Windshield Wiper blades are an essential part of any vehicle’s safety system. They are responsible for maintaining clear visibility through the windshield in inclement weather such as rain, sleet, or snow. Without functioning wiper blades, drivers would be unable to see obstacles on the road, making driving especially hazardous.
China’s auto industry standard QC/T 44-2009 “Automotive Windshield Electric Wiper” stipulates that the wiper, except for the wiper refills, should have a working ability. For the wiper rubber refills, it is required, not less than 5×10⁴ wiper cycles.
1.Actual replacement cycle of wiper blade
Generally speaking, the replacement cycle of the wiper is about 1-2 years. If only the wiper refills is replaced, it may have to be replaced once every six months to one year.
Moreover, many car maintenance manuals also stipulate that the wiper blades should be checked regularly.
For example, the Buick Hideo’s maintenance manual stipulates a 6-month or 10,000-kilometer inspection; the Volkswagen Sagitar’s maintenance manual stipulates a 1-year or 15,000-kilometer inspection.
2.Why is there no prescribed longevity of wipers
There are usually several reasons for the “life-span” of wipers.The first is dry scraping, which wears a lot on the wiper rubber refills.The second is exposure to the sun. Exposure to the sun will cause the wiper rubber refills to age and harden, and its performance will decline.
In addition, there are some improper operations that will damage the wiper arm and wiper motor, which should also be paid attention to.
For example, breaking the wiper arm hard when washing the car, freezing the wiper on the windshield in winter, and forcibly starting the wiper without thawing will cause damage to the entire wiper system.
3.How to judge whether the wiper blade should be replaced?
The first thing to look at is the effect of the scraper. If it is not clean, it must be replaced.
If the shaving is not clean, it can be divided into many situations. It seems that the screen of our mobile phone is not bright, it may be out of battery, or the screen may be broken, or the motherboard may be broken.
Generally speaking, refills of long and thin water marks are left after the wiper is scraped, most of which are the edge of the wiper refills is worn or there is a foreign object on the windshield.
If it is wiped down by the wiper, there are intermittent scrapes, and the sound is relatively loud, it is likely that the rubber refills is aging and hardened. If there are relatively large flaky water marks after scraping, it is likely that the wiper is not tightly attached to the windshield, the wiper is deformed, or the pressure of the wiper bracket is not enough.There is also a special case, that is, if there is an oil film on the windshield, it will not be scraped clean. This cannot be entirely blamed on the wipers.
In addition, you can also see if the wiper has abnormal noise. If the sound of the wiper motor suddenly increases, this may be a precursor to fault aging. In addition to the abnormal noise of the wiper motor, the hardening of the wiper rubber refills, the aging of the wiper arm bracket, and loose screws will also cause the abnormal noise of the wiper.
Therefore, if the noise of the wiper becomes louder than before when it is working, it is necessary to check these parts. If the wiper should be replaced, the wiper should be replaced, and the motor should be repaired, which can also reduce some safety hazards.
In general, the replacement cycle of the wiper is roughly 6 months-1 year, but whether it needs to be replaced or not depends more on the working status of the wiper. If the wiper is really not clean or there is a relatively large abnormal noise during the scraping process, it is best to replace it for driving safety.
