The reason your windshield fogs up has everything to do with the temperature inside your car versus the temperature outside. When you get into your car on a hot day, the cool air conditioning hits the warm glass of your windshield and causes condensation. The same thing happens on a cold day when you crank up the heat; the warm air from your vents hits the cold glass and creates moisture.
So what can you do to keep this from happening? First, try setting your vents so that they’re not blowing directly onto your windshield. If that doesn’t work, crack open one of your windows so that there’s some airflow going across the surface of the glass. You can also try using an anti-fog product on your windshield; just be sure to follow the directions carefully so that you don’t damage your windshield or hinder your ability to see while driving.
