What Causes the Wiper to Make Loud Noises and Not Clean Properly?
2 Answers
The reasons for the wiper making abnormal noises and not cleaning properly include the presence of an oil film on the windshield and deformation of the wiper arm. Specific explanations are as follows: Oil film on the windshield: When a vehicle is exposed to the natural environment, the tiny pores on the glass can enlarge, and over time, they may absorb exhaust fumes and oil mist from the air, forming an oil film. Simply relying on the wiper and windshield washer fluid is insufficient to remove the oil film; an oil film remover must be used. Deformation of the wiper arm: The motor drives the reduction mechanism to rotate, which in turn moves the wiper arm and blade back and forth to clean the windshield. If the wiper arm is deformed, the wiper blade cannot adhere tightly to the windshield, preventing it from removing dirt. In this case, replacing the wiper with a new one is necessary.
The wiper makes loud noises and doesn't clean well, which is a common issue I encounter while driving daily. The main reasons include: the wiper blades have aged and hardened, causing the rubber to jump and produce noise when wiping; oil film or dirt on the windshield surface increases friction, leading to poor cleaning and noise; the wiper arm tension is either too high or too low, causing the wiper to jump; sometimes, rust or insufficient lubrication in the wiper linkage causes it to stick. It's recommended to check and replace old blades every quarter, opting for silicone material for better durability, and ensuring the size matches the model to avoid incorrect installation. Use professional glass cleaner during car washes to remove oil and dirt, and park away from direct sunlight to delay aging. Safety comes first—faulty wipers can blur vision in the rain and easily lead to accidents. If any abnormality is noticed, stop immediately to address it or visit a repair shop. Regular maintenance saves money and hassle; don't delay until it affects driving.
