Thanks very much. Those are some things I can check myself. Anchorage Ak, by the way. I do know that the rubber gasket around both back doors kind of hangs where it shouldn't. I suppose that could be contributing. I think I smell fumes coming through the vents sometimes. Does that suggest anything to anyone?
I have a 1993 Loyale Station Wagon and I'm getting an exhaust smell inside. Any ideas? (I find myself driving with the window open and this is Alaska in the winter!)
