Audi front left door wiring harness, OEM part number 8T1971029L. This is a used genuine OEM harness from a donor vehicle. Also replaces a series of numbers including 8T0971029AB, 8T0971029AC, and others in the 8T1/8T2 prefix range. This harness carries power, signals, and data for the driver's door functions—window, lock, speaker, and mirror controls. When the original harness develops broken wires or intermittent faults, common symptoms include non-responsive window switches or door lock failure.
