Keep cabin temperature and airflow under precise control with the Dorman - OE Solutions HVAC Blend Door Actuator 604-701. This small electric mode/temperature actuator drives the blend and mode doors inside the HVAC case, positioning them so conditioned air reaches the vents you select. It installs as a direct-fit replacement for the 2013-2019 Cadillac XTS and 2014-2020 Chevrolet Impala — see the Buyer's Guide tab for engine-level applications.
- Direct replacement: engineered to install like the original air door actuator on the listed applications and restore proper HVAC operation.
- Position specific: this actuator is cataloged in MAIN, AUXILIARY, RIGHT MAIN and LEFT MAIN positions — vehicles often use several HVAC door actuators, so review the application notes to confirm it matches the location 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.
- 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, air stuck on one setting, or a clicking sound behind the dash, this replaces it.
