Well, I did it finally!

I found on "Joel Walker's Own Page" reference to flipping the fresh air
outlets in the dash of his Vanagon.  By default, the outlets require the
driver or passenger to flip the knob thingy down for fresh air.  So I
thought I'd give it a try since I agree with his "preconceived notions of
how-a-car-should-be built...".

Last night, it took me 30 minutes to do both outlets of the Vanagon.  I had
to remove and disconnect the driver console and remove the glove compartment
to access the four tabs which hold in place the outlets.  After pushing the
tabs down and carefully pushing the outlets out, I flipped them the other
direction, pushed them back into the vent tubing and popped them back into
place.

So now the driver side and passenger outlets are set so if fresh air is
wanted, flip the knob thingy UP (just like turning on a light).
