Windshield Washer

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

When the windshield washer switch is activated, the SCCM sends the washer request to the windshield wiper motor over the LIN. The windshield wash relay is internal to the windshield wiper motor. When the windshield wiper motor activates the windshield wash relay, voltage is provided to the washer pump, directing washer solvent to the windshield. When the switch is released, the windshield wiper motor continues to activate for 3 additional wipes and then turns off.

If equipped with a front camera, washer solvent is also directed to the front camera lens when the washer pump is active.

There is an inline filter incorporated between the windshield washer pump and the camera washer nozzle.

The 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.

There are no check valves incorporated in the system to inhibit solvent flow.
