Jumping in ahead here, as there's quite a bit of unread thread left...

Mark has has a very slight brain fart.  The blower drives the dash
vents; however some may-he-be-cursed-forever prior to '89 changed
things so that those vents are temperature controlled instead of
straight from the outside. Reduced the volume some as well, p'raps my
heater core is clogged with dust.

Regardless, to get a good blast through those dash vents, everything
else has to be shut off, which means left for the defrost lever and
right for the floor air and rear air levers.  Curiously enough, by
the way, those levers all work exactly the way it says they do in the
user's manual for the van.  Folks who think otherwise should read
slower.  Not only that, they work the way the face-plate symbology shows.

VW apparently envisaged a situation where a blinding ice storm came
from nowhere and required the driver to achieve sudden maximum
defrost with one wild rightward sweep of his arm...to pay for that
they went against decades or centuries of tradition that Right is
More for control levers.  The poor manual writers did the best they
could with the situation.
