Hi =
Karl,
You are
not the only one with no switches. My 86 westy had no high or low =
switches
either. There were some other listees with 86 westys that had no
switches. I ended up installing switches on mine. I =
use the
high switch to energize the fan stage 3 relay. This rarely =
turns on
but if the pressure gets up there while stopped for a while it sometimes =
engages. I have also found that the 86 westy had a smaller =
condenser and
evaporator than what was on an 86 van. I have installed most of the ac
components from an 86 van on my 86 westy thanks to Bill Dummitt. I also
converted from r12 to r134a and am very happy with the unit so far. I =
now turn
the ac temperature up most of the time other wise it gets too cold, =
never had
this problem before. I am thinking that r134a has had a lot of =
unjustified
bad press. My pressures are just like Michael Modl posted a few =
weeks ago
, thanks for all the expert information Michael. I never thought it =
possible
for 40 degree air to exit my evaporator but it goes down there =
pretty
quickly now. Another note there is now some compressor oil =
lubricant
available that can be used on any freon charge.

Thanks to all those who sent =
thier advice on
my a/c system. Turns out that 84/85's have completely =
different wiring
of the a/c systems than the later models. After studying the =
electral
diagram for a couple hours, I finally decided to cut the red wire =
w/blue
lead and eliminate the useless "compressor cut-out relay. =
I will
later install a commercial hi-lo pressure switch and connect the lo =
side to
the compressor cut-out relay (the hi side will be wired in series =
the the lo
cutout). This will prevent compressor from sucking air in case =
of a
leak and also prevent the discharge line from blowing (like in our
tremendously hot summers). I also converted the system to =
R134a.
Runs like a champ.
Does this sound like I'm on the =
right
track?
Hey tomorrow's Friday, ain't
it!!!!!
