B226D Lincoln Code - Right Blend Door Motor Stalled
Quick Answer
Under normal operation, to rotate the blend door actuator, the Electronic Manual Temperature Control (EMTC) or Electronic Automatic Temperature Control (EATC) module supplies voltage to the actuator motors through the door actuator clockwise circuits, and supplies ground through the door actuator counterclockwise circuits. Common causes include Faulty Right Blend Door Actuator, Right Blend Door Actuator harness is open or shorted, Right Blend Door Actuator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
