The wiper motor was parking on the wrong side, it also had to come out anyway for IVA, so ran through the GBS instructions to flip the side it parks on.
Straightforward instructions but the hardest part was getting the circlip off the shaft at the back, eventually managed with needle nosed pliers & learnt in the process these clips go back on over the shaft rather than pulling the opening past the widest part (make sense?) pulling the circlip opening past the widest diameter on its shaft bends it past its spring point of return:
Dismantle, then this white plastic cam which activates the park switch is removed and re-attached on the other side of the gear:
Hindsight - actually the wipers need to park on the drivers side due to the very flat dimensions of the windscreen, I should have left the park where it was! To make things worse the cir-clip which holds the main shaft in place doesn't like being re-used - pings off - and stops the wiper park from working; So I had to get a new one + fitting it means removing the wiper assembly from under the dash...
Its also even easier to change the park side by rotating the wiper gearboxes 180ยบ - depending how much space is available.
