The reasons for the noise when wipers scrape the windshield are: 1. Wiper blades are made of rubber, which hardens and ages over time; 2. The wiper blades have not been in contact with water for a long time, making them dry; 3. There is debris between the wiper blades and the windshield; 4. The motor and intermittent relay affect the speed, causing friction if the movement is too fast or too slow; 5. The angle of the wiper arm is incorrect, causing the wiper blade to move irregularly on the windshield and produce noise. Solutions include: 1. Replacing the wiper blades; 2. Cleaning between the wiper blades and windshield; 3. Readjusting the position of the wiper arm. Wipers enhance driving safety during rainy weather. If there are issues with the wipers, it is recommended to repair them promptly to avoid accidents.

Is a Long-Term Fuel Trim of -14.7 Rich or Lean?

Long-Term Fuel Trim -14.7 indicates a rich condition. Below is additional information: 1. Fuel Standards: Typically, long-term fuel trim parameters range from -23% to 16%. A value of 0 means no fuel compensation is needed to achieve the correct mixture concentration. A positive value indicates the injection system needs to inject additional fuel, suggesting the engine's air-fuel mixture is lean, which usually makes the vehicle hard to start. A negative value means the injection system needs to reduce fuel to correct an overly rich mixture, so a negative long-term fuel trim indicates the vehicle's air-fuel mixture is too rich. 2. Long-Term Fuel Trim Standard: Generally ±5%. Exceeding this standard likely indicates an engine fault. If the vehicle's injectors are clogged, both fuel injection volume and atomization effect will be poor, resulting in a leaner combustible mixture in the engine cylinders.

Is it a problem if the clutch pedal doesn't spring back after being pressed down?

It is indeed problematic if the clutch pedal doesn't spring back after being pressed down. The specific reasons for the clutch pedal failing to return are as follows: 1. Poor return: Air entering the clutch pipeline system causes excessive clutch travel and poor return, mostly due to air entering the hydraulic system. In this case, the cause of the air entry should be identified as soon as possible, and the air in the hydraulic system should be expelled. 2. Dirty or contaminated fluid: This leads to severe wear of the internal piston of the clutch master cylinder or blockage of the return oil hole, preventing the clutch from returning. 3. Insufficient spring tension: As the vehicle's mileage increases, the clutch return spring may lose tension or break, causing the clutch pedal not to return. The symptom of this fault is a lowered clutch pedal height with reduced or no free play.

What kind of glue is used for tire sidewall repair?

Tire sidewall repair uses rubber. The following is an introduction about tires: 1. Introduction: A tire is a circular elastic rubber product assembled on various vehicles or machinery for ground rolling. 2. Function: Tires are often used under complex and harsh conditions. During driving, they endure various deformations, loads, forces, and high and low temperature effects. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the significant ability of tires to consume rubber.

Does exceeding the speed limit only at the endpoint count in section speed measurement?

Exceeding the speed limit only at the endpoint does count in section speed measurement. Here are the relevant details: 1. Section speed measurement: It calculates the average driving speed of a vehicle on a specific road section based on the time it takes to pass between two monitoring points. Therefore, as long as the average speed calculated at the endpoint speed measurement point is within the limit, it is acceptable. 2. Highways: Section speed measurement is generally used on highways to check whether a vehicle passes a specific speed measurement section in less time than the stipulated duration. If it does, it is judged as speeding. 3. Section speed measurement distance: For example, if the distance is 100 kilometers with a speed limit of 100 km/h, and the vehicle takes 1 hour to cover this distance, the average speed is 100 km/h, which does not count as speeding.
