My r4 compressor doesnt have a cycling switch in the back of it or wires to hook one in either. it has a new one in the accumulator and it is hooked up but it still dont cycle. shouldnt there be one in th compressor and if so how does it need to be wired in? thanks for the help.
That's a high pressure cut-off switch in rear of compressor- and no, some models of C/K trucks did not use them-thus, no wire harness to plug them in..- cycling is only necessary to avert freeze-up--if it is really hot- no cycling will occur.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
