Thanks Jerry--the dashboard vents close nicely, it's just the other stuff
that leaks when it's supposed to be shut off.  The only thing that concerns
me is this summer when I (hopefully) have the AC working again, it might be
nice to shut off most of the outside air.  Right now, it just pours in
through the floor and defrost vents.
