correct about unplugging the drain holes, water needs to flow there to escape. Foliage residue tends to get trapped in there if you are near trees. A tip if you have a sunroof, as well, you might check and clean the drainholes around the perimeter of the open sunroof. They need to drain, too, and if you're getting some residue in the door it may well be around the sunroof drains.
