OK, the early Vanagons do indeed have this feature as my '81 has the four
levers with the lowest one sending air into the rear of the cabin, out the
vents over the sliding door.  The passage is there on the driver's side
too, but is covered with a block-off plate before it even gets to the
driver's door.  Obviously on a Westy, there are no upper vents on the
driver's side in the rear cabin.

The passenger Vanagons do indeed have upper vents in the rear cabin on both
sides and so the passages through the doors are functional on both sides.

As far as the vent at the rear of the door with the blue lever, that is not
connected to the vents for the rear.  Those doohickeys are supposedly for
"fresh air circulation."  Our vans are supposed to be airtight.  VW was
known for that.  So theoretically, if you want any fresh air coming into
the van, you need to provide an outlet so you get a flow-through kinda
thing going.  That's what those flaps do.  You open them and you supposedly
get better ventilation as the air coming in doesn't have to "work as hard"
to get in.

That's the theory behind them anyway.  Note that the air-cooled Buses also
had those vents in the doors.
