The outboard floor vents are connected to the wing root openings.

The heater vents run along the center tunnel between the seats.

The overhead vents connect to the vertical stabilizer opening with the
blower in between.

Yep, but he's not talking about ANY of those vents.

There is a fine grating piece that fits alongside the rear seats,
between the seat and the outer wall of this model of Cherokee. This
grating allows air to flow freely the cabin and the under-seat
compartment (where the battery is on some Cherokees), and then out a
hole in the bottom of the plane.

Think "flow-through ventilation", circa Pontiac 1968.

That hole has a shroud around it that makes it act like a venturi in
flight, actually SUCKING the air through those mesh grates, and out the
bottom of the plane. For some reason, the OP is getting air coming OUT
of that grating -- only on the right side -- which is seemingly
impossible.

Jay has it correct.
I happen to be a pretty capable mechanical engineer and this issue has me
totally foxed.
The airplane is in the shop right now and I have asked them to pull the rear
seat plank out again.
As soon as they do that I am going to have another look and also check why
air is not coming out of the mesh grill on the other side of the seat plank.
Thinking about it, they also fitted new seals to the other 4 floor ducts,
which also now shut off very nicely.
Perhaps she is just too tight :-)
