Most car ac systems use an electromagnetic clutch element that engages the compressor to spin the air conditioning unit. The compressor clutch will usually be located under your hood on the left side near the front of your car. To check ac compressor clutch air gap, simply insert a feeler gauge between the clutch plate and pulley with the engine off.
