My rear wiper has started behaving oddly. when I switch it on, instead of going into intermittent mode, it performs 4 full wipes (no washer spray) and stops where it feels like - ie doesn't self park. Also when I unlocked it this morning with the plip, the rear wiper gave its 4 wipes for no good reason. Is this the onset of a comm2000 problem or could it be something on the wiper motor itself??
