Loud noise when the wiper is activated is mainly caused by: 1. The spring of the wiper arm being too tight. 2. Excessive wear on the friction surface of the wiper blade. 3. The friction surface of the wiper blade being uneven or deformed. 4. Solutions: (1) If the spring of the wiper arm is too tight, the solution is to slightly stretch the spring. (2) If the wiper blade is worn or the friction surface is uneven or deformed, it is recommended to replace the wiper blade. (3) You can check if the frame holding the rubber strip of the wiper is slightly bent.

Oh I've encountered this issue several times! The wiper blades screeching against the windshield is absolutely maddening. The main reason is the aging and hardening of the wiper rubber – over time, the rubber loses its elasticity and creates that irritating friction noise against the glass. Oil film or accumulated dust on the windshield can also worsen the noise; I once discovered a layer of bug residue or tree sap on my windshield that caused the wipers to squeal sharply. Dry weather conditions make the screeching particularly noticeable – I recommend spraying some windshield washer fluid to moisten the surface first. Additionally, if the wiper arm is misaligned or the pressure is too high/low, problems can arise. The DIY solution is simple: first clean both the glass and wiper rubber with a damp cloth; if the noise persists, check if the wiper is deformed – replacing the rubber insert only costs a few dozen yuan. Delaying repairs may lead to windshield scratches which are even more annoying, so timely maintenance can save you a lot of hassle.

What is BRIDGESTONE tire?

BRIDGESTONE is the tire brand of Bridgestone Corporation, a product of Japan's Bridgestone Corporation, now widely used on various automobile brands worldwide. The Chinese translation is "Bridge Stone," which actually carries the meaning of "Stone Bridge." This name was derived from the surname of Bridgestone's founder, Shojiro Ishibashi. Currently, Bridgestone tires are applied to products of several Chinese automobile manufacturers such as Guangzhou Honda, Tianjin FAW Toyota, Zhengzhou Nissan, and Beijing Jeep. With production bases in 24 countries globally, its sales account for one-fourth of the world's total tire sales. Bridgestone has developed a new in-wheel motor drive system for electric vehicles, where the motor part functions as a shock absorber. Named "Bridgestone Dynamic-Damper type In-wheel Motor System," this system will be exhibited at the 60th Frankfurt Motor Show. The system's feature is that the motor is mounted on the axle via shock absorbers and springs. Relative to the axle's movement, the motor counteracts through reverse motion, acting as a dynamic damper. By offsetting the axle's vibrations, it enhances tire ground contact. To allow the motor to move vertically relative to the axle, four joint components called "crosshead guides," each configured with two linear guide slots in vertical and horizontal directions, connect the motor and the wheel. This ensures drive force transmission even with positional changes. Methods for Bridgestone tire maintenance: Enhance awareness of tire safety and inspect tires regularly. Regularly correct wheel balance; unbalanced wheels can cause high-frequency oscillations during high-speed driving, leading to uneven tire wear. Perform tire rotation periodically. To ensure even wear across all tires on a vehicle, rotate them every 5,000 kilometers. In daily use of Bridgestone tires, pay attention to the following: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves gradually shallow. If the tread wears flat, it loses its drainage and anti-skid functions, significantly reducing the vehicle's performance. Tiny cracks may become hazards for blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water for cooling. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, park to allow natural cooling. Never release air to reduce pressure or splash water for cooling, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent and abrupt braking to prevent accelerated tread wear caused by dragging between the tire and the ground.

Why is the air conditioning pipe outside the car very cold but not cold inside?

It may be due to insufficient refrigerant or a dirty air filter. Below are the relevant explanations: 1. Refrigerant: Refrigerant, also known as coolant or freon, is the medium substance used in various heat engines to facilitate energy conversion. 2. Function of the air filter: It ensures the air filter fits tightly against the housing, preventing unfiltered air from entering the cabin; it separates solid impurities such as dust, pollen, and abrasive particles from the air; it adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air; it prevents car windows from fogging up, ensuring clear visibility and safe driving for passengers; it provides fresh air for passengers, preventing them from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes.
