How to Identify the Production Year of Car Glass?

There is a code located at the bottom left or right corner of the car window glass, with a digit and several small black dots in the last or second-to-last row. The digit represents the production year of the glass, indicating the last digit of the year, while the small black dots denote the production month. More detailed information is as follows: 1. Many car owners are aware that the markings on car glass include the production date, especially for those involved in appraising or purchasing used cars. Identifying the production date of car glass helps determine whether the glass has been replaced. 2. The production date of car glass can be determined by examining the code at the bottom left or right corner of the window glass, specifically the digit and small black dots in the last or second-to-last row. First, the digit indicates the production year, representing the last digit of the year. The small black dots signify the production month. Upon closer inspection of other vehicles' glass, you may notice that some have the black dots before the digit, while others have them after. If the black dots are before the digit, subtract the number of dots from 7. If the black dots are after the digit, subtract the number of dots from 13. The result will be the production month. Some glass may also have additional large black dots following the production year and month, which indicate the specific week of the month. For example, 5 dots represent the first week, 4 dots the second week, 3 dots the third week, and so on.

What Causes Steering Wheel Noise When Turning?

Steering wheel noise during rotation can be caused by various factors such as aging of the tie rod end ball joint, loose stabilizer bar bushings, dirty power steering fluid, or lack of lubrication in the shock absorber top bearing. Below are detailed explanations for the causes of steering wheel noise when turning: 1. Lack of lubrication in shock absorber top bearing: If the noise seems to come from outside the vehicle when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. You can verify this by opening the hood and listening if the noise originates from the shock absorber top mount area. Applying grease may solve the issue, but if the noise persists, replacement is necessary. 2. Loose stabilizer bar bushings: If the noise isn't from the shock absorber bearing, check the stabilizer bar bushings for looseness or damage. Loose or damaged bushings will not only cause noise during steering but also when driving over rough roads. Looseness can sometimes be fixed by adding shims, but damaged bushings require replacement. 3. Dirty power steering fluid: Contaminated power steering fluid increases system pressure, leading to a humming noise from the power steering pump. The solution is to replace the power steering fluid promptly. 4. Aging tie rod end ball joint: Worn tie rod end ball joints can cause both steering wheel vibration and noise. This typically requires replacement of the tie rod end followed by a four-wheel alignment.

What is the LOCK switch?

LOCK is the steering wheel lock position. There are four positions on the car's ignition keyhole: LOCK, ACC, ON, and START. LOCK position: The lock position, where the key is inserted and removed. In this position, all circuits except the anti-theft system and interior lights are completely turned off, and the steering wheel is locked. ACC position: The accessory power position, such as the cigarette lighter, radio, lights, and CD player. When the key is turned to this position, the accessory circuits are activated, and devices like the radio can be used. ON position: The power-on position. When the key is turned to this position, all vehicle circuits are activated, and the system prepares for engine startup and performs necessary self-checks. The key remains in this position during normal driving. START position: The engine start position. When the key is turned to this position, the starter circuit is activated, causing the engine to crank and start. Upon release, the key automatically returns to the ON position.

What Causes Transmission Noise?

Noise may occur due to incomplete clutch disengagement. For manual transmissions, the first possible cause of noise is incomplete clutch disengagement. The second possibility is the presence of gear debris, where fragments between gears continuously collide, or it could be damaged gears. More detailed information is as follows: 1. For automatic transmissions, the issue might lie with the gear set, requiring prompt repair. Automatic transmission fluid should generally be replaced every 2 years or 40,000 kilometers. Manual transmissions, however, require maintenance every 3 years or 60,000 kilometers. For a repaired transmission, it is strongly recommended to perform the first service at 3,000 kilometers, followed by replacement every year or 20,000 kilometers thereafter. 2. Transmission fluid operating under high temperature and pressure can accumulate sludge and impurities, causing the fluid to thicken and lose its fluidity. This reduces the protective layer between components, leading to direct friction and increased mechanical wear, which results in noise. If the noise is rhythmic, try accelerating. If the noise intensifies, it is likely due to gear surface peeling or broken teeth, or possibly incorrect installation during repair, and should be inspected promptly. 3. If noise occurs in neutral but disappears when the clutch pedal is pressed, it is usually due to wear or looseness in the front and rear bearings of the transmission's input shaft, or noise from the constant mesh gears. If noise persists in all gears, it may be due to the rear bearing of the output shaft. Severely worn or damaged bearings should be repaired or replaced. If irregular noise occurs at low speeds, assess the noise level. Loud noise may indicate poor gear meshing inside the transmission, necessitating removal and inspection.

What does tbox failure mean?

tbox failure refers to a problem with the vehicle's T-BOX in the telematics system. To determine the specific fault information, you need to visit a 4S shop to check the fault codes. Here is some related information: 1. Common tbox failure issues mainly include: damaged radar probes, which can be resolved by replacing the radar probe; inability to retrieve vehicle information and inability to adjust or query car information via a mobile phone. 2. Definition of tbox: tbox is short for TelematicsBOX, referring to the intelligent vehicle terminal in the telematics system. 3. Function of tbox: It communicates directly with the vehicle's CAN bus to obtain body status and vehicle condition information, uploads these data parameters to the TSP backend, or receives instructions from the backend and returns execution results. The tbox can also be used to communicate with mobile apps, enabling the display and control of vehicle information through the app.

How to Use the Windshield Washer Switch?

The windshield washer switch of a car is located on the control lever on the right side of the steering wheel, which is the wiper control lever. Push this lever forward to activate the washer spray. For some vehicles, you may need to pull the lever backward to spray water. More details are as follows: 1. The washer is connected to the windshield washer fluid reservoir, which contains a water pump. Windshield washer fluid is a car product that every car owner will encounter during vehicle use. The windshield washer fluid needs to be added to the reservoir, which is located in the engine compartment. 2. Windshield washer fluid has cleaning and antifreeze functions. It can clean stains and dust on the front windshield, preventing the driver's vision from being affected. The antifreeze function is to prevent the washer fluid from freezing in winter. If the washer fluid freezes, it may damage the reservoir or the pipes. When liquids freeze, their volume expands, which can easily cause damage to the reservoir. 3. It is recommended to choose a product with a sufficiently low freezing point when using windshield washer fluid in winter. The freezing point of the washer fluid is indicated on its packaging, so be sure to check it carefully when purchasing in winter. Refill the washer fluid promptly when it runs out; otherwise, it may affect the driver's ability to clean the front windshield.
