Honda Car Forum

I have a 99 Honda Civic (EX) and I have a problem in snowy conditions:

I start the car and keep the heater turned on fully (pointing to front
and back window) while i clear the snow. Then when I start driving, I
have the heater turned on - still pointing to front and back window.
However the windows incl the side windows turn pretty foggy very
quickly. Once the windows become foggy, i find it extremely difficult
to drive. what should I be doing?

When it rains, I keep the ac on inside, so the windows dont fog and it
seems to help.

Thanks,
GPN

you might to have your mechanic check the heater core, if it starts to
leak you get that fogging problem. you can also tell if you smell
coolant inside your car.

I keep the recirc off all the time. i dont believe i ever keep it on
when i keep my heater on. Am i missing something?

It's cold and dry outside. It's damp inside because of snow on carpet,
and your breath. Turn the recirc OFF, because you want to draw dry air
from outside to displace the wet air. It's isn't quite as warm that way,
but better than driving around in a sauna bath aka: Hyundai Pony

As mentioned in similar posts, METICULOUSLY clean glass helps a lot!
(inside!, though its nice to be clean on both sides)

There may be water trapped in the heating system because of the AC (it
should come on with the windshield defrost, to remove condensation.)

My solution for this is to drive at highway speed with the heater full
blast directed toward the windshield and driver/passanger with the back
windows open halfway. The windshield and front windows will steam up
quite fast, but will ultimately clear out in 4 to 5 minutes.

Very effective.

You're not using the AC in winter because you're thinking that you don't
want to make it cold inside.

Use the AC, and turn the heat all the way up. You'll get nice, warm,
dehumidifed (thanks to the AC) air flowing through your cabin. This air
will remove the moisture from the windows.

The problem I find is that once you start using the AC even for a short
while, your car fogs up quickly as soon as you turn the AC off. Also using
the AC zaps power and mileage out of your car. I usually just use defroster
at full blast with heat. some times with the window opened a crack.

One trick is to cover the windshield and the part of the hood nearest
the windshield with a tarp of piece of plastic that is stretched over
the windshield and trapped at the sides by the closed doors. Some of
the moisture causing the fog is from snow inhaled by the fresh air
intake which is now melting on the heater core. Any snow that falls
down past the wiper arms and in under the trailing edge of the hood is
going to show up inside the car in vapour form shortly after the
engine warms it.

Go back and forth between the heater and defroster until the windshield
warms up some. It should stay clear then. (Cracking a window will also work,
but that kinda defeats the purpose. ;-)
