The old girl (93 SC) just turned over 200k, and I have been fighting this problem since mile one. No matter what I try the car fogs up all the windows in cold weather. I did a search and found some references to "fog", "fogging", "defrost" and "defrosting", but nothing that is specific to this problem. When the weather turns cold enough to want to use the defroster the car just fogs up. There is no coolant leak as we have not had to add in for over two years, there is no sweet smell of anti freeze in the cockpit. We tried disconnecting the AC compressor, and it did not seem to make any differance with or without it. I checked the drain for the AC/Heater box and it is clear, I even flushed it out with a water/bleach mix to kill any possible mildew that might be holding moister. We replaced the climate control motor that operates the flapper. I am just at the end of ideas and need some guidance for someone that has had the problem and fixed it. Thanks for reading, shoot me some ideas........before I shoot the bird....uh tbird that is.
