Hi Philip
Many thanks
It’s a long shot, but if you have a welding rod, or a thin stiff metal rod, could you not bend the very end into a v shape (small v shape), then slip it through and twist so the v is behind the clip, then gently pull until you feel some resistance, check to make sure it is the clip and then pull
I took the drivers rear door panel off and could see exactly where the water was coming out. The very bottom of the plastic where the black seal was not stuck to the plastic.
I pushed this inwards, so it sealed and then taped around the bottom plastic
Will have to see how it goes but now I know what causes the leak, will check next time if it happens again
Many thanks
John
