The basic function of a windscreen wiper is to remove rain, snow, and debris from the windshield to prevent impairment to the driver’s visibility. During rainy or snowy weather, the wipers move back and forth across the windscreen, dragging any particles or rainwater off the surface. The wipers are designed to clear the windscreen in a smooth and consistent manner.
Modern windscreen wipers are operated by an electric motor which moves the wiper blade back and forth across the screen. The motor is usually mounted on the firewall of the vehicle and is connected to a switch located inside the car, which is used to control the movement of the wiper. The switch has several modes, including intermittent, low, high, and off.
The wiper blade is made up of two parts: the wiper arm and the blade itself. The blade is typically made of rubber, which wears out over time, resulting in poor performance. This is why it is important to check the blades regularly and replace them when necessary. Worn out blades can cause streaks and leave significant areas of the windscreen uncleared, affecting the visibility of the driver and passengers.
When choosing replacement blades, it is important to consider several parameters such as the make and model of the car, the length of the blade, and the type of connector used to connect the blade to the wiper arm. Using the wrong blades can result in poor performance or even damage to the windscreen.
Apart from regular maintenance and replacement of the blades, it is also important to make sure that the whole wiper assembly is in good working condition. This includes the motor, the linkage, and the wiper arm. Any loose or damaged parts should be replaced immediately to ensure the optimal performance of the wipers.
In conclusion, windscreen wipers are an essential part of any vehicle, and their correct function is crucial for the safety of the driver and passengers. Regular maintenance, including the replacement of worn-out wiper blades and ensuring the good condition of the whole assembly, is necessary for optimal performance. By understanding the importance and function of this small device, vehicle owners can ensure that their wipers are always ready to keep them safe on the road, especially during challenging weather conditions.
