Summary

Certain vehicles fail to comply with the requirements of CMVSS 103 - Windshield Defrosting and Defogging. The Heating, Ventilation, and Air Conditioning (HVAC) system may fail. If this occurs, the blower would not function properly and the mode selector would remain in the last known setting. If the windshield began to fog or frost, there may not be enough airflow to safely clear the windshield, resulting in reduced driver visibility, which may lead to a vehicle crash with injury or death. Correction: Dealers will reprogram the HVAC control head module.
