Get your climate controls moving again with the Four Seasons HVAC Mode Door Actuator 73156, a direct-fit replacement Gmc Envoy mode door actuator that drives the MAIN mode door inside the HVAC housing. This actuator positions the mode door to direct airflow to the vents, floor, or defrost outlets on command from the climate controls. It installs as a direct-fit replacement for the listed 2003-2009 GMC Envoy, 2003-2009 Chevrolet Trailblazer, 2004-2007 Buick Rainier, 2005-2009 Saab 9-7X and more — see the Buyer's Guide tab for the full list of applications.
- Complete assembly: includes the lever arm, gear, cam gear hardware and linkage as applicable.
- Quality internals: built with an internal motor, drive gears, electronics and connections.
- Meets or exceeds OE specifications for fit and function.
- Tested for function, durability and longevity, backed by Four Seasons' decades of mobile A/C experience.
If your chevy Trailblazer mode door actuator has failed, common signs include air blowing from the wrong outlets, a mode door that won't switch between vent, floor and defrost, or a clicking/knocking noise behind the dash. If a failed MAIN mode door actuator is the cause, this unit replaces it.
