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.

Why does the inner surface of the car window foggy on a rainy day?
They fog up when water condenses on the surface. If the air inside the car is warmer than the outside temperature you will experience fogging of the inside of the windows. In extreme humidity the problem is worse. You can also see fogging if the heater core is leaking. To dissipate the moisture turn on the defroster.

How do you know for sure its the heater core?
It's usually pretty subtle at first, you'll probably notice your windows fogging up or smell coolant inside the car. If it starts to get really bad you'll see steam coming out of your vents... Get it fixed before it gets bad! The last thing you want is coolant all over your car and inside your ducts - not to mention that smell!

Heater core blew. disconnected heater hoses so heater doesnt work but car seems fine. moisture from all that water and coolant inside the dash is still fogging up car as it sits tho. how to dry it out?
most effective way would be to place a de-humidifier inside the vehicle,closing all doors/windows.The moisture is concentated in the soundproofing. If your windows fog up, make certain that your vent position is on 'fresh' air to blow the outside air in, rather than 'recirculate'. That will aid in drying up the moist inside air.
