Track down the clicking behind the dash and keep cabin temperature steady with the Four Seasons HVAC Blend Door Actuator 73582 — the right-side unit that drives the Camaro blend door and positions the HVAC air door on command from the climate control system. It installs as a direct-fit replacement for the 2016-2019 Cadillac ATS, 2016-2019 Cadillac CTS, and 2016-2024 Chevrolet Camaro.
This small geared motor rotates the blend door inside the HVAC case to control how much air passes over the heater core, setting the temperature and mix you select. If a failed actuator is the cause of inconsistent cabin temperature, a stuck-open or stuck-closed door, or a repetitive knocking/clicking from behind the dash, this replaces it.
Includes: lever arm, gear, cam gear hardware and linkage as applicable.
Internal build: quality internal motor, drive gears, electronics and connections.
Tested: for function, durability and longevity.
Backed by Four Seasons: over 50 years of mobile A/C experience, built to match OE fit and function.
