We need to start with checking pressures. If your system is low then the compressor will not come on. You need a gauge set that will test high and low side pressure. Let me know what they are and we can go from there.

It appears your vehicle doesn't have a traditional AC relay. It calls it a MG/CLT relay. If you can locate this relay in the engine compartment fuse box (right side of the engine) we can check that as well.

I attached the info about this and the process to test it. If this is the one that was empty then we need to put a relay in and retest the system.
