I have a 97 vortec 350 in my 72. I used every thing for the a/c from the 97 except the condensor. I have put 32 oz of 134a & it still doesnt cool. I hooked up the pressure switch on the accumilator. There is a switch on the high pressure side of the manifold that goes on the compressor & a switch on the back of the compressor. Do these need to be hooked up for it to work properly?
