Detailed Description

This HVAC heater blend door actuator controls the blend door movement that directs air through the heating and air conditioning system.

Common Issues It May Solve

  • Incorrect air direction from the dash vents, floor vents, or defrost outlets
  • Temperature changes that do not respond properly to HVAC controls
  • Clicking or repeated movement noises from the HVAC housing
  • Stuck or inconsistent blend door operation
  • Loss of proper mode selection in the cabin HVAC system

Installation Notes and Tips

Verify the vehicle year, make, model, and main position before installation. Because HVAC actuators are tied to the control system, confirm the replacement matches the original connector style and rotary activation design. After installation, cycle the HVAC controls to allow the actuator to relearn its range and confirm smooth operation. Part number 604-903 should be matched carefully to the listed fitment for Toyota Camry, Toyota Solara, Lexus ES300, and Lexus ES330 applications.
