Code B295C Description

The B295C diagnostic trouble code (DTC) indicates that there is an issue with the right blend door potentiometer feedback circuit in the vehicle's HVAC (Heating, Ventilation, and Air Conditioning) system. The blend door potentiometer is a sensor that helps regulate the temperature inside the vehicle by controlling the blend door, which directs the flow of heated or cooled air. When the feedback circuit is open, it means that there is a break or interruption in the electrical connection between the potentiometer and the vehicle's control module.
