Holding a small inspection mirror under the opened door is an easy way to examine the door drain holes for clogs. The door window seals just can’t prevent rain water from getting past, so the designers plan is to not even try to stop it, but instead let it go inside the door, then it will drain back to the outside via small holes we’ll drill in the bottom of the door. Works great unless the holes get plugged up.
