Windshield Washers

WARNING: This page is about a different car, the 2019 Jaguar XJ and 2018 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.

A windshield washer jet is located on each windshield wiper arm. The washer fluid feed hose from the windshield pump is connected to a 3-way valve connector located between the two jets. The 3-way valve acts to prevent washer fluid draining back to the windshield washer reservoir and also to limit the amount of washer fluid, which can be forced by gravity from the washer jets during cornering.

When the wipers and washers control switch is pressed and held, the windshield washer pump operates for a single pulse during the upwards movement of the wiper blades, this will continue until the button is released, or for a maximum of 10 seconds. The windshield wipers operate in conjunction with the washers, at normal speed, then for further wipes followed by a drip wipe. The amount of wipe cycles depends on the configuration.

When the driver operates the washer switch briefly the CJB energizes the windshield washer pump during the up stroke of the first two wash/wipe cycles. This makes sure that wiper fluid is pushed to the sides of the windshield and eliminates the trail of fluid which can occur if the fluid is pushed to the bottom of the windshield. The wipers will continue for further cycles, followed after a delay of 4 seconds, by a single dry wipe. The amount of wipe cycles depends on the configuration.

The drip wipe function operates the windshield wipers 4 seconds after a wash/wipe cycle has finished, to clear any remaining drips from the windshield. The drip wipe function can be configured using Jaguar approved diagnostic equipment.
