What type of vehicle? Disconnect the connector for the ac clutch coil. Connect a test light to ground, and the other to the connector (connector has 2 wires). With the engine on and ac on, one of the wires should have power and light the test light. Then connect the test light to battery positive and probe the other wire to verify a ground is present, if so, the test light will light up. If the there is no power to the coil, check the ac fuse and relay. If there is power there, you are either low on refrigerant or the compressor clutch coil has an open. There may be a few other things to check, but we will need to know what type of vehicle you have.
