Four Seasons HVAC Recirculation Door Actuator P/N:73740
Take back automatic control over fresh-air and recirculated-air switching with the Four Seasons HVAC Recirculation Door Actuator (P/N 73571). This electric actuator drops in as a direct-fit replacement for the 2001-2007 Toyota Highlander — see the Buyer's Guide tab for engine-level fitment.
Mounted on the HVAC case, the actuator drives the recirculation door (flap) that selects between drawing in outside air and recirculating cabin air. If a failed actuator is the cause of a door that won't move, clicking behind the dash, or an air-source setting that won't change, this replaces it.
