The A-Premium HVAC heater blend door actuator (replaces 8710607120) is a direct-fit replacement part that restores HVAC airflow direction and temperature blend control for compatible Lexus and Toyota models.

If the dashboard vents in your vehicle are not switching between hot and cold or the airflow direction isn’t responding, a worn blend door actuator can be the cause. This A-Premium unit is designed to match OEM fit and function for specified Lexus ES350 and RX350 models and a range of Toyota vehicles, including Avalon, Camry, Highlander, Venza and Sienna. It arrives factory-tested and backed by a one-year unlimited-mileage warranty so you can replace a failed actuator with confidence.

How do I know this actuator fits my vehicle?

Confirming fitment before purchase prevents installation frustration. This actuator replaces reference numbers 604-906, 604906 and 87106-07120 and fits specific model years and assembly origins listed below.

• Compatible models: Lexus ES350 (2016–2018) and RX350 (2010–2015, Built in USA)
• Toyota models: Avalon (2005–2018), Venza (2009–2016), Camry (2007–2011 built in USA; 2012–2017 with automatic A/C)

What should I expect during installation?

Installation complexity varies by vehicle but typically involves removing lower dash panels or glovebox access to reach the HVAC housing. Basic hand tools are usually sufficient; however, some models require dashboard trim removal or lifting the glove compartment for clear access.

• Tip: verify the actuator’s mounting orientation against the old unit before tightening
