Wiper blades are elements of window cleaning system. They are designed for cleaning the glass from dirt and dust, as well as to ensure proper visibility in adverse weather conditions.
Types of wiper blades
In addition, choosing the wiper blades for your car, pay attention to their size.
The wipers construction
The main element is a rubber wiper blade. It must be firmly pressed to the glass. In the framework structures this is achieved through the elastic plates and frame, in frameless - only by means of the plate.
The composite frame in the frame structure is a rocker arms fixed to each other by hinges. They are held together with blades and elastic plates by clamps. In the winter version of the wipers the frame structure is placed in a protective rubber boot.
In the frameless wipers the blade is imbedded into the solid plastic case. The wiper is pressed against the glass by a flat metal spring.
In hybrid wipers the frame is enclosed in a plastic shell.

Diagnostics
The part malfunction is easily identified. Damage, dirt and distortions can be seen with the naked eye.
Therefore, seeing that the glass is cleaned improperly, inspect the wiper work surface to estimate their fit to the glass.
Repair and replacement of wiper blades
Sometimes you can recover the part’s operability by cleaning.
In case when the parts failure is not due to pollution, it is necessary to change the wiper blades entirely, or (half cheaper) the blade rubber.
Replacement is not difficult, and you can easily handle it on your own. Just remove unusable wiper from the lever, by pressing the clip or latch attachment, and then install the new one.
