a/c compressor not engaging

I checked the fuses and swithed the horn relay with the a/c compressor relay (same partl). The horn still works and the compressor still doesn't.
Anybody know what to check next? Thanks

put pressure gauges on and make sure you have enough gas to allow compress to run. gas to low will not run. its a safety. most lilky need to be above 25 PSI static.

There is a low cut off switch in the system. If you have a voltmeter, unhook the plug to the clutch with the a/c turned on, if you have 12 volts, go from there.
