What Causes the Noise When Rolling Up/Down the Windows of a New Car?

What to Do When the Car Window Suddenly Won't Close?

There are many reasons why a car window suddenly won't close. Here is a detailed introduction to some causes and solutions: 1. Damaged window lift motor or poor contact in the wiring harness: If you smell a burning odor when holding down the window button or hear unusual noises inside the door panel, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly contact a 4S shop or auto repair shop to replace the window lift motor. 2. Motor overheating protection: To protect the power supply circuit, window lift motors generally have an overheating protection mechanism. If components overheat for some reason, the motor will enter an overheating protection state, causing the window to malfunction. In this situation, simply wait for the motor to cool down. 3. Clogged tracks or aging rubber seals: Most cases of window glass not moving are caused by mechanical jamming. You only need to clean the tracks and apply some lubricant. 4. Lost initialization data: If the battery is disconnected or the power or ground wire of the window control module is disconnected during maintenance of other systems, the initialization data for the window may be lost, preventing the window from moving. In this case, the window lift needs to be reset. 5. Damaged window switch: The car window switch is one of the most frequently used switches in a car, as it is used almost every time you drive, so the probability of damage is also high. In this situation, simply replace the entire window switch.

Which Button is for Defogging on Rainy Days?

In the car air conditioning system, there are generally two buttons resembling a windshield. One is a rectangular windshield, representing rear window heating; the other is the front windshield defrost button. For manual air conditioning, turn on the front window defogging mode and the A/C switch, adjust the fan speed to maximum, and the fog on the glass will disappear shortly. More defogging methods: 1. Some models are equipped with electric heating for the rear window and external rearview mirrors. Simply turn on the electric heating, and the fog will clear in about a minute. 2. Automatic air conditioning: Press the one-touch defrost button. Related information: In winter, turning on the A/C can make it colder. You can also use the heating system for defogging. If the car has just started, avoid turning on the air conditioning immediately. Wait until the engine has warmed up for a few minutes, and the water temperature rises. Then, start the heating, set the fan speed to maximum, and also activate the front window defogging mode. The fog will disappear in a few minutes.

What Do Horsepower and Torque Mean?

Horsepower refers to the engine's power, while torque measures the amount of rotational force the engine can output in a single cycle. Here are the key differences between horsepower and torque: 1. Different meanings: Torque: Refers to the force that twists an object and causes deformation. It is the moment generated when an object is subjected to a tangential force in the direction of rotation, commonly measured with a torque wrench in Newton-meters. Common objects affected by torque include screw-nut pairs and drive shafts. Horsepower: A commonly used unit for measuring power in engineering, it indicates a car's top speed potential—higher horsepower means higher maximum speed. 2. Different characteristics: Higher horsepower results in greater maximum speed (Max Speed); higher torque means stronger instantaneous acceleration, making the car quicker during starts or sudden acceleration.

Will highways be closed due to rain?

Normally, highways are not closed during regular rainy weather. However, in cases of extreme weather conditions such as heavy rain or dense fog, temporary closures may be implemented to prevent accidents. Highways are typically closed only during natural disasters, severe weather conditions like strong winds, typhoons, or heavy snow, or in the event of serious traffic accidents. Precautions for driving on highways in rainy weather: 1. Stay alert: When driving on highways in the rain, in addition to staying focused, make sure to turn on the windshield wipers and defoggers to maintain clear visibility through the front and rear windshields for accurate judgment of road conditions. 2. Check your vehicle: Ensure your vehicle is in good condition. Beyond routine checks like brakes, steering, lights, dashboard, and tires, pay special attention to the windshield wipers during rainy weather to ensure all components are functioning properly. 3. Control your speed: During the rainy season, intermittent rain can leave roads wet and slippery for extended periods, reducing friction and impairing vehicle braking performance. Sudden braking can lead to skidding or loss of control. Drivers should maintain a moderate speed, typically between 80 to 90 kilometers per hour, and avoid sudden acceleration or hard braking during normal driving.

What to Do When the Windshield Wiper Doesn't Clean Properly?

There are many reasons why the windshield wiper may not clean properly. Below is a detailed explanation of some common causes and their solutions: 1. Excessive force from the wiper arm: The solution is to check the wiper arm spring. 2. Insufficient curvature of the wiper: The solution is to replace the wiper with poor curvature and purchase a wiper with better curvature. 3. Bird droppings or other particles on the windshield causing stains to spread when wiped: The solution is to clean the windshield with a cloth before driving and also wipe the wiper rubber clean. 4. Cracks on the wiper rubber: The solution is to replace the wiper.

How Long Does a Car Maintenance Take?

If the car owner has made an appointment in advance, each maintenance session can take as little as forty minutes or as long as two to three hours. The duration depends on the number of maintenance items and whether the workshop has available service bays. Therefore, it is recommended that car owners call ahead to make an appointment. Otherwise, even if you find free time for your car's first maintenance, you might discover that the 4S shop is fully booked or has no available service bays. If possible, car owners should try to schedule appointments on weekdays. Car maintenance items include: 1. Fuel Filter: The fuel filter is designed to remove impurities and water from gasoline, providing clean fuel to the engine and ensuring optimal performance. 2. Air Filter: The air filter is used to remove dust from the air. If larger particles enter between the piston and cylinder, it can cause a phenomenon known as "cylinder scoring." Therefore, a device is necessary to filter out airborne particles and dust. If the air filter is not replaced regularly, it can easily lead to insufficient engine air intake, reducing combustion efficiency. 3. Oil Filter: The oil filter is used to absorb debris, impurities, and moisture mixed in the engine oil. During engine operation, various frictions occur, producing debris that mixes with the oil. If the oil is not filtered periodically, it will directly affect the engine's lubrication. 4. Coolant: Coolant, also known as antifreeze coolant, serves functions such as antifreeze, anti-corrosion, anti-scaling, and anti-boiling, making it essential for normal engine operation. An overheated engine can reduce air intake efficiency and increase the tendency for knocking, while an overcooled engine can lead to decreased power and increased fuel consumption. Therefore, periodic coolant replacement is crucial for normal engine operation and reducing engine wear. 5. Gear Oil: Gear oil is a lubricant used for various gear transmissions, featuring properties such as anti-wear, viscosity-temperature stability, anti-emulsification, anti-foaming, oxidation stability, and rust and corrosion resistance. Gear oil is vital for maintaining transmission efficiency. 6. Power Steering Fluid: Power steering fluid is a special liquid in the power steering pump that automatically provides hydraulic steering force when the driver turns the wheel, ensuring smooth and effortless steering.
