Have power at low pressure switch. (Attached to evaporator. Correct?). Jumpered it, no clutch engagement. Refrigerant pressure good.I have read about fuses, replays, and ccrm. Visually inspected all fuses I know about, nothing apparently bad, but I don't know about relays (which) or how to test.1) where is high pressure switch, and how to test? 2) how to test ccrm, if that is the next step thanks!

Start with basics. What are the exact pressures?

The low switch is on the dryer, that is one of the signals that turns on the compressor. The high side turns off the compressor in the event of too high pressure.
