If the windshield wipers on your 1998 Jaguar XJ8 won't shut off, it may be due to a faulty wiper relay or a malfunctioning switch. Another possibility is a problem with the wiper motor itself that is causing it to continuously run. You can try removing the fuse for the wipers to stop them temporarily, but it's best to have the issue diagnosed by a professional to prevent further electrical problems. Checking for any stuck positions in the wiper control stalk may also help.
