Wiper issue

hopefully a simple one to solve however the front wipers don't switch off when in the off position and wipe intermittently

They vary in speed as i adjust them however just won't go off, pulled the fuse in the meantime

any ideas? dodgy earth or faulty stalk perhaps?

Thanks

Most wiper motors have a park switch integral to them which allows the wipers to park when switched off, sounds like that maybe at fault. All though I've no experience of the Coupe system and haven't a wiring diagram to work it out.
