Official summary
TSB: Some 2018 model year Camry and Camry Hybrid and 2019 model year Avalon and Avalon Hybrid vehicles may exhibit decreased front windshield defroster performance at extremely low ambient temperatures. This condition may be the result of the fresh/recirculation servo actuator separating from the servo. This condition does not affect the airflow of the defroster. Follow the Repair Procedure in this bulletin to address this condition.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
