Windscreen fog problem in vw passat?

Answer 1

When i have a few people in my car

(when i say few i mean more than me) i cant see anyting out of my windscreen or my side windows...

Even if i put my blowers on the windscreen and on full whack i can only see in about the bottom 4 inches of the windscreen which means i have to drive like an old granny

any ideas on what i can do or how i can solve this problem??

Chances are when you were having this problem, it was cold outside. That many people in the car breathing out moisture causes this when the moisture comes close to the window and condenses onto the windows causing the fog. If you have a recirculation button, turn it off as it is recycling the moist air in the car. The recirc button is for the air conditioning. Once that is off, the heater will draw cool dry air from outside, through the heater, which will clear the fog. It will work even faster if you open the front windows an inch. If you always drive with atleast one window open a half inch, you should never get fog or frost inside the windows.
