Sure sign of a heater core leak. It may just be weeping a little at the moment.

Not necessarily. Don't ask how or why, but a radiator going out will have the same effect, even though the radiator is 4 feet ahead of the window and on the outside of the car. Generally, washing the inside & outside of the window with hot/warm soap and water to remove the sticky residue from the antifreeze, and then leaning with window cleaner will reduce the effects, but that is not a permanent cure.

My experience has been if one is going the other is not far behind. Best just to do both and be done with it. Nothing worse than driving along and all of sudden smelling antifreeze then seeing it all over your carpet.

I'v had the same symptom but it was the AC evaporator drain clogged and the condensate was ending up in the car. I got the drain fixed but still fogged for about a week so I treated my windshield on the inside with fog-ex, sounds kinda hoaky but it works. Good luck hope you get it sorted out. Jon Hanson
