SWISSINT sells high-quality wiper blade rubber refill with graphite coating.
These are made of regular rubber but are simply coated with graphite,
a coal-like, semi-metallic element used in pencil lead.
When rubber is impregnated with powdered graphite, the blade is able to glide across
the glass more smoothly and quietly due to reduced friction.
Graphite also helps to protect the rubber from damage and deterioration.
BOSCH Aerotwin original rubber is also graphite coated.

BOSCH Aerotwin refill (rubber).
How to change the rubber on a Bosch Aerotwin® flat wiper blade.

SWISSINT sells high-quality wiper blade rubber refill with graphite coating. These are made of regular rubber but are simply coated with graphite, a coal-like, semi-metallic element used in pencil lead. When rubber is impregnated with powdered graphite, the blade is able to glide across the glass more smoothly and quietly due to reduced friction. Graphite also helps to protect the rubber from damage and deterioration. BOSCH Aerotwin original rubber is also graphite coated.

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.

Reset Automatic Windshield Wiper Function

  • Two people are required for this task as the doors have to be closed to reset this function.
  • First, pull and reseat your windshield wiper relays (locations are on the fuse diagram usually found in the tool compartment in your spare wheel well).
  • With engine running and all passenger doors closed, starting at 0 turn on wipers to #3 position, then put the switch in the 0 position then put it in the auto #1 (rain sensor position).
  • Then have your assistant splash water on the windshield.
  • The Automatic Windshield Wipers should now function normally.
