Swap relay 204 with 206 in the engine bay fuse box.
See it that brings back your A/C.
If yes, replace the relay that was in the 204 position.
If no, there is likely either the pressure switch is bad or the system is low on charge.
You can jump the pressure switch to see if the compressor clutch locks up.
If yes either the switch is faulty or the system is low on charge.
Good luck.

If jumping the pressure switch does not pull up the compressor clutch then there is no power to the circuit.
The problem has to be before that point toward the WOT relay.
If that relay is not operated with the motor running then the issue is before that point back toward the selector switch and power feed.
Use a voltmeter to test for the point it becomes absent.
Is the clutch connector plugged up solid?
Is the clutch good?
For the circuit, see Haynes manual page 12-34.
Good luck.
