I took the door card off a little while ago and all seemed well... until today when I went to hoover the car and found that the carpet around the drivers side rear floor was soaking!

I had a little look and found that when I pour water onto the rear quarter glass, at the join with the main window, water pours into the door itself and out through the door card!

I tested out the other rear door and it does the same, but does not come through the bottom of the door card....

HELP! (Please!)
