What component operates the windshield wipers at all designated speeds?

The component that operates the windshield wipers at all designated speeds is the control. This refers to the windshield wiper control system, which manages how the wipers function based on the driver's input, such as adjusting the speed settings for various weather conditions.

In this system, the control receives signals from the switch that the driver manipulates to select the desired speed of the windshield wipers. It then communicates with the motor, activating it to operate the wipers at the appropriate speed. Additionally, the control can include features such as intermittent settings, allowing the wipers to pause at designated intervals.

The switch is involved in the process, allowing the driver to select speeds, but it does not operate the wipers directly. The motor is the component that physically moves the wipers, but it relies on the control to determine how fast it should move them based on the driver's selection. The pump is unrelated to the wiper functionality; instead, it is typically involved in the operation of windshield washer fluid. Thus, the control is crucial for the operation of the windshield wipers across different speeds, ensuring that wiper performance meets the driver's needs in varying conditions.
