2018 F-150 XLT 3.3L AC stopped working, compressor wouldn’t engage. Everyone says check refrigerant, pressure sensor, relay, or compressor — but check fuse #36 ‘Vehicle Power 3’ first. Mine was partially disconnected because of aftermarket wiring for headlights/running boards. Reseated it and AC worked immediately. Also check if fuse #36 is blown.”

Walahhhhhhh
