Rear wiper pausing

Got a weird problem with my rear wiper. For the past week or so it's stopped wiping smoothly

By that I mean when I switch it on the wiper wipes halfway across and then stops. If I cycle the switch again it carrys on for a bit and so on and so forth. It seldom ever stops in the right place and it never finished a complete wipe from top to bottom and back again

Strangely enough it wipes perfectly while holding down the rear wash option

Any ideas?
