The rubber seal between the front door and the exterior mirror housing deteriorates with age. This may cause water to enter the door. These seals are about $9 each at the dealer and I replaced them myself with instructions I found by Googling the problem online. You will need Torx head screwdrivers to remove the mirror from the door and replace the seal.
