Why can't the driver's window of the Buick Excelle be raised or lowered?

[LilaFitz]

Buick Excelle's driver's window cannot be raised or lowered due to the driver's side glass control lock being engaged or wiring issues. Below are specific introductions to Buick Excelle's warning lights: 1. Low fuel indicator light: When the fuel level in the tank is too low, the indicator light illuminates the triangular fuel tank symbol, which indicates the fuel filler cap is on the left side for convenient refueling. 2. Power adjustable steering system fault light: The indicator light illuminates, indicating a possible fault in the power adjustable steering system. If the steering system fails, the vehicle can still be steered but requires considerable effort. 3. Charging system fault light: The indicator light illuminates, indicating a charging system fault. When the ignition switch is turned on, this control indicator light comes on and should turn off shortly after the engine starts.
