This feature automatically adjusts airflow in the cabin to prevent the windshield from fogging up and may be perceived by customers as irregular climate control functionality. To reduce fogging, the EWAFS functions include: the air condition (A/C) button may turn on and off automatically, recirculated air may turn off automatically in all air modes except MAX A/C, recirculated air may also turn on and off automatically in various airflow modes in order to improve heating or cooling efficiency, and in auto climate control, high humidity conditions may automatically engage A/C compressor, increase blower motor speed and/or direct more air to windshield. Continue to monitor the Workshop Manual (WSM) for EWAFS updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10200995-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10200995-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10200995","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"hvac","name":"Heating and air conditioning","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO SPORT","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_ford_bronco-sport"]},{"make":"FORD","model":"ESCAPE","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_ford_escape","2021_ford_escape"]},{"make":"FORD","model":"EXPEDITION","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_ford_expedition","2021_ford_expedition"]},{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_ford_f-150"]},{"make":"FORD","model":"MUSTANG MACH E","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_ford_mustang-mach-e"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator"]},{"make":"LINCOLN","model":"CORSAIR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_corsair","2021_lincoln_corsair"]},{"make":"LINCOLN","model":"MKX","year_from":2007,"year_to":2007,"match":"exact","vehicle_ids":["2007_lincoln_mkx"]},{"make":"LINCOLN","model":"MKX","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LINCOLN","model":"NAUTILUS","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_nautilus","2021_lincoln_nautilus"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_navigator","2021_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
