How to Fix a Jerky Wiper?
4 Answers
Lift the wiper blade along the angle of the windshield for a short distance. Lift the wiper arm outward, use one wrench to secure the head, and gently twist in different directions with another wrench. If it jerks when moving upward, adjust the bent head counterclockwise at the top. If it jerks when moving downward, turn it clockwise. Replace the car's wiper assembly in time to avoid abnormal noises.
My car's wipers have been sticking recently, and it took me a whole day to fix them. Usually, this is caused by a dirty windshield or worn-out wiper blades. I recommend first thoroughly cleaning the glass with detergent to remove any oil film, then spraying some windshield washer fluid to test the movement. If they still stick, the wiper blades might be deformed or worn out—simply replace them with a new set. Wiper blades available on the market for just a few dozen bucks are quite durable. Try to park in shaded areas to avoid direct sunlight, which can cause the rubber to deteriorate. Ignoring sticking wipers can be dangerous, especially when driving on highways in the rain, as blurred vision increases the risk of accidents. Don’t procrastinate until the rainy season to fix them. Personally, I check my wipers every quarter and replace them before they wear out completely—it saves both money and hassle.
Wiper blade stuttering is mostly caused by loose wiper arm screws or rusted linkage mechanisms. Long-term rainwater corrosion of metal components can lead to poor operation. In such cases, I usually first check if the wiper motor is functioning properly, using a multimeter to test current stability. If the motor overheats or makes abnormal noises, it may indicate internal gear wear requiring professional maintenance. Applying lubricant to linkage joints can also alleviate the issue, but if deformation is severe, it's best to visit a repair shop for a complete component replacement. Although stuttering may seem minor, it affects the entire system's reliability, and prolonged neglect can lead to motor burnout, costing more in the long run. Developing a habit of testing the wipers before driving is a good practice to ensure safe travels without unexpected troubles.
If the wipers are jerky, first clean the dust and stains on the windshield, then wipe the wiper blades with a cloth. I've noticed that rubber blades tend to harden and crack every six months of use, at which point you should replace the entire blade. Choosing silicone material is more durable than ordinary rubber. Regular maintenance, such as spraying some lubricant on the wiper joints when washing the car, can prevent rust and jamming. Preventive maintenance is key; a comprehensive check before each rainy season with small investments can avoid major issues.
