B226D Mercury 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.

Code B226D Mercury 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.
What are the Possible Causes of the DTC B226D Mercury?
- Faulty Right Blend Door Actuator
- Right Blend Door Actuator harness is open or shorted
- Right Blend Door Actuator circuit poor electrical connection
- Faulty Electronic Manual Temperature Control (EMTC) or Electronic Automatic Temperature Control (EATC)

The common symptoms include inconsistent or incorrect temperature control from the HVAC system, such as hot air blowing when cold air is selected or vice versa.
2. What can cause the Right Blend Door Motor to stall in a Mercury, triggering code B226D?
The stalling of the Right Blend Door Motor in a Mercury can be caused by a faulty blend door actuator, a jammed blend door, wiring issues, or a damaged HVAC control module.
3. How can I diagnose the issue triggering OBDII code B226D in my Mercury?
To diagnose the issue, you can start by checking the blend door actuator for proper operation, inspecting the blend door for any obstructions, and using a scan tool to analyze the HVAC system for any error codes.
4. Is it possible to reset OBDII code B226D in a Mercury without repairing the issue?
While clearing the code may temporarily turn off the check engine light, it is not recommended to reset the code without addressing the underlying problem, as it will likely reoccur.
5. Are there any DIY repair tips for resolving OBDII code B226D in a Mercury?
DIY repair tips may include checking and replacing the blend door actuator, ensuring the blend door moves freely, inspecting and repairing any damaged wiring, and resetting the HVAC system after repairs are made.
6. Can a faulty temperature sensor trigger OBDII code B226D in a Mercury?
While a faulty temperature sensor may indirectly affect the HVAC system, it is not a common cause of the Right Blend Door Motor stalling and triggering code B226D.
7. How critical is it to address OBDII code B226D in a Mercury promptly?
It is important to address code B226D promptly, as ignoring HVAC system issues can lead to discomfort while driving, reduced visibility due to improper defrosting, and potential damage to other HVAC components.
8. Is it safe to continue driving a Mercury with OBDII code B226D unresolved?
While it may be safe to drive the vehicle with the code present, it is not recommended due to the potential impact on comfort and visibility. It is best to address the issue as soon as possible.
9. Can extreme weather conditions contribute to triggering OBDII code B226D in a Mercury?
Extreme weather conditions, such as extreme heat or cold, can exacerbate HVAC system issues and potentially contribute to triggering code B226D if the blend door motor is already experiencing problems.
10. How much can I expect to pay for professional repairs related to OBDII code B226D in a Mercury?
The cost of professional repairs for code B226D can vary depending on the exact cause of the issue, but it may range from $200 to $500 or more, including parts and labor.
