TL AWD V6-3.7L (2010)
Is there a clicking noise from the A/C compressor clutch?
YES -
Update the ECM/PCM if it does not have the latest software See: Testing and Inspection/Programming and Relearning/ECM/PCM Update, or substitute
a known-good ECM/PCM See: Testing and Inspection/Initial Inspection and Diagnostic Overview, then recheck. If the symptom/indication goes away
and the ECM/PCM was updated, troubleshooting is complete. If the symptom/indication goes away and the ECM/PCM was substituted, replace the
original ECM/PCM See: Engine Control Module/Service and Repair.
NO -
Check for poor connections or loose terminals at the A/C clutch relay and the ECM/PCM. If the connections are OK, check the A/C clutch relay See:
Power and Ground Distribution/Testing and Inspection. If needed, repair open in the wire between the ECM/PCM (A13) and the A/C clutch relay, and
check the other A/C system parts.
