wiper

I had nothing but bad experience with Bosch wiper blades, be it revolutionary, twin, aerodynamic, whatever. I stick with Champion and Valeo. But one word of caution: when it starts to streak, never rush to buy a new one. Get some alcohol and kitchen paper towel (it's better than Kleenex). Pour some alcohol on the towel, pinch it between your fingernails and literally scrape the blade edge, but hard. Dirt can stick to it with great force. You do this twice or thrice and lo and behold, you blade will probably return to its new condition immediately.

When it is not raining too hard, the water wiped to the left side of the window, comes back up because of the wind and hinders the view through the windshield. Other cars having only one wiper arm—namely Mercedes—have the resting position on the left side of the windshield. This can be achieved on the BX easily: remove the wiper arm and the plastic cover above the wiper and blower motors. Rotate the small iron arm of the wiper rod mechanism by 180° so that the spindle of the arm would rotate in the opposite position.
