So due to the wiper's not wiping on intermittent,common fault on primera,normally due to the grease in the motor tuning thick and dried up etc,i removed mine to drill out the rivet's holding the casing to the wiper motor etc as it's a seal unit,i re-grease it after cleaning it out,then bent out the contact's more while i was at it also.Next i needed to drill the casing of the motor to accommodate the new screw's that would replace the old rivet's etc,then i tapped the hole's i drilled to take the screw thread's,once i got that done,i put it back together,try the wiper's on intermittent,oh dear,still not working,so on the off chance i wiggled the motor loom and they worked on all setting's.So they sorted now,plus i now have a serviceable wiper motor that can be grease etc in the future just by removing the screw's that i have used instead of the rivet's like Oem.Which is handy.
