DTC 1: An Open in the Air Mix Control Motor Circuit

1. Disconnect the air mix control motor 7P (4-door) or 5P (2-door) connector.
2. Disconnect audio-HVAC display panel 22P connector.







3. Check for continuity between the following terminals of audio-HVAC display panel 22P connector and the air mix control motor 7P (4-door) or 5P (2-door) connector.

Is there continuity?

YES - Check for loose wires or poor connections at audio-HVAC display panel 22P connector and at the air mix control motor 7P (4-door) or 5P (2-door) connector. If the connections are good, test the air mix control motor. If the air mix 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 air mix control motor.
