Dales Super Store - A/C Blend Doors

These blend doors are typically located within the HVAC (Heating, Ventilation, and Air Conditioning) system and are responsible for controlling the mixture of hot and cold air that enters the cabin. The doors can be adjusted to direct air over the heater core (for hot air) or the evaporator (for cold air) and can be positioned at varying angles to achieve the desired cabin temperature.

When you adjust the temperature settings on your vehicle's climate control system, whether you want hot, cold, or a blend of both, the blend doors are responsible for directing the air accordingly. This process ensures that the air blown into the cabin matches your selected temperature preference.

Blend doors are typically operated by electric or vacuum-controlled actuators, and their position is regulated by the climate control system based on the input from the temperature controls. Problems with blend doors can result in issues like inconsistent or incorrect temperature control inside the vehicle's cabin. If a blend door malfunctions, it can lead to discomfort and the need for repairs or replacements to restore proper climate control.
