Code B1264 Chevrolet Description

The B1264 diagnostic trouble code (DTC) is specific to Chevrolet vehicles and indicates a failure in the floor door actuator, which is an essential component of the vehicle's heating, ventilation, and air conditioning (HVAC) system. The floor door actuator is responsible for controlling the airflow direction within the cabin, specifically directing air to the floor vents. When this actuator fails, it can lead to improper air distribution, affecting passenger comfort and the overall effectiveness of the HVAC system.
