All modern compressors utilize a clutch and drive pulley. The caster is driven off a drive belt whenever the engine is running. When the A/C button is pushed the clutch is engaged, locking the compressor to the pulley, causing it to plough.

If the compressor has failed, the A/C system will not work. A compressor that is seized may also contaminate the rest of the A/C system with metal debris.
