Does the inside of your windshield freeze?

iyzmi · 01-02-2009, 10:06 PM

Every time I go out to my car after work on a cold day I have the joy of scraping ice off the inside of the windshield. I leave the vents closed and HVAC setting pointed away from the windshield but that doesn't help. Anybody have a solution for this?

Windows down?

Move to CA? I don't have that problem

Mine hasn't but my moms outback does sometimes when it's really cold out.

knockknockknock · 01-02-2009, 10:49 PM

If you have high humidity in the car when it is warm. Then when you park it in the cold, and it cools down. You will get frost on the inside of the windows. Most common is your carpets being wet, from rain/slush/snow tracked in by your feet.

It happened to my mom's outback too.
The air inside must warm up and create condensation then instantly freeze.

I wonder if it would be a good idea to bring those hand warmer packets to hold against the window.

id put a dessicant of some sort inside the car and open the vent off of 'recirc'

AC on (or either defrost setting which forces on AC above 32F). Don't sit in the car after it's off. Breathing adds humidity. Don't set the adjust to recirculate either. The main key is to minimize internal humidity.

iyzmi · 01-03-2009, 01:57 AM

Wait, you're saying to keep it on the windshield defrost setting and to let the outside air in? That's the exact opposite of what I've been doing, I'll give it a try though.

Badmunky · 01-03-2009, 02:21 AM

Yep.
Run the A/C and set to defrost with Recirc off. I.E out side air open.
Leave it like that when you turn car off.

That will fix your problem.

iyzmi · 01-03-2009, 02:27 AM

Whenever I forget to close the vents and aim away from windshield, and I leave the recirc off and set to defrost mode, I come back to my car to find the same problem... I'll try it some more times though, maybe it'll start working for some reason.

SeriousInquiry · 01-03-2009, 12:13 PM

Yes, every morning i wake up to f'in frost on the INSIDE of my windshield. You have to leave the windows slightly down, just a crack, and you'll be fine.

Bluefoton · 01-03-2009, 09:13 PM

check the carpets under the footrests. It might be a symptom of a completely soaked carpet.. either from a leak, or from melting snow from your boots.

In my old escort, this was the cause of the inside frost. Every spring I would have to lift the driver carpet up as much as I could and dry it over 2 days with the sun, heater, hairdryer, and whatever else I could find. All of that till I realized my rubber mat had a hole in it, allowing a river of melted boot slush to leak onto the upholstery.

Yes, that is exactly what you need to do (and, what I believe, your manual suggests too). Driving around with recirculate, you keep adding moisture to the interior every time you exhale, so the moisture/humidity builds up. That moisture freezes at night (for those of us who actually get cold). You can crack your windows, or let the air in from the outside...remember, cold air is much, much dryer than hot.

That's exactly what caused my truck to frost up on the inside recently.

+1. That's why your lips crack in winter, and not the summer.

my outback does the same thing sometimes

Mavrik · 01-03-2009, 10:48 PM

cycle the a/c on defrost, and make sure your drawing in outside air.
