Rear wiper not working. I had read elsewhere in this forum about broken wires in the rubber booted section of wiring loom which connects to top right corner of the hatch door so I pulled the rubber cover down exposing the wires and lo! a neatly cut wire! I rejoined wire with a short piece of similar guauge wire and wrapped all the wires with insulating tape for extra strength and now all OK. The wire appeared to have been neatly cut through as though it had got caught and snipped clean in half. I suggest it might be worth pulling down the rubber "boot" and wrapping wires together with insulating tape as a preventive measure.
