Whenever its borderline cold, my windows freeze on the interior side and its likea light frosting that is hard as heck to get off and i cant see out of it at all. I get it mostly ony my front and back window. I never saw the insides freeze on any other veichles except my own. Is anything wrong with my car, maybe an air leak or possibly something coolant related? I check my coolant a lot and i havent lost any since i changed my water pump but its still happening. Only other thing i can think of is i did use rainx on the inside and outside. Any ideas?

 

rainex on the inside? The regular stuff or the anti-fog?

I'd re-do the inside with rainex anti-fog and see if that stops it.

 

Frost on the inside is not normal. You have a moisture problem of some kind.

 

Do you have the heat on full? I always run my car with the HVAC set to Defrost / Floor, and with the temp set somewhere between half and full hot, use the rear defroster when needed (usually only initially when cold) and my windows always stay clear. The '89 Grand Prix I've been driving this winter is bad for the rear window constantly fogging up, but I was in the trunk the other day and noticed that there are some leaks through the floor of the trunk keeping it damp.....that's probably why the back window fogs up on the inside?

 

thats what it is just alot of moister in the car. a leakey t top or foolboard. i have the same prob in my civic with a leaky windshield

 

He said foolboard!!

 

My rear defogger makes quick work of the stuff on the rear board. The front stays iced for a while. I just remembered i have no antenna right now so that could be a hole to the interior thats about all i can think of.

 

DOH!
