You need to check the pressostat switch. It is on the coolant line close to the firewall. With the engine on and AC set to engage, unplug the wires and short them with a paper clip. If the compressor starts, then you need a new switch.

If the compressor fails to engage, check the clutch gap. A simple light push on the center of the clutch with a broom stick should get the clutch to engage if the gap is too large.
