To test the AC compressor on a 1993 Ford Ranger with a 4.0 V6 engine, start by checking the refrigerant levels to ensure they are adequate. Next, with the engine running and the AC set to maximum, observe the compressor clutch; it should engage when the AC is activated. If the clutch does not engage, use a multimeter to check for voltage at the clutch connector. If there is voltage and the clutch still does not engage, the compressor may be faulty and require replacement.
