A used OEM BMW master window switch, part number 8029907—the front left unit that lets the driver operate all power windows from a single panel. Also known simply as the master switch or driver's window switch. This genuine part was removed from a donor BMW 645Ci, 650i, or M6 with either the 4.4L/4.8L V8 or the 5.0L V10 (S85) engine. A common failure point: worn switch contacts can make individual windows unresponsive or intermittent, so swapping in a known-good OEM switch restores full one-touch control.
