SSM 51263 2015-2023 F-150, 2017-2022 F-Super Duty, And 2019-2023 Ranger – Dust Ingress Into The Cabin
Some 2015-2023 Ford F-150, 2017-2022 Ford F-Super Duty, and 2019-2023 Ford Ranger vehicles may exhibit dust ingress into the cabin through the doors or air extractors. This may be due to the climate control system being in recirculation mode as a result of the recirculation button being on or automatic strategies for heating/cooling efficiency. To minimize dust ingress when driving in off-road or secondary road conditions, make sure that all doors and windows are fully closed, and the climate control system is switched to defrost on and the instrument panel and footwell air vents are switched to off. Temperature and fan settings may be adjusted as desired. Alternatively, max defrost can be activated which will adjust all settings automatically. Operating in defrost mode will keep constant air flow through the rear air extractors and other small areas, helping minimize dust ingress.
