- Summary
- 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.
