In Houston, the weather can be quite hot and humid after a rain storm. The Honda Fit has a poor defogging system? I tried all different defogging modes, and temperature settings. Yes, I use the AC to reduce the interior moisture, but the fogging is on the outside. The windshiled starts fogging at the bottom to which I use the wipers to clear it. Both driver side and passenger side windows fog up too, but I don't know of a way to clear that. The fog is located around the outside rear view mirror. It can be safety hazard because the fog blocks the mirror from view. I tried clearing the fog by rolling down the windows, but the window seals do not wipe the fog off. Anyone have the same problem, any suggestions?

 

Fogging outside of the window is hot humid air facing the cool areas of windows caused by air-conditioning. You may reduce the side window fogging by closing the air vents on both ends of the dashboard or redirecting them away from the windows.

 

Thanks! You are probably right.
