Good evening,
Does the compressor engage when you command A/C?

Do you have a set of gauges to test the high and low side of the system? If not, you can rent a set at a parts store.

I attached a wiring diagram for you to view of the compressor. If you have a test light and volt meter, we can do some testing.

Check the fuses listed in the fuse block. Check them for power on both sides.
