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?
