Windshield Wipers
WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
The windshield wiper relay in the BJB is energized when the ignition is on and provides voltage to the windshield wiper motor and the rain sensor. Based on the wiper/washer switch setting, the windshield wiper motor activates the appropriate wash, low, high and intermittent or rain sense modes. The logic of the wiper operation is contained within the windshield wiper motor.
