Some customers may complain the HVAC system not maintaining the correct temperature or the ambient (outside) temperature reading incorrectly. This is caused by a failure in the ambient temperature sensor. To correct this issue, the ambient temperature sensor has been modified. |

Some vehicles may exhibit insufficient A/C performance / insufficient airflow from vents or ducts. These concerns may be caused by an evaporator temperature sensor malfunction due to insufficient water-proofing. This may result in a detection error and therefore, improper operation of the A/C system. To eliminate this concern, the production process of the evaporator temperature sensor has been modified to ensure proper water-proofing. |
