Is there a clicking noise from the A/C compressor clutch?
YES
The A/C MG CLUTCH RLY CL- wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away and the PCM was updated, troubleshooting is complete. If the symptom/indication goes away and the PCM was substituted, replace the original PCM.
NO
Check for poor connections or loose terminals at the A/C compressor clutch relay and the PCM. If the connections and terminals are OK, check the A/C compressor clutch relay. If needed, repair an open in the A/C MG CLUTCH RLY CL- wire between the PCM (A12) and the A/C compressor clutch relay, or other parts in the A/C systems.
