B226E Code - Mode 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 Mode Door Actuator, Mode Door Actuator harness is open or shorted, Mode 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.

Code B226E Description
The actuator feedback resistors are supplied a ground from the EMTC module or EATC module by the door actuator return circuits and a 5-volt reference voltage on the door actuator reference circuits. The EMTC module or EATC module reads the voltage on the blend door actuator feedback circuits to determine the door actuator position, by the position of the actuator feedback resistor wiper arm.
