely something wrong.

Anybody have any ideas why this is happening or solutions?

Thanks

 

Clean your windows with water and scrub it dry. Maybe try some of that rain x window anti fog.

 

Are your carpets damp? There's definitely more moisture in the car than there should be. Cleaning the windows won't fix that.

 

Agreed. There's got to be water inside somewhere; condensing then freezing.

 

Well, not really as much as you may think.

Let's take this in a new direction for a second:

lemon10: Where do you park you car?
How warm is it during the day?
How cold is it at night?


Here's where I'm going:
Just your breath and your presence in the car, with or without the air
on can put moisture into the air. There's going to moisture in the air
no matter what, plenty to condensate on the windows.
Condensation happens when there are two adjacent air spaces that are
of differing temperatures.

If there is a temperature difference between the outside and inside of
the car, it could create condensation, and then it could freeze if it's cold
enough to do so.
The interior being so tight will only contribute to this.

Ever try cracking one or a couple of windows by an 1/8th of an inch?
Or maybe airing the car out before parking it?

I agree, this probably should not happen, but there may not be a water
source to find on the inside, it could be a rapid temperature change...

 

if hes getting ICE buildup there is moisture somewhere in the vehicle. bad heater core even. get a second opinion from another dealer

 

I've lived in New England my whole life (more years than I care to admit to, and that's allot of winters) and parked a wide variety of vehicles inside, outside, and any combination of both, and I've never encountered this problem. If there is actually ice forming inside a car, there's water in there somewhere that's evaporating, condensing, then freezing. There's no way there'd ever be enough ambient moisture in the car to create this problem.

 

I park outside in a parking lot at night
During the day its anywhere from 0- -10
over night it usually will drop by like 5 degrees.

I tried leaving one or two windows cracked a couple times, I still got Ice on the inside by the morning.

I think i will take it to another dealer and see if they can find anything.

I feel like i bought a defective car.

Thanx for the help

 

Don't listen to those who say "this shouldn't happen" or there's some kind of mechanical problem. The exact problem has happened with the last three cars I've had--1991 Toyota Corolla, 2001 Nissan Maxima, and now my 2005 Acura TSX. Like you, I have leave it out at night. All you need is a little bit of moisture from anything--your breath, a damp umbrella, snow--and cold temperatures at night, and you get an ice storm inside.

In the winter, with any snow on the ground, it's nearly impossible to keep moisture out--there will always be a few snowflakes getting in from your boots, etc. It melts or vaporizes, temps plummets, and its condenses on the windows. And endless cycle, unstoppable.

I've tried putting "Damp" (the white crystal stuff used for dehumidifying closes) in a vented basket. This helped a bit in the past, but is doing nothing for my TSX. I've sprayed the inside windows with Prestone "Ice Prevent" liquid, which, admittedly, is a bad idea since the stuff is poisonous. Nothing seems to help.

I'm thinking of investing in a very expensive car cover that might do something to warm up the car enough so it doesn't freeze up, since this is driving me crazy.

check your carpet under your floormats. Mine is almost always wet. I work at a detail shop so I just suck up all the water that accumulates from melting snow. If this is your problem, you could get some rubber mats.

 

I park my car outside EVERY night and I have never had a problem like this. I can build a snowman in my backseat and not have a problem like this. Trust me...a wet umbrella or water from your shoes will not cause this problem. I leave open bottles of water in my car overnight and do not come out to ice in the morning. (after dropping the cap under the darn seat. Why is it so hard to get bottle caps out from under the seat of the TSX?) Anyway...there os some problem somewhere. Just be persistent with the stealership...they'll find the problem eventually.
