Testing Air Conditioner Clutch

Testing Air Conditioner Clutch
I went to give my a/c a workout yesterday and found out that it hasn't survived through the winter. Both settings on the dash did not engage the clutch on the a/c compressor, and the fuse for a/c & cruise was good. I swapped a relay for the air con and fuel pump but that did not make a difference either.
How can I test the clutch to see if it is functional?
Are they a bear to replace?

You can jump the relay connections. You may be out of refrigerant. When refrigerant is low, the car will prevent the clutch from engaging unless you jump the relay. Its in the fusebox under the hood on the right side.

I wasn't able to get leads on the compressor itself so I cut the wires going to the compressor up by the egr valve and tested from there with a spare battery. The clutch engaged just fine, so I was low on R134a. Added in a 10oz can and the compressor kicked on but unfortunately still no cold air, must have a larger problem.
