B2267 Code - Right Side Blend Door Circuit Failure
Quick Answer
Under normal operation, to rotate the temperature blend door actuator, the HVAC module supplies voltage and ground to the temperature blend door actuators through the door actuator motor circuits. Common causes include Faulty Right Side Blend Door Actuator, Right Side Blend Door Actuator harness is open or shorted, Right Side 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 B2267 Description
The temperature blend door actuator feedback resistors are supplied a ground from the HVAC module by the temperature blend door actuator return circuits and a 5-volt reference voltage on the temperature blend door actuator reference circuits. The HVAC module reads the voltage on the temperature blend door actuator feedback circuits to determine the temperature blend door actuator position by the position of the actuator feedback resistor wiper arm.
During an actuator calibration cycle, the HVAC module drives the temperature blend door until the door reaches both internal stops in the HVAC case. If the temperature blend door is temporarily obstructed or binding during a calibration cycle, the HVAC module may interpret this as the actual end of travel for the door. When this condition occurs and the HVAC module commands the actuator to its end of travel, the airflow may not be from the expected outlets.
The Diagnostic Trouble Code (DTC) sets when the module senses no change in actuator feedback voltage when the actuator motor has been energized.
What are the Possible Causes of the DTC B2267?
- Faulty Right Side Blend Door Actuator
- Right Side Blend Door Actuator harness is open or shorted
- Right Side Blend Door Actuator circuit poor electrical connection
- Faulty Heating, Ventilation, and Air-Conditioning (HVAC) Module
- Faulty Electronic Manual Temperature Control (EMTC)
How to Fix the DTC B2267?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the B2267 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

B2267 indicates a failure in the right side blend door circuit, which controls the air temperature distribution on the passenger side of the vehicle.
2. What are the common symptoms of code B2267?
Symptoms include inconsistent or incorrect cabin temperature on the passenger side, inability to adjust temperature, and possible clicking noises from the HVAC system.
3. What causes the B2267 code to appear?
Common causes include a faulty blend door actuator, wiring issues such as broken or corroded connections, or a malfunctioning HVAC control module.
4. Can I still drive with the B2267 code?
Yes, you can drive with this code, but the passenger side temperature may not function properly, resulting in discomfort or inconvenience.
5. How can I diagnose the B2267 code?
Diagnosis typically involves checking the blend door actuator for proper operation, inspecting wiring and connectors for damage, and verifying signals from the HVAC control module.
6. How do I fix the B2267 code?
Repairs may involve replacing the blend door actuator, repairing damaged wiring or connectors, or reprogramming or replacing the HVAC control module.
7. What tools are needed to fix a B2267 code?
You’ll likely need a diagnostic scan tool, a multimeter for electrical testing, and basic hand tools to access and replace the blend door actuator.
8. How much does it cost to repair the B2267 code?
Costs vary but typically range from $150 to $400, depending on whether just the actuator is replaced or additional electrical repairs are needed.
9. Can I fix the B2267 code myself?
If you’re comfortable working with automotive electrical systems and have the necessary tools, you may be able to fix it yourself by replacing the actuator or repairing damaged wires.
10. What happens if I ignore the B2267 code?
Ignoring the code can lead to prolonged discomfort in the cabin due to improper temperature control and potentially further damage to the HVAC system components.
