95 Tercel Fog Problem???

On my 95 Tercel it fogs up really really bad when i'm driving. Even when I go to my car in the morning when it's been sitting all night it's all fogged up... I'm not sure if this is a heater problem or just something that all tercels have a problem with or what but it's really bugging me. Has anyone else had this problem?? And if so what did you do to fix it??

I have a 96 Tercel and my windows fog up easily too. I find the best way to deal with it is to turn the heater on for a few minutes with the air recycling from outside not inside the car (not sure if 95 has that option) and then I leave one of the windows cracked open only thing I found helps with it.

check ur evaporator case, drain plug, and evaporator could be colgged. clean it if dirty and try the system.

real cheap solution i found was just to wash all the window with windex bathroom anty fog,,
work good
