The part number is F5RZ54280B62A. It's called a grille. It's not too
much
work. You need to remove the plastic piece covering the trunk lock area
and
then remove the carpet on the side of the trunk. To get the plastic
piece
off, you need a phillips screwdriver for the four plastic screws (be
gentle
with the screws). There are also two plastic pop rivet things you need
to
remove. The carpet is held in place by a plastic screw and two plastic
pop
rivets. Once you remove the carpet, you will see the black plastic vent
that
you just bought. Remove the new gasket from the new vent;
unfortunately, you
don't use the new plastic vent because you'd have to remove the bumper
to
install the whole assembly. The vent snaps into the sheet metal. Remove
the
old gasket from the old vent, clean the vent and sheet metal as best
you can
(for a good seal), and then insert the new vent seal into the old vent,
making sure that you insert the curved part of the gasket into the
curved
part of the vent. Make sure that the new gasket is firmly seated in the
vent. This takes some time to work the gasket into the vent because
there is
not a lot of room for your hand, but if you are patient, the whole
gasket
eventually will be well seated in the vent. Snap the vent back into the
body, being sure to position the bottom of the vent in the metal first.
You
shouldn't see water leaking through the vent anymore.
