I have seen the following types of AC units on Vanagons;
#1) Behind the dash, After market BEHR. Move the radio.
#2) Westy hang over the rear bed, After market Dealer install. The Box.
#3) Vanagon over the drivers head with ductwork to distribution above the
visors, VW dealer install. Falls down on your head.
#4) Vanagon, later models (saw on 87 model), all the way in the rear with
ductwork going forward overhead. Ductwork falls often.
Once you've removed a Vanagon Dash and replaced the heater / fresh air
distribution box you'll fully understand why so few vehicles have behind
the dash A/C units. This is grueling 10 hour job with a few unique
catches in the process, grind off special nuts, push seals and cause air
leaks etc.
"Larry Chase" lchase@attglobal.net Has pictures of a recent unit he
installed in a syncro. Collect his pictures for your files they may be of
later assistance.
Although that air distribution box looks huge, it is honeycombed with
working parts and internal ductwork. Pictures are not adequate, get one
(remove it yourself as a training procedure) open it up and investigate
for yourself.
Since I have an Air Cooled air distribution center already on the floor
I'll be glad to supply pictures of what I can at various disassembly
levels if you need them. As for the Wasserboxer box, it's very little
different, just the heater coil in the bottom and most everything else is
the same.
