Hi there, thanks for writing in. On most imports and some domestic cars, there the AC blend door distributes the air to different vents when the option is selected. This component is controlled by an electric actuator. Sometimes the fuse to the actuator or the component itself is responsible for the condition you’re experiencing. If you’re buying a used vehicle, you might want to contact one of our local mechanics to complete a pre-purchase vehicle inspection.
