Never before, but suddenly my right rear door leaks water during the
rain and car wash. The water is entering the panel on the bottom in the
middle. Somehow, in the center door post is the seal loose or worn out.
That door was very rarely used.
Do I need to replace both seals on door and the frame?
Door is still flush with body? Seals are easy to check. Get a strip of paper
( ~ 2-3 inches wide) and put between door and body as you shut door. Pull
on the paper, if it just slips out with no friction from seal, the seal is
malformed or door needs adjusting. If when you pull the paper it is held by
the seal, the seal is ok. Check at different points around door.
I'm confused about where the water is coming in. First, I'll review
some terminology. You have three roof support pillars on either side
of the vehicle. These are referred to as A, B, and C pillars from the
front to the rear, with the B pillar being the one between the doors.
If the water is leaking out of the bottom of the interior door trim
panel, the water deflector (a piece of very thin plastic stuck onto
the inside of the door behind the trim panel) is likely torn, loose,
or missing. The door is designed for water to run through it, so it's
important for this plastic to be intact and in place to keep water out
of the car.
If the water is leaking from behind the trim panel on the B-pillar,
you should remove the B-pillar trim panels to further investigate the
source of the water.
Thank you for your time, will investigate more, it's not easy to find,
appears that it seeps thought the middle panel. (When I pour water in
the handle hight between the doors, then it leaks, not from the top at
all). Then in runs on inside door and over the panel to inside. Not sure
of the proper body names. Only I can see, the water seeps over in the
joining plastic cover (the lowest part of the door opening), The door is
in perfect condition. Only thing remaining are those two seals, one on
the door and one on the frame itself. There is nothing else there, is it?
