A/C Compressor Clutch Test

  1. Disconnect the A/C compressor clutch connector to the A/C compressor clutch.
  2. Connect positive battery voltage directly to the connector for the A/C compressor clutch.
  3. Supply a ground to the A/C compressor assembly.
  4. If the A/C compressor clutch is normal, there will be a "click." If the pulley and armature do not make contact ("no click"), there is a malfunction.
