  1. Disconnect A/C clutch relay harness connector. A/C clutch relay is located in under-hood fuse/relay box. Using proper mini-schematic and an ohmmeter, check continuity between A/C clutch relay winding terminals. See WIRING DIAGRAMS article. Continuity should be present. Check continuity between clutch drive circuit terminals of relay. Continuity should not be present.
  2. Using jumper wires, apply ground and battery voltage to relay winding terminals. Continuity should now be present between clutch drive circuit terminals of relay. Replace A/C clutch relay if continuity is not present.
