Fuses are good, Freon is good, pressure switch is good. Any thoughts on what is the problem?

If these are okay, we need to go to the compressor and check for power at the clutch to see if you have it when the A/C is on. If you do then the compressor has failed. If not then we have a wiring or control issue.

At that point we need to go to the relay and test the relay. Here is a guide that will help with that:
