DTC 3: A Problem in the Air Mix Control Linkage, Door, or Motor

1. Test the air mix control motor.

Is the air mix control motor OK?

YES - Substitute a known-good audio-HVAC display panel, and recheck. If the symptom/indication goes away, replace the original audio HVAC display panel.

NO - Replace the air mix control motor, or repair the linkage and doors.
