Dorman 604-365 HVAC Blend Door Actuator - Main
Dorman 604-365 HVAC Blend Door Actuator
The Dorman 604-365 HVAC blend door actuator is a direct replacement air door actuator for specific vehicle applications, including 2004-2009 Toyota Prius, Main position. It is built to restore proper temperature and airflow control when the original actuator fails or no longer responds correctly.
Because many vehicles use multiple HVAC actuators for different functions and locations, verify the position and application notes before ordering. The Dorman 604-365 is intended for the Main actuator location on the listed Toyota Prius years.
Key Features
- Direct replacement HVAC blend door actuator for the original unit
- Fits 2004-2009 Toyota Prius, Main
- Black plastic housing and black connector
- Rotary activation type with 5 terminals
- Male connector with female terminals
- Actuator arm included for proper HVAC door movement
- 4 mounting holes for vehicle-specific installation
Detailed Description
This HVAC blend door actuator, part number 604-365, is engineered for vehicles that need precise control of the air door inside the climate system. On the Toyota Prius, the actuator helps regulate how air is directed and blended through the HVAC case, supporting consistent cabin temperature control. The compact plastic housing measures 3.7 inches long, 3.12 inches wide, and 1.9 inches high, with a 1.83-inch actuator arm.
This part cross-references Four Seasons 73521 for the same application. If you are searching for a Toyota Prius HVAC blend door actuator, Dorman 604-365 provides a direct replacement option for the Main position on 2004-2009 Prius models.
What It Helps Fix
- Incorrect cabin temperature output
- Airflow stuck on one vent setting
- HVAC doors that do not respond to control changes
- Clicking or inconsistent actuator movement behind the dash
- Loss of proper blend door positioning in the climate system
Installation Notes and Tips
Confirm the actuator position before installation, since the Toyota Prius may use more than one HVAC actuator. Review the application notes for your vehicle and compare connector style, terminal count, and mounting layout to the original part. If the correct position is unclear, consult a qualified service technician before replacing the unit.
Quality Assurance
Dorman manufactures replacement parts designed to match original equipment fit and function for specific applications. Part number 604-365 is built as a direct replacement for the listed Toyota Prius HVAC actuator position.
