The Dorman - OE Solutions HVAC Blend Door Actuator (604-992, also written 604992) is the small electric motor that drives an air door or blend door inside the HVAC case, positioning the door to direct and mix airflow through the system. If a failed actuator is behind uneven cabin temperatures, doors that won't move, or clicking/grinding from behind the dash, this unit is engineered to drop in like the original on a wide range of listed GM and Saturn vehicles. It is cataloged in both MAIN and AUXILIARY positions, so check the application notes and position before ordering.
Fitment: 2008-2012 Buick Enclave, 2005 Chevrolet Equinox, 2008-2012 Chevrolet Malibu, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, 2005-2010 Pontiac G6, 2007-2009 Saturn Aura, 2007-2010 Saturn Outlook, and 2002-2007 Saturn Vue.
