You guys sound like recirculation is a secure way of killing yourself in
a Vanagon :-)
I doubt any Vanagon is airtight enough to keep all fresh outside air
out...even with that recirc mod.
The rear windows exhaust vents on 87+ Vanagons basically replace every
other cars exhaust vents in the trunk.
The earlier door vents for me create a terrible draft on the hips, so I
would have had them always closed (don´t own one of these). I think
their main purpose is venting the vhicle while slamming the doors shut,
just like the rear window vents or the standard car´s trunk vent.
I know the current cars recirc flaps, but don´t know if they, for
security reasons, always leave a small gap open on the fresh air side.

This is a left over from the original busses where cost was the ultimate concern. Going back to the 70's GM was probably the leader in integrated climate control with "Bi-Level", run the AC to de-fog the windows, and guaranteed outside, flow through air even if the system was set to "max" or recirculate. Most modern vehicles still follow this. If you had a Rolls Royce or Audi 5000 from the 80" it was GM AC under the hood and many parts were if you knew what you needed were available from the Cadillac dealer.

> As for heat the same approach can be used. I chuckle when I see folks get in and put the fan on high speed. I hardly use the fan, mostly just for defrost or when driving in traffic or low speeds for an extended period. 31 years and 350K later my original dash fan is still working. If you look at the pictogram near the fan knob and wedges at the levers there are hints how to get the best results. Full defrost or defog all levers to the right and fan speed "2". After defog and traveling at speed I close the defrost flap and move the footwell lever to that notch ~1.5 inch to the right. This gives a controlled air flow allowing time for the heater core to really heat the air. Add the rear heater and the interior gets toast warm. If it doesn’t something is wrong. IF you don’t remember when the front heater core was last changed most likely it needs to be done. They clog or fail internally and they also clog with road dirt on the outside reducing there effectiveness. For 87 and earlier most Vanagons have the exhaust vents in the front doors. I always leave them open. For 88 and later most have the exhaust vents behind the rear side windows with no option to close them. Most cars exhaust the cabin through vents in the trunk.

Seems like a good way to get around the ol' no a/c on my face problem, and also the leaky air box problem. Problem I can see is the air seems to be drawn from under the dash. Tight area. On the other hand, good area to pull a/c air from/into. Thoughts anyone??
