What relay switch controls your wipers?

The relay switch that controls the windshield wipers is typically called the wiper relay. It is part of the vehicle's wiper control system, which includes the wiper motor and switch. When the driver activates the wiper switch, it sends a signal to the relay, which then activates the wiper motor to operate the wipers at the selected speed. In some vehicles, this function may be integrated into the wiper motor assembly itself rather than using a separate relay.
