Can anyone furnish me with a schematic / circuit for the windscreen wiper motor control etc. Mine works fine, except sometimes it just stops in the home position and no matter what I do to the stalk it point blank refuses to wipe, nothing except water, which I guess is separate. Once it starts wiping it's normal, no juddering etc, slow and fast. Mainly triggered by intermittent wipe which is my normal more having a rain sensor fitted. I have a Relay 3, 2008, 3.0Hdi 160ps box. Thnks..
