Restore proper control over where your Toyota Sequoia sends its cabin airflow with the Four Seasons Mode Door Actuator, MPN 73638. This is the MAIN mode door actuator — the small electric motor that drives the blend/mode door in the HVAC case, shifting air delivery between the dash vents, floor and defrost outlets when you turn the climate dial. It drops in as a direct-fit replacement for the 2001-2007 Toyota Sequoia (see the Buyer's Guide tab for engine-level details).
Complete drive assembly: includes the lever arm, gear, cam gear hardware and linkage as applicable.
Quality internals: built with an internal motor, drive gears, electronics and connections.
Verified performance: tested for function, durability and longevity.
Backed by experience: supported by Four Seasons' decades of mobile A/C know-how.
If a failed actuator is the cause of a mode door that won't move, a clicking or knocking noise behind the dash, or air stuck coming from one set of outlets, this replaces it. Diagnose the cause before replacing, since other components in the HVAC system can produce similar symptoms.
