leaky windows

I dont know if this happens to other people but it seems like my car doesnt seal when doors or hatch is closed. What I mean by this is when it rains or I wash my car my seats get wet and in the back my subs have condesation on them. Its really bad I hadnt payed much attention to it until I lifted the board and exposed my spare tire and noticed I had about a 4-6 in puddle sitting under the tire. Does any one know what this is. I noticed that my window on my drivers side doesnt seal completely but I dont see how that could make it that bad.

around the rim of the hatch there is that little hole to drain water if it builds up so maybe somewhere along that "path" there is a way for it to get inside

Dude, i dont know what it is! my 95 eclipse leaks on the driver side. It's not really bad tho.
