Micra 1.3 Wipers just stopped working..

My other half has a 1.2 Micra on a 53 plate, the wipers just stopped working (in the park position)
Checked the fuse under the headlamp all ok, checked the motor arms all look ok, tested the voltage between ground and the Low and high inputs to the wiper motor 0 volts! however the "intelligent" line in (I think its orange) is measuring 12vs all the time. Any ideas????
