What is a car windshield wiper and how does it work?
A car windshield wiper is a mechanical and electrical part whose job is to clean the windshield of a car on rainy and snowy days. On rainy and snowy days, you will realize the importance of having a windshield wiper more. This part protects you from accidents by cleaning the windshield.
Old models of wipers had a mechanical shape and structure and were controlled with a lever from inside the car cabin. But today’s wipers have a modern structure. These new wipers are completely electric and even have a water source. Using this water source, you can clean the glass from dust. Also, some new cars have wipers with a rain sensor, whose performance is unique in its kind.
Some cars also have wipers on the rear window and even on the headlights, which helps reduce road accidents on rainy days.
The wiper consists of several parts, each of which has its own tasks, and ultimately two wiper blades move on the car window with mechanical movement and clean it.
Moving the wiper blades requires a lot of force. To provide such power, a gear is connected to a small motor that can increase the torque of this motor by up to 50 times. On the other hand, the speed of rotation of the motor will be up to 50 times slower.
The force of this gear, through a connection, causes the wipers to move forward and backward.
On rainy and snowy days, you will realize the importance of having a wiper more.
The structure of the wiper blade
You have seen long-handled T-bars that have rubber blades. To collect water, after washing the floor, you drag the T-bar on the floor and collect all the excess water. The structure of the wiper with a rubber blade is also similar to a long-handled T-bar.
The two wiper blades have a rubber coating that, by moving back and forth and with full force, remove snow, rainwater and dust from the glass.
But these same rubber blades may lose their original firmness and texture due to heat and cold and over time, and may tear, crack, and even split. However, the wiper blade is no longer as effective as before and cannot be expected to clean the glass and may become dangerous in case of heavy rain.
If the wiper blade is defective, you must replace it.
Wiper Operation System
You have seen the lever located on the right side of the steering wheel of the car. A long lever with writings on it. Using this lever, you are able to control the movement of the wiper. For most wipers, there are three modes. Fast motion, slow motion, and intermittent motion with timing.
In the fast and slow motion of the wiper, its motor is on and works continuously. In intermittent mode, the wiper stops for a while and starts moving according to the timing of the motor. In new cars, the driver has the option to adjust the wiper’s intermittent movement according to weather conditions. But in modern cars, the wiper movement is adjusted with the presence of a rain detection sensor.
What are the signs of a car’s wiper failure?
The wiper does not work
There can be many reasons for the wiper not working. A broken wire, a burnt motor, a damaged fuse, and a connection in the wiper system are some of the reasons for it not working. You may have broken the wiper handle or cut the wire when you cleaned the car or when polishing the car. It is better to consult a car mechanic before replacing the wiper to check the problem.
The wiper moves with difficulty on the glass
Sometimes, the movement of the blades may be disrupted due to a problem with the wiper motor. If there is a problem with the wiper motor mounts, the blades move either too loosely or too tightly.
The wiper moves with a loud noise on the glass
This problem is due to the old wiper. When the wiper is old and worn out, it makes a loud squeaking sound when it moves on the glass. This sound is extremely annoying and to fix it, you need to replace the wiper blades.
The wiper washer does not work
Another problem that occurs with the car wiper is the wiper washer not working. We will examine the wiper washer problems below.
A proper wiper replacement should be done by a car repairman.
What is the reason for the wiper washer not working?
The car wiper has a water spray source that, using a pump connected to it, sprays some water on the glass at the driver’s command and cleans the glass by moving the blades.
But this same wiper washer system may sometimes have problems and not work properly. Problems with the car’s sprinkler system include:
Empty water source
