What component operates the windshield wipers at all designated speeds?

The component responsible for operating the windshield wipers at all designated speeds is the control. This refers to the system that regulates the operation of the windshield wipers according to different settings chosen by the driver. The control receives input from the switch, which the driver uses to select the desired wiper speed, and then commands the motor to adjust the speed accordingly. This control is crucial because it ensures that the wipers can operate at various speeds for optimal performance in different weather conditions, enhancing visibility and safety while driving.

The switch is necessary for driver input but doesn't directly manage the wiper operation's speed. The motor performs the physical action of moving the wipers, but it operates based on the commands given by the control, meaning it cannot function at designated speeds without that regulation. The pump is related to windshield washer fluid systems but does not play a role in wiper speed regulation.
