What relay goes to the rear windshield wipers?

The relay that controls the rear windshield wipers is typically called the "rear wiper relay." It is part of the vehicle's electrical system and is responsible for supplying power to the rear wiper motor when the rear wiper switch is activated. In some vehicles, this function may be integrated into the body control module (BCM) rather than a separate relay. Always consult the vehicle's owner's manual or service guide for specific details regarding the relay location and function.
