A/C Clutch won't engage

[trainguy1989]

As the title states my A/C Clutch won't engage. It is not seized as I can turn it with my hand. I smacked it with a pole nothing. Checked for Freon and the system is full. Jumped the clutch cycle switch and nothing. Fan comes on and the engine starts to idle higher anticipating compressor engagement. But it does nothing. It worked before I parked it for the winter. I pulled the connector off the clutch and I have no voltage there whatsoever. What could be causing this? CCRM?

Jumper from clutch connector to battery +12V and see if it engages; rules out clutch as possible problem.

one of my cars (the 93 Sable SHO) has a bad wire between the ccrm and the compressor clutch, so I had to run a set of "jumper wires" between there to make the compressor work.

you can check this by putting a test light or voltmeter on the 2 wires at the ccrm. (which 2 wires depends on your ccrm code). if there is voltage at the ccrm but not at the compressor, you have the same type of wiring issue I have.
