So I have had this leak for a long time and tried many things to try and fix it. I know it isn't from the cowl being clogged up. I had a puddle the floorboard today and i ran my hand around the inside of the door and realized that the bottom of the passenger door was wet. I ran my hand around the entire door and no where else was wet. Does that mean that the door seal is bad? If not what else could it be?
