SSM 47814

Some 2016-2019 Explorer, 2016-2018 MKX, 2019 Edge/Nautilus, 2017-2019 Fusion/MKZ, and 2018-2019 F-150/Mustang/Expedition/Navigator vehicles equipped with climate controlled seats may exhibit a buzzing noise from the front seats, front seats too warm, and/or inoperative climate controlled front seats. DTCs B14BA:13, B1154:4B, and/or B14B9:13 may also be present. This may be due to loose terminal pin fit on the driver seat module (DSM) connector C341D (16 pin). If a loose terminal pin fit condition is found during normal diagnostics per Workshop Manual (WSM), Section 501-10, a new service pigtail connector (part number 3U2Z-14S411-BRAB) is available. Refer to Wiring Diagram, Cell 119 to make sure C341D is a 16 pin connector and not a 20 pin connector. Refer to Wiring Diagram, Cell 5 for the recommended splicing procedures.
