I started having AC issues 5 days ago.
Compressor would start but not the fan.
Fan would start but not the compressor.
Resetting shore power fixed it a few times.
Firing up the generator fixed it a few times.
Starting up the engine fixed it a few times.
Simply turning the ignition to ON but not starting the engine fixes it too.
