Thread: intermittent wiper setting

Hi all my 2002 discovery doesn't like the intermittent wiper setting if I turn the wiper to this nothing happens although I can hear a click under the dash. If I turn the wipers to the on position they wait a second or two then work and if I then switch back to intermittent wipers they work to. This has been an ongoing issue for sometime any help would be great and much appreciated thanks Phil.

Thanks discovery I will give it a clean on the week end.
