Re: Fogging Windows

Gary, You mentioned you were driving in snow, sometimes what happens in 
my 5K is that snow somehow enters into the air intake under the cowel 
underneath the hood, and when the car reaches a certain temp. it creates 
a very moist air which is blown into the car via the heater blower, and 
warm moist air on very cold windows does what? your right fogs up and 
fogs quickly. I also noticed it only did it when driving, more snow must 
enter the intake when it's stirred up while driving. The fog in my car 
only lasts for so long until my heater gets warm enough to defrost it. I 
must also agree with other members when they say "check your heater core" 
if it does it all the time, take a paper towel and wipe the inside of 
your windows, a greenish-brown film means problems.
					Hope I could help.
