Keep cabin temperatures under control with the Dorman - OE Solutions HVAC Blend Door Actuator 604-952, a direct-fit replacement for the 1999-2001 Toyota Camry and 1999-2003 Toyota Solara. This is the MAIN air-mix actuator: an electric motor that moves the HVAC blend (air-mix) door to control how much air passes through the heater core, setting the temperature of the air reaching the vents. See the Buyer's Guide tab for the full engine-level application list.
- Direct replacement: engineered to drop in like the original air door actuator on the listed years, makes, models and configurations.
- Position specific: many vehicles use several HVAC door actuators for different positions and functions — review the application notes to confirm this MAIN actuator matches the one 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.
Signs this actuator may need replacing include clicking or knocking behind the dash, temperature that won't change on one side, or airflow stuck hot or cold — if a failed blend door actuator is the cause, this replaces it.
