How to Prevent Inside Car Windows From Icing Upby Michael G. Sanchez
Inside icing or frost is a result of too much moisture in the car, usually from melted tracked-in snow. Chronic icing indicates a leak, such as from a window seal, sunroof or heater core, or from a hole in the floorboard under the carpet.
Eliminate Moisture for Less Icing
Run the defroster on high and turn on the A/C compressor. Use rubberized carpet pads you can remove and dry out. Check for wet spots in the carpet and track down where the water's coming from. A sweet smell may indicate a leaking heater core.
