On this system you also have a a/c relay, the high and low pressure switches, and the a/c electronic clutch.
The first thing would be to check the relay, you can switch then out by using other relays of the same type that are located in the relay service center.
Check for power at the compressor clutch. Check the charge pressure of the system, if low on refrigerant the system will not operate, you could of developed a leak in the system and lost pressure. Check for power and continuity at the pressure switches.
