Take back control of your cabin comfort with the Four Seasons HVAC Blend Door Actuator / Mode Door Actuator (MPN 73700), a direct-fit replacement for the 2016-2020 Cadillac CT6. This is the auxiliary position actuator — a small electric motor that drives the HVAC air doors to control temperature blend and airflow direction inside the housing. If a failed actuator is the cause of clicking or knocking from behind the dash, air that won't change temperature, or a door stuck on one setting, this unit replaces it.

  • Built to OE-level fit and function for the listed application.
  • Includes: lever arm, gear, cam gear hardware and linkage as applicable.
  • Quality internal motor, drive gears, electronics and connections.
  • Tested for function, durability and longevity, backed by Four Seasons' decades of mobile A/C experience.

Diagnose the cause of an HVAC fault before replacing, as clicking or temperature problems can also stem from a stuck door, wiring, or the control head. Confirm this is the auxiliary actuator your 2016-2020 Cadillac CT6 needs.
