B2916 Mercury Code - Auxiliary Blend Door Motor Circuits Shorted
Quick Answer
Under normal operation, to rotate the auxiliary temperature blend door actuator clockwise, the Smart Junction Box (SJB) supplies voltage to the auxiliary temperature blend door actuator motors through the circuit and supplies ground through the circuit. Common causes include Faulty Auxiliary Temperature Blend Door Actuator, Auxiliary Temperature Blend Door Actuator harness is open or shorted, Auxiliary Temperature 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.
