Why does the wiper move by itself without turning on the switch?

The wiper moves by itself without turning on the switch because the control switch is broken. Solution: Send it to a repair shop for fixing. The structure of the wiper is quite simple, mainly consisting of a brush and a motor, so failures are relatively rare. Even if the wiper malfunctions and stops moving, it is mostly due to a blown fuse. Simply open the fuse box, locate the wiper's fuse, pull it out, and replace it to continue using the wiper. Introduction to wipers: The wiper is an important accessory installed on the windshield, and its function is to clear rain, snow, and dust that obstruct the view on the windshield. Therefore, it plays a crucial role in driving safety. Wipers generally come in three types: vacuum wipers, electric wipers, and wipers with electronic control units. The drawback of vacuum wipers is that the speed of the wiper blade is unstable. When the engine's vacuum level decreases (for example, when the car is climbing a hill), the wiper blade may stop, blurring the driver's vision. Vacuum wipers were phased out in 1972 and replaced by electric wipers.

Do You Need to Press Both the Clutch and the Accelerator When Shifting Gears?

When shifting gears, you do not need to press both the clutch and the accelerator. However, if you do not press the clutch first before shifting, you will not be able to engage the gear. Forcing the operation will inevitably damage the transmission and the gear shift switch, leading to a series of issues such as reduced engine power and increased fuel consumption. Whether upshifting or downshifting, the correct procedure is: release the accelerator, press the clutch, shift gears, slowly release the clutch, and gently apply the accelerator simultaneously. Remember to fully depress the clutch when shifting gears to ensure a more thorough gear change. Starting: Press the clutch with your left foot, press the brake with your right foot, engage first gear, release the handbrake, then slowly release the clutch with your left foot. When the car starts to vibrate slightly, move your right foot to the accelerator pedal and gently apply some throttle while continuing to release the clutch. Once the car starts smoothly, fully release the clutch with your left foot and prepare to accelerate for the next gear shift. Upshifting: Release the accelerator pedal, quickly press the clutch pedal with your left foot, move the gear lever to the corresponding gear, release the clutch pedal, and while releasing the clutch, slowly press the accelerator with your right foot.

How to License an Old Motorcycle?

Licensing an old motorcycle is as follows: Process Introduction: Go to the local traffic fee collection office, fill out forms, and pay fees. Then proceed to the office building to pay the purchase tax, which is calculated by dividing the price on the vehicle invoice by 11.7%. Once you obtain the purchase tax certificate, the process is considered complete. Next, go to the traffic police department to apply for the license plate. The license plate fee is approximately 300-400, and there are additional fees such as inspection fees and registration fees, which vary by region. Documentation Introduction: You will need the vehicle's certificate of conformity and invoice. Bring the current owner's identity proof, vehicle purchase invoice, second-hand vehicle transaction invoice (as proof of vehicle origin), proof of vehicle ownership transfer, vehicle manufacturing conformity certificate or import certificate for imported vehicles, vehicle purchase tax payment or exemption certificate, and compulsory traffic accident liability insurance certificate. Then, fill out the application form at the local vehicle management office, submit the vehicle for inspection, and complete the registration process. According to Article 5 of the 'Motor Vehicle Registration Regulations', for the first-time application of a motor vehicle license plate and registration certificate, the vehicle owner must apply for registration at the vehicle management office in their place of residence.

Can I Add Fuel Additive After Refueling?

You can add fuel additive after refueling, but the additive may not mix evenly with the fuel in this case. It is recommended to add the fuel additive to the car's fuel tank before refueling at the gas station, following the recommended ratio. This way, the added fuel additive will quickly dissolve thoroughly under the impact and vortex stirring of the fuel, ensuring a more uniform mixture of the additive and fuel. Precautions for using fuel additives: Gasoline-type fuel additives should be added to the gasoline tank, while diesel-type fuel additives should be added to the diesel tank. The two should not be confused. The most economical method is to use the additive continuously for the first three to five times, adding the detergent in the proportion specified in the instructions each time. After driving approximately 3,000 to 5,000 kilometers (depending on road conditions and fuel quality), repeat the cycle by adding the additive continuously for another three to five times. Hazards of overusing fuel additives: Excessive use of fuel additives may increase carbon deposits in the combustion chamber, and in severe cases, may lead to engine knocking or detonation. Fuel additives are auxiliary fuel additives, and excessive use can worsen vehicle exhaust emissions. Therefore, it is important to pay attention to the quantity and quality of the fuel additive when using it.

What Causes the Buzzing Sound in a Car?

Common causes for a car making a buzzing sound are as follows: Common Causes: Exhaust pipe leakage: When there is a leak in the intake or exhaust pipe, the vehicle produces a louder roaring sound as the exhaust rate increases with acceleration. Dirty throttle valve: During acceleration, the engine load increases, requiring the throttle valve to open wider and more fuel to be injected. If the throttle valve fails to open to the optimal position due to dirt blockage, it can lead to poor air-fuel mixture ratio in the engine, resulting in noise during acceleration. Engine misfire: An engine misfire refers to one or more cylinders not functioning properly, typically characterized by insufficient vehicle power, severe shaking of the exhaust pipe, and a clear "popping" or thumping sound from the engine. Possible Reasons: Transmission issues: The buzzing sound during acceleration may not always come from the engine; it could also be due to worn transmission bearings or insufficient lubrication fluid, causing friction. Engine problems: If the buzzing sound indeed comes from the engine, check if the RPM is unusually high. If the RPM increases significantly while the vehicle speed rises slowly during acceleration, this usually indicates clutch slippage, requiring replacement of the clutch kit. If the noise occurs during steering, check for faults in the ball joint or power steering pump. If the noise appears during braking, it might be due to water ingress in the brake system, causing rust or debris on the brake pads. If the noise occurs when the air conditioning is on, inspect whether the air conditioning compressor pulley is slipping.

Is it necessary to apply for ETC?

It is necessary to install ETC. According to the regulations of the State Council, vehicles without ETC in 2020 will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they need to be activated first. During free holiday periods, ETC users can still use highways, and no fees will be deducted when passing through ETC lanes. ETC Deduction Principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks, achieving the goal of vehicles passing toll stations without stopping. All this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Low-carbon, vehicles pass toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, decreases the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More Policy Support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More Future Possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC adoption rate for passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration of deep integration between ETC systems and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for car owners. This means more application scenarios will support ETC usage.
