Most likely the little rubber plugs that cover the drain holes at the bottom of the doors, these rubber plugs can get blocked with dirt very easily and will stop water from escaping through the drain holes, there was actually a bulletin from Honda years ago to remove them.Hi,
I have a major issue with my passenger door driver side wether strip.. (so I believe) whenever we get really bad rainfall the next day I have to empty out my drains otherwise it sounds like a titanic going down..
I have included a photograph of the gap between the strip and window. I think this is the cause because the other windows seem tighter against the strip.
Can anyone plz help me (hopefully before the next rainfall we get)
