Keep your cabin at the temperature you dial in with the Four Seasons HVAC Blend Door Actuator 73429. This small electric motor drives the HVAC blend (air-mix) door inside the climate case, positioning it to control how much air flows through the heater core. It installs as a direct-fit replacement for the 2013-2019 Cadillac XTS, 2014-2020 Chevrolet Impala, and 2008-2020 Freightliner Cascadia, and is cataloged for the MAIN actuator position — see the Buyer's Guide tab for engine-level fitment.
If a failed actuator is the cause of clicking or knocking behind the dash, a temperature that won't change, or air stuck hot or cold, this hvac blend door actuator replaces the worn original. Diagnose the cause before replacing, since these symptoms can have other sources.
- Assembled unit: includes the lever arm, gear, cam gear hardware and linkage as applicable.
