Need help with AC

Have a 83 cougar LS. 5.0. Turn on the Air nothing. Jumped the low pressure switch pops fuse #6. Pulled wire for clutch. Still pops #6. Put it all back charged the system got to pressure pops #6. Talk to 4 garages all 4 refused to work on it. What I need to know if there is a relay. What’s its location? Where is this diode. This is a 65000 mile un touched car.

There is a WOT cutoff relay that disconnects the compressor clutch at wide throttle openings. Sometimes the wiring connecting to the relay will have the insulation degrade and fall off, causing the wires to touch and short. You can check that first and see if it is causing a issue.
