Wiper blades failures

• worsening of blades integrity;
• wear of blades because of intensive operation;
• reduction of blades downforce;
• deformation of the construction elements.

Signs of Wiper blades failures

• the wiper began to rustle when working;
• blades adjoin to the windshield insufficiently tightly;
• quality of glass cleaning decreased;
• stains and stripes when cleaning.

Causes of Window wipers failures

• influence of temperature changes and solar radiation;
• icing or soiling of the work surface;
• dry friction of blades over the glass;
• wear of fastening elements;
• use of poor-quality blades;
• influence of chemicals and fuel and lubrication materials;
• poor quality of the washing fluid or non-conformity of its composition to weather conditions.

Diagnostics

Visual inspection will help to estimate the blades condition; it is usually sufficient to pay attention to the condition of their surface.  So, you will be able to find the occurred deformations and other signs of wear. Trial starting of wiper will allow to get the exact picture of failure, but, when doing that, it is necessary to use washing fluid. In case if quality of cleaning will be unsatisfactory, then the blades should be replaced. The blades serve for about 4-6 months under normal operation conditions. Materials retain their properties during such term.  

Repair of wiper blades

The widespread problem breaking work of the wiper is ingress of fuels and lubricants and other chemicals onto blades. In this case replacement of blades won’t be always necessary. At first it is necessary to try washing out the pollutant with the help of twenty-percent warm soda solution. Widespread practice is usage of petrol and other solvents, but such substances are capable just to spoil the blades completely.

The design of the majority of the wipers used in modern cars allows to change only the rubber part of the blades. It is sufficient to find a suitable model only. Buying the blade rubber only, it is possible to reduce the costs of blades replacement almost twice.

Replacement of Wiper blades

Replacement of the blades will demand their removal from fixations. To do this, it is necessary to unblock the special clamp on the arm. This procedure won't demand special skills or knowledge, it  only requires a couple of minutes.

Experts recommend to perform replacement of blade rubbers simultaneously thus allowing to provide their uniform wear.
