Detailed Description
This Dorman HVAC blend door actuator, part number 604-378, is built for vehicles that use a specific air door actuator position and function. Many vehicles use multiple actuators in the HVAC system, so correct position matching is important when replacing a failed unit. For the listed applications, this part supports the Main position on 2000-2006 Honda Insight and 1997-2001 Honda CR-V models. This part cross-references Honda OE number 79140S04G01 for the same application.
What It Helps Fix
- Temperature stuck hot or cold due to blend door control failure
- Airflow that does not respond correctly to HVAC settings
- Inconsistent cabin temperature adjustment
- HVAC mode or blend door movement problems caused by actuator wear
- Noise from a failing actuator motor or gear set
Installation Notes and Tips
Verify the actuator position and function before ordering, since the HVAC system may use more than one actuator. Confirm the connector style, terminal count, and mounting points match the original unit on your Honda Insight or Honda CR-V. If the correct actuator position is uncertain, consult a qualified service technician before installation.
Quality Assurance
