This is a question for you fellow 70's series owners. My 1998 S70 has had some AC/Heat issues lately. Any help from others who have similiar experiences would be helpful. When I turn the heater on I am geting blasted with a foggy haze that reaks of coolent. Kind of a whitish haze/fog. It is like someone put a fog machine in the car. This also happens with the AC on unless I have the temp dials set at the coldest setting (60 I think). At the coldest setting everything works fine. I have had the AC set to the coldest position for the last week to avoid this phenemonon. The closer you get the dial to the heat the more the fog machine effect kicks in. Could this be a heater core? Any Ideas? Also costs would be helpful if anyone has had a similiar problem fixed?
