Thread: Window fog. How to get rid of?

Ok for the past week when i get off work i can not for the life of me get the fog off my front window. Defroster does not clear it . heat, or cold. The only thing that clears it is running the wipers. even when i open the windows to make the inside match outside temp does not help.

Tonight i got so pissed off because i had to pull over because i could not see i hit my window and it cracked.

What the hell am i missing.
