Hi 4rchibald, I have a 2009 (59) C5 VTR+ and the wipers have failed. The driver's side wiper does a small jerk but the passenger side wiper remains stationary, so I assume the nearside motor has probably failed. I've removed the motor from the car and was going to take a look inside - do you remove the black plastic lid on the top or the aluminium section screwed to the base, and how difficult is it to remove without breaking? Also do you still have any of the wiper motors you mentioned in your post? Thanks
