Right, so I lifted the wipers up and tried them and they work, motors shafts etc all fine, but when they get to their finish position after the wash cycle and i flip the wipers back onto the lights they dont seem to sit right and dont move when I activate the wash when on the lights.
I tried moving them manually but they wont budge.
from the image below you can see the angle is off compared to how it should be, I think. Any ideas?
