you will need a multimeter to do this. check the a/c fuse. if its good check for voltage to the compressor clutch. there should be a connector at the compressor where you can check for this. if there is voltage then your compressor clutch is bad. if there isnt voltage then you need to check the a/c relay. jump terminals 30 and 87 of the relay socket with a fused jumper wire. if terminal 30 has voltage then you should see the compressor clutch engage varifying that your a/c relay is bad. if the compressor clutch doesnt engage then you have a wiring problem from the fuse to terminal 30 of the a/c relay since you have no power at terminal 30 of the relay. if you have no idea what i just wrote then you need to bring it to a shop.
