Wiper wackiness

[Jim the Sunderer]

Morning Jag-wargh chaps.

So my 98 XJ8 has an interesting problem-

With the sidelamps on, if I do a one wipe on the wipers it doesn't stop wiping.

I imagine there's an obvious fix for this, but I'm not an auto-electrician, so hopefully it's just a relay that needs replacing.


Any assistance would be smashing.
