----------------- 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.
