B2956 Ford Code - Blend Door Close Circuit Failure Or Short
Quick Answer
Under normal operation, to rotate the mode door actuator clockwise, the Electric Manual Temperature Control (EMTC) Module or Electronic Automatic Temperature Control (EATC) Module supplies voltage to the Blend, Floor/Defrost and Panel mode door actuator motors through the door actuator feed B circuits, and supplies ground through the door actuator feed A circuits. Common causes include Faulty Blend Door Actuator Motor, Blend Door Actuator Motor harness is open or shorted, Blend Door Actuator Motor 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.

Code B2956 Ford Description
The mode door actuator feedback resistors are supplied a ground from the EMTC module or EATC module by the mode door actuator return circuits and a 5-volt reference voltage on the mode door actuator reference circuits. The EMTC module or EATC module reads the voltage on the mode door actuator feedback circuits to determine the mode door actuator position by the position of the actuator feedback resistor wiper arm.
