1. Disconnect the mode control motor 7P (4-door) or 10P (2-door) connector.
2. Disconnect audio-HVAC display panel 22P connector.




3. Check for continuity between body ground and audio-HVAC display panel 22P connector terminals No.2, 3, 4, 5, 9, 11, and 12 individually.

Is there continuity?

YES - Repair any short to body ground in the wire(s) between the audio-HVAC display panel and the mode control motor.

NO - Go to step 4.




4. Turn the ignition switch ON (II), and check the same terminals for voltage.

Is there any voltage?

YES - Repair any short to power in the wire(s) between the audio-HVAC display panel and the mode control motor. This short may also damage the audio-HVAC display panel. Repair the short to power before replacing the audio-HVAC display panel.

NO - Go to step 5.







5. Turn the ignition switch OFF, and check for continuity between the following terminals of audio-HVAC display panel 22P connector and the mode control motor 7P (4-door) or 10P (2-door) connector.

Is there continuity?

YES - Check for loose wires or poor connections at audio-HVAC display panel 22P connector and at the mode control motor 7P (4-door) or 10P (2-door) connector. If the connections are good, test the mode control motor. If the mode control motor is OK, substitute a known-good audio-HVAC display panel, and recheck. If the symptom/indication goes away, replace the original audio-HVAC display panel.

NO - Repair any open in the wire(s) between the audio-HVAC display panel and the mode control motor.
