Should power windows work for a few minutes with the ignition off?
Yes, most modern vehicles' power windows will work for a few minutes with the ignition off. This feature provides convenience to the driver and passengers, allowing them to adjust the windows even after the car's engine is turned off. The power windows operate using residual electrical power stored in the vehicle's battery until a timer limit is reached, typically ranging from a few minutes to several minutes. Afterward, the electrical system gradually shuts down to conserve battery power, and the power windows cease to function. This feature enhances user practicality during short stops or when parked while allowing essential systems to prioritize efficient power utilization. Check your vehicle's owner's manual for specific timing details related to power windows with the ignition off.
