Subject: Air Deflector
Everything you wanted to know about Air Deflectors. Well, at least
everything that I know about them. The following applies to the '80
and '81 Vanagons. Applicability to later Vanagons is unknown.
Perhaps some OTHER demented soul would continue the quest for the
questionable value knowledge contained.
The Air Deflector re-directs the air exiting from the hot air duct to
the feet of the driver and passenger. It is attached to the plastic
air duct with a pair of tabs that fit into slots near the top outer
edges.
To remove an Air Deflector, gently pull the outer top portion to the
outside of the bus, and then gently towards the rear. This can be
done on both sides at the same time, or independently. The tab has a
slight "L" on the end to catch into the slot. Pulling on the
Deflector without un-catching the tab results in breaking off the tab.
BTDT, thus this post. Mine were wired in place for years.
Tom Young procurred an AD from a '81 for me to install (thanks) & I
proceeded to attempt to install it. Wouldn't fit. The tab design
had changed, adding ribs to stiffen and strengthen the tab. I have
another '80 Westi in my yard, and with thoughts of fixing it up
vanishing, I pulled the Air Deflector from it. Flat tabs, but it had
3 openings instead of 2. Whatsgoingonhere I asked myself.
The openings refer to the number of slots for the air to exit on each
side of the Air Deflector.
All three had the same part number- 251 259 135A
All three had different production dates, and all three were slightly
different. Here is my speculation and info for all of the future
restorers of early Vanagons. Dates were found on the Air Deflector.
9/79 has flat tabs and 2 openings
12/79 has flat tabs and 3 openings
11/80 has ribbed tabs and 2 openings
It looks like VW started with 2 openings, and later decided to go to
3 and then back to 2 openings. The AD with 3 openings had one of the
openings stuffed with a piece of foam.
I think that the ribbed tabs were added for the 1981 model, when they
changed the venting stuff to add a fan into the housing ('80 had no
fan). I guess that the 3 openings placed the air in the wrong
location. One of these cold days, I'll check out the hot air coming
from the opening and try & figure it out.
