11. Turn the ignition switch OFF.
12. Measure the resistance between the No.14 and No.15 terminals of the audio-HVAC display panel connector A (22P).
Is the resistance less than 24 kOhms?
YES - Check for loose wires or poor connections at audio-HVAC display panel connector A (22P) and at the A/C pressure switch 2P connector. If
the connections are good, substitute a known-good audio-HVAC display panel, and recheck. If the symptom/indication goes away, replace the
original audio-HVAC display panel.
