Windshield Wiper Slow/Fast/Flick Wipe

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.

Slow Wipe

When the driver moves the wipers and washers control switch to the slow wipe position, the Body Control Module/Gateway Module (BCM/GWM) assembly detects a Local Interconnect Network (LIN) bus message and energizes the wiper relay. The relay is in the left EJB . The relay supplies power to the windshield wiper motor through a resistor. The motor will operate at slow speed until fast speed is selected or the wiper on/off relay is de-energized, removing the power to the windshield wiper motor.

Fast Wipe

When the driver moves the wipers and washers control switch to the fast wipe position, the BCM/GWM assembly detects a LIN bus message and energizes the slow/fast wiper relay in the left EJB . The fast/slow wiper relay contacts supplies the power directly to the windshield wiper motor, bypassing the resistor used for the slow wipe. The windshield wiper motor will operate at fast speed until slow speed is selected or the relays are de-energized, removing the power to the windshield wiper motor.

Flick Wipe

When the driver moves the wipers and washers control switch to the single wipe position, the BCM/GWM assembly detects a LIN bus message and energizes the wiper on/off relay in the left EJB . The motor will operate at slow speed until the wipers and washers control switch is released from the flick wipe position. The on/off relay is de-energized, removing the power to the windshield wiper motor.
