Wiper and Washer Systems: Testing and Inspection

The complexity of the electronics involved with the wipers and washers system preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the approved Jaguar diagnostic system for detailed instructions on testing the wipers and washers.

The approved Jaguar diagnostic system tests and analyses all functions of the wipers and washer systems. Where a fault involving the wipers and washer systems is indicated by the approved Jaguar diagnostic system, some basic diagnostic methods may be necessary to confirm that connections are good and that the wiring is not damaged, before installing new components.
