This may be due to the normal operation of the rear air duct vents. To determine if this is a normal condition, perform a road test at 40 MPH (65 Km/h) or above. Inspect if the noise is coming from the rear vents. During the road test alternate air conditioning (A/C) between fresh mode and air re-circulation mode. If the noise is eliminated when the A/C is in fresh mode, this is considered a normal characteristic of the vehicle and no repairs should be performed.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10222062-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10222062-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10222062","components":[{"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":2022,"match":"exact","vehicle_ids":["2021_ford_bronco-sport","2022_ford_bronco-sport"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
