Detailed Description

This Dorman HVAC blend door actuator is made for select 2010-2015 Honda Crosstour and Honda Accord Crosstour models in the right main position. It is intended to restore proper temperature blend control inside the HVAC system by moving the blend door to the commanded position. The Dorman 604-878 follows the original actuator layout with a rotary drive, pin terminals, and a male 5-terminal interface for the listed applications.

What It Helps Fix

  • Inconsistent cabin temperature from the HVAC vents
  • Blend door movement that does not respond correctly
  • Temperature stuck on hot or cold in the right main HVAC zone
  • Clicking or repeated actuator movement behind the dash
  • Loss of proper air temperature mixing in the climate control system

Installation Notes and Tips

Verify the vehicle year, make, model, and right main position before installation. This actuator is specific to the listed Honda Crosstour and Accord Crosstour applications, so matching the connector style and terminal count is important. After installation, cycle the HVAC controls to confirm smooth blend door operation and correct temperature response.
