My 2001 GTI leaks when it rains. My passenger side floor gets soaked, front and back. I can't seem to see any dry rot or holes in the weather stripping. Could it be coming in through the bottom when I drive in the rain, or through the wheel well or something? It doesn't look like water is dripping down the pillars by the windows so I don't know but my car stinks inside and mosquitos are starting to love it. Please let me know if you have the answer.
