11. Turn the ignition switch OFF.
12. Measure the resistance between the No.9 and No.10 terminals of the audio-HVAC display panel 22P connector.
Is the resistance less than 24 kOhms?
YES - Check for loose wires or poor connections at audio-HVAC display panel 22P connector 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.
