Ok, so just catching up with the mails.  The thread on "Heater knee bar
cross beam" has some insights.

But this vent on the bottom corner of the door is not part of the channel
that directs air through the door into the door jamb.  Somewhat odd, this
vent is simply for the interior of the door.  I can't see how air would flow
in our out of this vent.  Even the door holding strap (what keeps it from
opening too much) has a hole that might allow air flow, but there is foam
blocking the opening when the door is closed.  Apparently that leaves only
the window seals to let air flow through.

Looks like it wasn't a previous owner, but this tape (black cloth) was
installed by factory.  Maybe I better cover it over again.  Looks like it
wouldn't increase air flow.
