Take command of your cabin comfort with the Dorman - OE Solutions HVAC Blend Door Actuator (P/N: 604-332), a direct-fit replacement for the 2005-2023 Toyota Tacoma. This small electric actuator drives the HVAC blend door, moving it to control the air temperature mix and airflow inside the cabin. This unit is cataloged for the MAIN position; because many vehicles use several actuators for different doors and functions, check the application notes to confirm it matches the position and function of the actuator you need to replace.
- Direct replacement: engineered to install like the original air door actuator on the listed applications to restore proper HVAC operation.
- Position specific (MAIN): vehicles often have multiple HVAC door actuators for different locations and functions — verify this one matches yours before ordering.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation and long service life.
- Trustworthy quality: backed by a team of experts and engineers in the United States and more than a century of experience.
If a failed blend door actuator is the cause of inconsistent temperature, a clicking noise behind the dash, or a door stuck on one setting, this replaces it.
