-----------------
There are no high / low switches on some models.  Like no switches , none.
My 86 westy 2wd 4 speed had none and  there were several others out  there
that checked and found  none. I think all were westys.    My  a/c mechanic
noticed this   when my high side went over 450  psi.  He  got a bit excited
and he is usually an ultra calm person.  He and   I have sense added
switches to my westy,  thanks  to Bill Dummitt.  You can sense  the  high
pressure building up,  the compressor starts complaining  by vibrating the
whole van.
