Used Audi front left door wiring harness, OEM part number 8W7971029BL. This genuine harness routes power and signals for the window, lock, mirror, and speaker circuits inside the door. It replaces earlier versions 8W7971029BJ, 8W7971029CC, and 8W7971029CE. Common failure points are broken wires from repeated door flexing, causing intermittent window or lock operation.
