Default 1992 Honda Civic DX A/C Clutch Not Engaging?

I have a 1992 4dr Civic DX and about a month ago the A/C quit blowing cold air, it just blew warm air. Upon tinkering around I figured out that the A/C clutch wasn't engaging. When I move the A/C switch to max, the RPM's change and the blower motor comes on, but the clutch stays disengaged. I checked with a voltmeter for power going to the relay for the clutch, and there was power going to the relay. The wires from the relay go to a little nickel sized black thing (I'm guessing the coil?) and from there they go down into the clutch, so there isn't really a spot to test for voltage past the relay. I'm not sure what to do from here. Since the wires from the black thing (coil?) disappear and go down into the clutch, do I need to pull the clutch off no matter what I do? Is replacing the coil an option? How would I know the coil is the culprit? I need guidance!Please help!

First off, either get or examine a electrical schematic for your Civic's HVAC systemYou will see that there is a low pressure switch incorporated into the system to prevent the clutch from engaging.Low pressure meaning refrigerant, which also contains oil to lubricate the compressor.If the freon pressure is low, this switch prevents the clutch from engaging, saving the compressor itself.Check system pressure first then go from there
