>it's really not that complicated

After reading this I am still not sure which one to use. They seem to both work.




Both work, one is just faster than the other. The post you replied to seems to imply that cold air is better in the winter, but that is absolutely not my experience.

When I get in the car in the morning, the air is already cold. No amount of more cold air from the vents will clear that. What's making it fog up, is the moisture I'm exhaling. More cold air is not going to fix that unless I drive with all windows down. So the only reasonable option since AC don't work at low temperature, is waiting for the car to heat up.


tl;dr of my post: turn on AC and blast hot air at the windshield. if that doesn't work in the winter, open your windows. if it doesn't work in the summer, it's because the fog is on the outside of the windshield; use your wipers.
