What Causes the Wiper to Jerk in Low Gear?
4 Answers
Slow or jerky wiper movement is mostly caused by motor failure or damage to the linkage mechanism. Here is relevant information: 1. Introduction: The wiper, also known as the windshield wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. 2. Usage: On rainy days, when raindrops fall on the windshield, the view ahead is quickly obstructed, making vehicles, pedestrians, and scenery appear blurry. At this point, turning on the wiper will restore a clear view ahead.
There are various reasons for intermittent wiper operation at low speeds, an issue I frequently encounter. A common cause is rust or aging of the wiper arm linkage, resulting in uneven movement, particularly prevalent in older vehicle models. Another possibility could be carbon buildup or wear in the wiper motor, leading to unstable power output and causing judder. Oil stains or tree sap on the windshield can also increase friction, making the wiper blades stutter. I recommend first cleaning the glass and wiper blades, and checking if lubrication is needed at the connections. If simple maintenance doesn't resolve the issue, it might be an electrical control system problem, such as poor contact in the switch. Developing a habit of monthly inspections for wiper arm cleanliness can extend their lifespan. From a safety perspective, intermittent operation affects visibility during rain, and delayed handling increases accident risks. It's best to address the issue promptly to prevent worsening.
After driving for so many years, when encountering intermittent wiper operation at low speeds, I always check the linkage and motor first. Insufficient lubrication or rust on the wiper linkage can cause stiff movement; aging of the wiper motor may also lead to inconsistent rotation speed, especially during frequent wiper usage. Another reason could be deformed wiper blades or improper installation, causing uneven contact with the windshield and resulting in jerky motion. During daily driving, dirt buildup on the wiper arms exacerbates the stuttering, which I usually alleviate by cleaning them with a soft cloth. When dealing with such issues, don't overlook voltage checks, as system instability may occur under low voltage. Preventive measures include regularly replacing wiper blades and performing basic maintenance, which are low-cost but can save a lot of trouble. During safe driving, wiper stuttering can be distracting, so it's essential to address it promptly to ensure clear visibility.
Wiper stuttering at low speed is mostly caused by mechanical issues. For example, rust or bending of the linkage joints can make movement less smooth. Wiper motor failure is also possible—if the output torque is uneven, it can cause intermittent wiping. Dirty windshields or aged rubber blades are equally common, increasing resistance and leading to jerky motion. When I inspect it myself, I first clean the glass surface to ensure there’s no oily film. If that doesn’t help, I check for loose wiring contacts. Relatedly, voltage fluctuations can also trigger stuttering, especially in older vehicles. Simple maintenance like lubricating the arm shaft can prevent most problems. Don’t delay repairs, as it affects safe driving in rainy conditions.
