Windshield Wiper Park Position Guides
There are two marks on the front windscreen which identify the parked positions of the windscreen wiper blades.
The marks are a tiny window in the black undercoating, about a 1.5mm x 10mm clear slit in the black coating. They are very inconspicuous until you have seen them, then they are clearly visible.
One mark is on the right side and one in the centre of the windscreen. There is no mark on the left side. The two marks can be used to reinstall the wiper mechanisms if they have been removed.
Note it is obvious that the same windscreen is used for LHD and RHD vehicles, hence the marks are only really useful for LHD cars. For RHD cars the position of the right mark can be measured and transferred to the left side as a guide.
The marks are difficult to photograph due to the reflections in the windscreen. The next figure is a composite of two photos taken from the front of a RHD car.
