Windshield Washer Jets

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.

When the windshield wiper is switched off and the driver moves the wipers and washers control switch to the windshield wash position, the BCM/GWM assembly energizes the windshield washer pump. The BCM/GWM assembly will delay windshield wiper operation for 250 ms after the driver has operated the wipers and washers control switch in the windshield wash position.

When the windshield wiper is operating in either position, and the driver moves the wipers and washers control switch to the windshield wash position, the BCM/GWM assembly energizes the windshield washer pump, but the wiper sequence will not change.

If the driver operates the windshield washer jet for less than 250 ms, the BCM/GWM assembly will operate the windshield washer jet only.

If the driver operates the windshield washer for longer than 1.2 seconds, the BCM/GWM assembly will operate the windshield wipers for as long as the driver operates the wipers and washer control switch in the windshield washer position. The washer pump will only be powered for a maximum of 10 seconds. After the washer pump stops, the BCM/GWM assembly will operate the wipers to complete the current wipe cycle, and two further full cycles before park. After a four second delay, the BCM/GWM assembly will operate the windshield wipers for one full cycle to remove any residual washer fluid from the windshield.
