The compressor will "cycle" more when freon is low. When the froen level drops below a certain pressure point, I do not know off hand what that is, the compressor wil stop kicking in.
Use a volt meter and check for 12v at the compressor connections. Do this with the engine off. Put the ignition switch in position 3, and turn on the A/C. If you are getting 12 volts, and the clutch is not engaging, could be a bad clutch.
