I have a leak which is making the drivers footwell damp after heavy rain. After much research on here the culprit seemed likely to be the door liner. On removing the door card that turned out to be fine but I still taped the edge up with duct tape just be be sure. I then sprinkled talc over the door seal to see if that gave me any clues (another helpful trick from these forums). Turns out the water is entering through the door seal roughly level with the bottom of the windscreen as per arrow in photo.
Do I need a new door seal or is there a trick to revive the rubber?
