GM-CRUZE-WIN-2026-01 Vehicle Application: Chevrolet Cruze (2008–2016 J300, 2016–2019 D2SC) System: Power Window Regulator, Driver/Passenger Front/Rear 1. Abstract The Chevrolet Cruze exhibits a common failure mode where a power window, most frequently the driver’s front, fails to roll upward while maintaining downward function or complete motor silence. This paper analyzes the three primary failure vectors: mechanical regulator failure, electronic motor/control failure, and wiring harness degradation (specifically the driver door jamb conduit). A step-by-step diagnostic workflow is provided to differentiate between a failed regulator, a faulty window motor, and a broken wire, culminating in repair procedures. 2. Introduction Owners frequently report a sudden inability to raise the window, often after lowering it. The window may move down but not up, move erratically, or produce a grinding noise. Unlike older vehicles, the Cruze uses a LIN-bus (Local Interconnect Network) controlled driver’s door module (DDM) communicating with individual window motors, making diagnosis more complex than simple switch testing. 3. Failure Mode Analysis Three distinct failure modes are observed in the field: The window may move down but not up,
