Restore steady, controllable cabin temperature with the Four Seasons HVAC Blend Door Actuator (MPN 73603) — the small electric motor many drivers search for as a Toyota Prius blend door actuator. It drops in as a direct-fit replacement for the 2001-2003 Toyota Prius and the 2001-2003 Toyota Prius / Prius AWD-E; see the Buyer's Guide tab for engine-level details. This actuator drives the blend door inside the HVAC housing to regulate how much air flows across the heater core, setting the temperature you dial in on the climate controls. If a worn actuator is the cause of clicking behind the dash, a temperature that won't change, or air stuck on hot or cold, this replaces it.
Includes as applicable: lever arm, gear, cam gear hardware, and linkage.
Quality internals: internal motor, drive gears, electronics, and connections.
OE-level fit: meets or exceeds OE specifications for fit and function.
Validated: tested for function, durability, and longevity, backed by decades of mobile A/C experience.
It's an electric motor that positions the blend door in the HVAC housing, controlling how much air passes over the heater core to set your selected cabin temperature.
