A/C Clutch Relay Output

NOTE: For circuit identification and wiring diagram, see WIRING DIAGRAMS article. If Powertrain Control Module (PCM) is replaced, PCM must be reprogrammed. See PROGRAMMING  . After each repair procedure has been completed, reconnect all components. Perform POWERTRAIN VERIFICATION TEST VER-2  under VERIFICATION TESTS to ensure system is functioning properly.
  1. Turn ignition on. Using scan tool, actuate A/C clutch relay. A/C clutch relay is located in Power Distribution Center (PDC). See Figure . PDC is located in engine compartment. See Figure . If A/C clutch relay is not actuating, go to next step. If A/C clutch relay is actuating, A/C clutch relay output circuit is operating properly at this time. Test is complete.
  2. Turn ignition off. Disconnect A/C compressor clutch harness connector. Measure resistance between ground and Black wire at A/C compressor clutch harness connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in ground circuit.
  3. Turn ignition on. Using scan tool, actuate A/C clutch relay. Measure voltage between ground and A/C clutch relay output circuit (Dark Blue/Black wire) at A/C compressor clutch harness connector. If voltage is 11 volts or less, go to next step. If voltage is more than 11 volts, replace A/C compressor clutch.
  4. Turn ignition off. Remove A/C clutch relay from PDC. Connect a test light between ground and fused battery voltage circuit (Red/Light Green wire) at A/C clutch relay harness connector terminal No. 30 in PDC. See Figure and Figure . If test light illuminates brightly, go to next step. If test light does not illuminate brightly, repair open or short in fused battery voltage circuit.
  5. Measure resistance of A/C clutch relay output circuit (Dark Blue/Black wire) between A/C compressor clutch harness connector and A/C clutch relay harness connector terminal No. 31 in PDC. If resistance is less than 5 ohms, replace A/C clutch relay. If resistance is 5 ohms or more, repair open in A/C clutch relay output circuit.
