What Causes the Wiper to Not Return to Its Original Position?

There are generally three main reasons why a wiper does not return to its original position: 1. Failure of the wiper drive motor; 2. External wiper failure; 3. Circuit failure. The wiper, also known as the windshield wiper, is a device used to remove raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. Below is some related information about wipers: 1. Wiper classification: Wipers can be categorized by their driving methods into mechanical, vacuum, pneumatic, hydraulic, and electric types. Modern vehicles typically use electric wipers, which are advantageous for their simple structure and convenient control. Generally, a car wiper consists of a motor, crank, linkage, wiper arm, and wiper blade. 2. Wiper function: The wiper is used to remove raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. Due to legal requirements, almost all vehicles worldwide are equipped with wipers. Rear windows of hatchbacks and SUVs also come with wipers.

Is it Necessary to Add Antifreeze in Hot Weather?

Even in hot weather, cars still require antifreeze as it possesses excellent properties such as preventing freezing in winter, boiling in summer, and offering year-round protection against scale and corrosion. Composition of Antifreeze: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally categorized into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can Different Antifreezes Be Mixed? It is essential to use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing and boiling points. Market-available antifreezes come in several freezing point specifications, such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region.

Is it normal to replace the battery after more than two years for Lavida Plus?

The battery of Volkswagen Lavida generally needs to be replaced every three years. Scenarios requiring a new battery: When driving, the car lights may not turn on, the horn may not sound when pressed, and sometimes the car may frequently fail to start. These indicate that the battery has aged and it's time to replace it with a new one. Hazards of not replacing the battery: Car batteries have a limited lifespan. If the battery is not replaced for a long time, it can lead to a shortened battery life, making it impossible to start the car. Precautions for replacing the battery: Pay attention to the parameters: one is the voltage parameter in front, and the second is the capacity parameter at the back. For ordinary passenger cars, it is basically 12 volts, and this must not be changed. The second is the capacity parameter at the back—the larger the capacity, the better, as long as it fits in the battery compartment. If the capacity is smaller than the original battery, it may lead to insufficient power supply or reduced battery endurance, causing the battery to fail easily or even damage other car components.

How Long Does It Take to Get a Driver's License Fastest?

Under normal circumstances, it takes about a month to get a driver's license at the fastest, while most people need two months to obtain it. This is because the driver's license exam has certain time restrictions when scheduling, and you can only schedule the exam after the specified number of days. Materials required for driver's license application: A copy of your ID card; non-locals need a copy of their residence permit. The applicant's "Motor Vehicle Driver's License Application Form," which can be obtained and filled out at the driving school. A medical certificate issued by a county-level or above medical institution, which requires a driver's license physical examination at a qualified hospital. Recent color photos of the applicant with a white background and without a hat. Driver's license test items: Subject 1: Road traffic safety laws, regulations, and related knowledge test. The structure of the test question bank and basic question types are formulated by the Ministry of Public Security. Subject 2: Field driving skills test, including reversing into a garage, stopping and starting on a slope, turning at a right angle, driving along a curve, and parallel parking. Subject 3: Road driving skills test, including preparation before driving, starting, driving straight, changing lanes, passing intersections, and parking by the roadside. Subject 4: Safe and civilized driving knowledge, covering related knowledge of safe and civilized driving.

Can Perfume Be Kept in the Car?

No, volatile items such as air fresheners and perfumes should not be kept inside the car. Especially in new cars, avoid placing perfumes and air fresheners because car perfumes and air fresheners are typically made by blending perfume or essential oils with industrial alcohol, which evaporates quickly and has a strong odor that can easily mask the smell inside the car. While the new car smell may disappear, the pollution inside the car worsens as the car perfume evaporates. Below is additional information: 1. Items to avoid in summer: When summer arrives, create a "blacklist" of prohibited items for your vehicle and clean them out to prevent damage. There are six main categories of items that should not be left in the car for extended periods during summer: bottled water, disposable lighters, reading glasses, carbonated drinks, car perfumes, and electronic devices. 2. Other consequences of keeping perfume in the car: Car perfume evaporation produces flammable gas, with an explosion critical point of 49°C. In summer, sunlight can raise the car's interior temperature to 65°C in just 15 minutes, easily triggering an explosion.

What does TC on the car dashboard mean?

TC in a car stands for Traction Control System. Here is the relevant information: Introduction to Traction Control System: The Traction Control System, also known as the Anti-Slip Regulation system. When a car brakes on a slippery road surface, the wheels may skid, even causing loss of directional control. During startup or rapid acceleration, the drive wheels may also skid, which can lead to loss of control and danger on icy or other slippery surfaces. The Traction Control System is designed to address these issues. The system relies on electronic sensors to detect when the driven wheels' speed is lower than that of the drive wheels, at which point it sends a signal to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or apply braking to the wheels, thereby preventing wheel skidding. How the Traction Control System Works: The working principle of the Traction Control System involves replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal's information to the ECU (Engine Control Unit). The ECU then generates a control voltage signal based on this information, and the servo motor adjusts the throttle accordingly, reducing its opening and controlling tire skidding. For vehicle owners driving in rainy or snowy conditions, this system can minimize occurrences of skidding or loss of control.
