Replacing the rubber pads of the brushes
The service life of the rubber wiper blades is limited, as worn rubber blades damage the glass of your Fiesta. Therefore, always change the blades in the fall, as with each movement of the blades, road dirt, dried insect residues, and salt crust residues have a negative effect on the rubber of the blades, and under the influence of ozone and ultraviolet rays, the rubber hardens. If the clamping pressure of the windshield wiper arm is still normal, then dirty streaks are evidence that it is time to change the blade pads. Replacing them is not difficult. You can do almost all the maintenance work on the windshield wiper yourself, in most cases you will only need a screwdriver. If you come to the conclusion that the wiper malfunction is in the wiring, refer to the section "Electrical equipment".
