BMW Door Wiring Harness, OEM part number 3508099 (also replaces 3413143). This used genuine OEM harness connects the door's electrical components—controls, locks, speakers, and lighting—to the vehicle's main wiring. A failing door wiring harness often causes intermittent window operation, broken power locks, or non-responsive switches. This specific harness fits left or right rear doors on the BMW X3 and is compatible with the naturally aspirated 2.5L and 3.0L I6 engines.
