Most Reported On
B0229 is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Body Code (GM: Air Recirculation Door Position Feedback Circuit Actuator Range/Performance).” B0229 is a body code most common on GM vehicles, indicating a range/performance fault with the HVAC air-recirculation door actuator's position-feedback circuit. The climate-control module commands the recirculation door (fresh air vs. recirculated cabin air) and reads its feedback position; this code sets when the actual position doesn't match the command or is out of range. Symptoms are usually limited to the system being stuck in fresh or recirculate mode, with possible clicking behind the dash. It is a comfort-system issue, not a safety concern, and the exact definition should be confirmed against the specific vehicle. This code is most commonly reported on 2000-2013 Chevrolet Silverado 1500, 2000-2013 GMC Sierra 1500, and 2000-2006 GMC Yukon XL, plus 1 other vehicle, with repair costs ranging from $100 to $900.
