Wiper Blade

Flat beam blades and conventional frame blades are common. The rubber edge wears and hardens over time. Rear wipers often have their own blade size. The correct length and adapter for each arm can be found in the owner's manual or a parts catalogue. Cleaning the rubber edge with a cloth and washer fluid removes grit that causes streaks. Lifting the arms in frost or using the service position avoids tearing blades frozen to the glass.

The rubber edge is pressed against the glass and pushes water aside.

Streaking, chattering or noise are signs of worn blades. Many manufacturers recommend replacing blades every year.
