Rear Window Washer
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.
When the rear window washer switch is activated, the rear window washer pump directs washer fluid to the rear window. The rear window washer pump shuts down when the switch is held active for 10 seconds. The washer can be reactivated by releasing and then reapplying the switch.
