This may be due to the interface between the window glass and the body mounted glass run. To correct this condition, replace the body mounted glass runs using the body mounted glass run kit (3 door: M2DZ-9821597-E, and 5 door: M2DZ-7821597-F) which contains updated seals for improved sealing performance. For claiming, use causal part 9821597/7821597 and labor operations 23943A and 23943A19 in Section 12 of the Service Labor Time Standards (SLTS) Manual.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11020052-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11020052-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11020052","components":[{"id":"structure-body","name":"Body and frame","parent":null},{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"wiper","name":"Wipers and washers","parent":"visibility"}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_bronco","2022_ford_bronco","2023_ford_bronco","2024_ford_bronco"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
