Why does a glass of Ice water condensate in the Summer? Same reason your
windows fog up. Turning on the A/C in conjunction with the heater will help
dissipate the fog. The A/C puts out a dryer air than just the heater alone.
The heater will eventually dry up the fog, but it takes a while since it
depends on the coolant in your engine for heat. It's also a good thing to
run the A/C in the winter to stir up the coolant.
Don't have A/C? Then you're SOL, just kidding. Buy Rain-X Anti-Fog or that
pink wax stick you see at the home shows, and wipe it on your inside
windows. I rub the pink stuff on a terry shop towel and keep it under the
seat of all my cars for that purpose. Don't wipe your windows while
driving, pull over to a safe place and stop before wiping your windows.
Good Luck and Safe Driving!
