Windshield Wiper Park

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The windshield wiper park switch is integral with the windshield wiper motor. The park switch ensures the windshield wipers return to the park position when the windshield wipers are switched off.

The park switch is part of the windshield wiper motor gear wheel. When the windshield wipers move from the park position, the park switch contacts are open. When the windshield wiper becomes near to the park position the park switch contacts are closed and a ground path to the BCM/GWM assembly is completed.

When the BCM/GWM assembly receives a LIN bus signal from the wipers and washers control switch that a wiper operation is selected the park switch status is continually monitored by the BCM/GWM assembly. If the wipers and washers control switch is moved to the off position, when the BCM/GWM assembly next senses the ground signal from the park switch, it will remove the power supplies through the wiper on/off relay, stopping the windshield wipers in the park position.
