B297E Lincoln Code - Passenger Blend Door Actuator Drive Circuit Open
Quick Answer
Under normal operation, to rotate the blend door actuator clockwise, the Electronic Manual Temperature Control (EMTC) Module or Electronic Automatic Temperature Control (EATC) Module supplies voltage to the blend door actuator motors through the door actuator feed A circuits and supplies ground through the door actuator feed B circuits. Common causes include Stuck or damaged linkage or door, Faulty Blend Door Actuator, Blend Door Actuator harness is open or shorted. 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.
