This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k

Some 2021-2024 Bronco vehicles may exhibit a rattle from the front windows with the windows placed in the partially down position and driving over rough roads and/or bumps. 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.
SSM 53962	2025-06-24. Service bulletin. Some 2021-2025 Bronco vehicles may exhibit a water leak from the A-pillar, overhead console/upfitter switches and/or sun visors. If a leak is identified from this area, refer to Workshop Manual (WSM), Section 501-18 Pinpoint Test (PPT) G for water leak diagnosis. If the PPT leads to the replacement of the header seal, a revised header seal has been released for service (M2DZ-7803110-H) which contains a thicker consistent bead of butyl across the entire length of the seal. The header seal will need to be firmly depressed and massaged to make sure all of the butyl that is across the entire header seal will properly adhere to the body, creating a water-tight seal. For claiming, use causal part 7803110 and labor operation 03110A in Section 12 of the Service Labor Time Standards (SLTS) Manual.
