quick question. why/how does your window freeze on the inside? i have never been able to answer this question. this happened to my old car as well.

 

Humidity cause condensation on the glass and then freezes when cold

 

so then is this because i have the heat on and then when i leave the cold air gets in?

**what am i doing to cause this? cause its a pain in the but.

Its just like when you go to subway and its cold outside the windows get foggy.

 

Most likely cause is going to be a bad window seal or door seal and worst case would be a poorly installed windshield from the factory. I live in FL and this time of year if i leave me window crack even a hair then my windshield in the morning is covered. http://www.homeandbeyond.com/prod-0119166.html I used a wax bar and covered the windshield ended that mess

 

hmm... hot air contains more water vapor than cold air, so when u park ur car and close the doors in an afternoon, warm air is trapped inside. Then over the night, the outside environment causes the temperature on the windows to drop, thus slowly cooling the warm air that was originally inside your car. The water vapor in the air inside the car tries to escape the air when temperature cools and it starts trying to stick to any surfaces it finds. The water vapor condenses on to the surfaces and freezes when the temperature drops belowing the freezing point...

at least thats what i think is true.... not 100% sure tho....cant really remember anything from chemistry class last year

 

checkout that stuff in my post I had to use something similar on my old dutsan truck and it worked perfect

 

Yeah I dont get that either. I went in my car and there was actually ice building up on the inside. My friend went in my car and he was like "how did that happen, did you have the windows down or something?"

 

Instead of worrying about the windshield being installed improperly start with something simple. Are you carpets wet? If so, where? A lot?

 

Air contains water vapor, your breath contains water vapor, air pumped into the car through the vents contains water vapor. Warm air has a higher saturation point than cooler air. Water also has adhesive properties. When it's colder outside than inside the water molecules that come in contact with the cold glass on the window will adhere and condense into droplets. If the inside and outside temps are similar then you won't have much condensation. If the temperature outside is cold enough then the water will eventually freeze. Then when you leave the car and the temps inside drop it reduces the likelyhood that the water droplets or ice will warm up and dissolve in the air again.

You're not doing anything wrong, it's just temp differences. As long as your car doesn't smell mildewed, and you don't have wet carpets or anything, it's probably 110% normal.

well i must say my carpets are wet from the snow. mostly just the driver side. but whose isnt in winter?
