After it has rained if I open my rear passenger door of my S205 I need to step back as a large amount of water comes out and soaks my feet. Inside of car bone dry. I have had the door card off and all dry inside. Used a flexible curtain wire on all drain holes at the base of the door. Removed and replaced the window seal into which the glass drops when window lowered. Checked both door frame seal and door seal for dirt and cuts all fine. Seal is in correct position and correctly fixed. Did find that the bottom of the seal around the door was wet but bone dry on vertical and top section. Have parked the car sloping up, sloping down and on the flat, still letting water out in all positions. No problem on any of the other doors. Anyone with suggestions for next step? Not causing any real problems other than to my OCD. Just have to stand back when door opened.
