Fault Finding

WARNING: This page is about a different car, the 1993 Jaguar XJS. However, it is still accessible from the selected car via links, so may be relevant.

Inspect all fuses and connections. Ensure all ground connections are clean and tight. Because wiper motor is part of wiper frame assembly, terminal voltages must be monitored at connector socket. With ignition on and wiper switch at normal speed, battery voltage should be present at terminal 53 (Light Green/Brown wire) of connector socket. With wiper switch at high speed, battery voltage should be present at terminal 53b of connector socket.

NOTE: No additional testing procedures are available from manufacturer.
