Car Forum / Honda Cars / January 2005Foggy windows in snowy conditions
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 have a 99 Honda Civic (EX) and I have a problem in snowy conditions: > [quoted text clipped - 10 lines] > Thanks, > GPN --------------------------- 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 'Curly' 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? GPN > I keep the recirc off all the time. i dont believe i ever keep it on > when i keep my heater on.

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. > I keep the recirc off all the time. i dont believe i ever keep it on > when i keep my heater on.

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. ;-) |
