A worn HVAC recirculation door actuator can show up as ticking or clicking behind the dash, or as a recirculation button that no longer changes the air source. A blend door actuator, a blown fuse or the HVAC control itself can be behind these signs too, so find the cause before you buy.
The vehicles it fits include the 2016-2024 Lexus IS350 and the 2022-2024 Lexus IS500, along with many other Lexus models.
