Restore smooth temperature control from your Honda's climate system with the Dorman - OE Solutions HVAC Blend Door Actuator 604-885. This is the left main actuator, and it drops in as a direct-fit replacement for the 2005-2010 Honda Odyssey and 2006-2014 Honda Ridgeline. This small electric motor moves the blend door that mixes heated and cooled air to set the cabin temperature you select; when it fails, you may notice inconsistent air temperature, a clicking or knocking noise behind the dash, or a temperature setting that no longer responds.
- Direct replacement: engineered to install like the original air door actuator on the listed applications for correct HVAC operation.
- Position specific: many vehicles use several HVAC door actuators for different positions and functions — this is the left main unit, so review the application notes to confirm it matches the actuator you need.

- Trustworthy quality: backed by a team of experts and engineers in the United States and more than a century of experience.
