Headlamp Washer Jet
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The headlamp washer jets are held flush with the front bumper cover by an internal spring. When the headlamp washer pump activates, it provides high pressure washer fluid to the headlamp washer jets. The high pressure from the washer fluid overcomes the spring force and extends the washer jet assemblies to apply high pressure washer fluid to the headlamp lenses.
