Hello all...

I've done just enough searching to see that it will be a difficult
subject, but I'm curious if anyone can tell me the purpose behind these
slotted black vents in my doors. They are rigid, textured plastic, they
have slots (in two columns if memory serves) and in the back there is a
sheet of black rubber with little oval flaps cut into it. There is one of
these vents on each side, and on the driver's side, it is positioned
directly opposite of the weight rating placard (on the body, not the
door). It is just above the striker bar.

If it matters, this is on a 1990 Daytona. I don't recall if my '89 had
them, but I suspect it did. I don't see really any purpose in them aside
from pressure equalization to let the windows close properly, but if this
is the case they do a poor job.

Any ideas?

TIA,
CJ

I don't know about your specific model, but many cars (including my 1998
Caravan) route some of the air conditioning air through a vent that pushes
up against the door - right at the spot you're describing. The air then
goes through some ductwork in the door and exits in a small vent in the
rea of the door facing the driver/passenger's back and seat.

So... your door may have the slots in place for this (simpler to build one
door style) even though it doesn't actually have air flowing through it.

Those little vents are what keeps you from blasting the glass out of
windows.
Cars are mad so air tight when new, that if the vents weren't there
the windshild, backglass, or quarter glass would pop out or at least
dislodge itselt over time. the vents allow the pressure to escape when
a door is closed. at one time your car was (maybe still is) this air
tight.

Hmmm... thanks for the reply. Makes sense. I wish my car still was this
airtight, but unfortunately the rear glass seal has shrunk and around the
bottom corners of the glass has come loose. I just can't afford to get it
fixed yet. Really irritating, and embarrassing, too... had this girl I
like with me, going down my [bumpy dirt] road, and this metal-glass
clacking noise kept coming from the back. She asked what it was, I just
said my car was falling apart. Thankfully, she has a sense of humour. Of
course, I told her what it was (the hatch glass popping out and back into
'socket'), and now she just thinks I need a new car. Well, at least she
doesn't mind riding in it like one girl I used to date...

Anyhoo, thanks for the info.
