Get your airflow moving to the right vents again with the Dorman - OE Solutions HVAC Blend Door Actuator 604-955 — a mode air door actuator that drives the HVAC door controlling where conditioned air is directed. It installs as a direct-fit replacement for the 2004-2010 Toyota Sienna (see the Buyer's Guide tab for engine-level applications), and is cataloged for the MAIN position. If a failed actuator is the cause of vents that won't switch or a mode door stuck in one setting, this replaces it.
- Direct replacement: built to restore proper HVAC operation on the listed applications by swapping in for the original air door actuator.
- Position specific: many vehicles use several different HVAC door actuators for different locations and functions — review this part's application notes to confirm it matches the MAIN actuator you need to replace.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation.
- Trustworthy quality: backed by a team of experts and engineers in the United States and more than a century of experience.
