This is not a problem unique to Contours; just more aggravating than most. Seems as tho most drivers keep all windows shut, maybe breathe too much & fog up the windows. Check out the young-sweet-things driving Neons; its a wonder they can see at all.
When cars had vent windows, this was rarely a problem. Opening the driver's window a bit does promote air circulation within the vehicle to release trapped humidity but so does running the defroster (cycles the air conditioner to dry the air).....my$.02.....
