Four Seasons 73378 blend door actuator for the 2006-2010 Kia Optima and other vehicles is the motorized unit that moves an air door in the HVAC system when you change the temperature or vent setting.
- Engineered and tested for years of trouble-free operation, backed by over 50 years of mobile A/C experience.
- Meets or exceeds OE specifications for fit and function.
- Has a quality internal motor, drive gears, electronics and connections.
- Tested for function, durability and longevity.
A worn HVAC blend door actuator can show up as clicking behind the dash, air that stays hot or cold whatever the setting, or air coming out of the wrong vents. Those signs can have other causes, so look over the actuator's connector and wiring for damage with the engine off before you replace it.
The 2010 Kia Soul and the 2011-2016 Hyundai Equus also fit, and the range goes further. If your car isn't named here, look up its year, model and engine in the "Vehicles it fits" section.
