Audi door wiring harness, OEM part number 8E1971029AC, is a used genuine factory harness for the front left door. This assembly supersedes earlier versions including 8E1971029AA, 8E1971029AB, 8E1971029T, and 8E1971029AD. It connects the door's power windows, locks, speakers, and mirrors to the vehicle's main electrical system. A failing harness often causes intermittent window operation or non-responsive door controls. This harness fits A4, A4 Quattro, RS4, and S4 models with 2.0L turbo, 3.2L V6, or 4.2L V8 engines.
