Rear Washer Operation

When the WASHER portion of the switch is pressed the rear washers are turned on, the switch has a momentary contact in the washer position and will continue to spray as long as the switch is being pressed and will stop when it is released. When the wiper portion of the rear wiper/washer switch is closed, B+ is applied to the REAR/WSW relay indicating rear washer operation is requested. With B+ applied to the relay coil, the relay is energized and B+ is supplied to the washer pump.
