This may be due to the natural frequencies of the switch and bezel when excited by sound. To diagnose, perform Workshop Manual (WSM) Section 415-00 > Pinpoint Test E1. Use the 100Hz audio sample file from the Speaker Audio Test link within Pinpoint Test E1, and adjust fade and balance settings to passenger front speaker. If the rattle is isolated to the passenger door switch bezel, remove per WSM Section 501-11. Apply Rotunda flock tape (164-R4903) over the underside of the bezel and the switch in a U-shape, then reassemble. Rerun Pinpoint Test E1 to verify the repair. If the rattle persists, perform the remaining Pinpoint Test E steps.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10234135-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10234135-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10234135","components":[{"id":"structure-body","name":"Body and frame","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2023,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator","2022_lincoln_aviator","2023_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
