How do I fix Chevrolet Impala 2006, 3.5L engine, that is getting the error code B0238?
@jeffwashington , Jeff, Are you experiencing any problems as far as heat/defrost blower vent direction if not, record code for future reference and erase. If you are having a problem, one of the mode actuators could be sticking/faulty, the dealer would have to hook up their Advanced scanner to locate and diagnose precise fault, bad wire/plug, control module, faulty/sticking actuator. DTC B0238 Air flow control #1 (defrost) circuit malfunction DTC B0238 Mode Door Circuit Range the door air-mix actuator Below are a few links to read through, sounds like these actuators fail often, last link tells of a reset procedure you may want to try. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. http://www.gmforum.com/2000-2005-90/hvac… http://chevroletforum.com/forum/impala-1… https://www.2carpros.com/questions/2006-…
