Detailed Description

This HVAC heater blend door actuator is designed for 2003-2007 Honda Accord temperature control systems with dual zone climate control and U.S.-built vehicles. It helps move the blend door so the HVAC system can regulate air temperature correctly across the cabin. If your Honda Accord has inconsistent heat, uneven temperature output, or a temperature door that no longer responds as expected, Dorman 604-880 is the replacement part to inspect.

This part cross-references Standard Ignition ADR4296 for the same application. The Dorman 604-880 also aligns with OE-style replacement needs for Honda Accord HVAC repair work where the original actuator has failed or become inaccurate.

What It Is Used For

• Restoring temperature control in the HVAC system
• Correcting a blend door that does not move properly
• Addressing inconsistent hot or cold air delivery
• Replacing a worn actuator that causes HVAC response issues
• Repairing climate control operation in a 2003-2007 Honda Accord, left main position

Installation Notes and Tips

Verify the vehicle year, model, position, and dual zone climate control configuration before installation. Confirm the connector style, terminal count, and terminal gender match the original unit on the Honda Accord. After installation, cycle the HVAC controls to allow the system to relearn actuator position if required by the vehicle.

Quality Assurance

Dorman manufactures this actuator as a precision-engineered replacement for the original blend door actuator used on the listed applications. Part number 604-880 is built to support OE-style fit and performance for the specified Honda Accord HVAC repair.
