Seems the air mix doors are not functioning correctly. Perform trouble codes retrieval to see if any are present.
1. While pressing and holding AUTO button and recirculated/fresh air button, turn ignition on. Indicators will flash on and off at one-second intervals, 4 times in succession, and a tone will sound as an indicator check. Press OFF button to cancel indicator check.
2. After indicator check is complete, system will enter self-diagnostic mode. Stored trouble codes will appear in sequence on driver's side temperature display.
3. Press driver's side temperature switch to display codes one at a time. If tone sounds when code is displayed, problem causing code currently exists. If tone does not sound when code is displayed, associated problem is past history, and does not currently exist. Press OFF button to exit self-diagnostics.
