Dorman - OE Solutions HVAC Blend Door Actuator P/N:604-343

Restore proper HVAC airflow control with the Dorman - OE Solutions HVAC Blend Door Actuator 604-343, a direct-fit replacement for the 2005-2023 Toyota Tacoma. This is the MAIN position actuator — it drives the blend door that directs and mixes airflow inside the HVAC case so your climate settings respond correctly. Many vehicles use several different air door actuators for specific positions and functions, so review this part's application notes to confirm it matches the location and function of the actuator you need to replace.

• Direct replacement: engineered to drop in like the original air door actuator on the listed applications and restore normal HVAC operation.
• Position specific — MAIN: Tacomas often use multiple HVAC door actuators; verify this matches the position and function of the one you're replacing.
• 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.

Signs this actuator may need replacing include clicking or knocking behind the dash, temperature or airflow that won't change, or air coming from the wrong vents. If a failed blend door actuator is the cause, this replaces it.
