A/C compressor will not turn on

[mjmike]

Have a 2011 6 cyl same problem - pressures seem okay. Compressor sometimes will come on and work for a few minutes, but more often than not not at all. I found a 3 pin "system" switch, but unable to find a low or high pressure switch. How would I go about ruling out the CCRM?? Basically need advice on how to troubleshoot.....thx
