Low coolant?
Cooling fan not working?
If you have the control set on Max or recirculate, it will recirculate the cabin air causing the windows to fog. Set it to Normal or for outside air. Do you smell something sweet? If yes then there is a leak in the heater core and this will cause fogging.
you may have your switch on your heater control set to recirculate the inside air. it should be set for outside air recirculation
Either you have the air vents set to "recirculate" which means you are running the same air around the vehicle without drawing any fresh air from the outside, or your heater core is blown.
The simple solution is to set your heater to recirculate so no new fresh air comes in. If it is coming in through the doors and such you may need to replace the seals.
You have the system set to allow outside air to circulate into the vehicle. You can change this to the recirculate mode which will only circulate inside air. Look for the button to change the setting.
Try closing the air vents or set them to recirculate before switching off the engine.

Turn the defroster on. If you have a separate AC switch, turn it on also. The AC should come on with the defroster automatically, but might not. If no AC, set the vent control to outside air instead of recirculate.
It's called a "vent", as in "ventilation." They generally take air from outside the car, unless you've got it set to "recirculate." Most likely air is being forced into the system because the car is moving, and that's the air that's blowing through the vent even though the fan is turned off.

The heater is set on recirculate the air of the cabin. Set it on normal (from outside the car) You have to move a button on the console to take air from outside the car or else the air will be too moist from all the humidity that accumulates in the cabin. Also the engine temperature must be hot enough. I usually run my car at least 5 minutes driving it downtown before it is hot, during cold winter days.
yes, it can overheat and set on fire, heat up your hair and set it on fire and set fire to your pillow. Obviously.
