Essentially, you’ll switch between heat and air conditioning. When you do that, you suck the moisture out of the air and aid in defogging. To use this trick :

1. Turn the heat on full blast to eliminate moisture in the air
2. Turn on the A/C to make it more arid
3. Switch back to heat, and switch off the air recirculation button (the one with the arrow twirling around the inside of the car)
4. Open the windows. Not a lot, since it’s clearly cold outside, but enough to let cold air come into the car, drying it even more
