Check if the air conditioning system is malfunctioning. Here is the relevant information: 1. Reasons why the air conditioner does not cool: Lack of refrigerant. Car air conditioners need to be refilled with refrigerant every 2-3 years. Refrigerant loss is usually due to leakage. If the car air conditioner does not cool but starts cooling after refilling the refrigerant, consider whether there is a lack of refrigerant. Damage to the air conditioning flap. Damage to the air conditioning flap motor is a relatively common issue. If there is a problem with the flap motor, it is more troublesome. The flap motor is usually located in the middle of the instrument panel and serves as the main switch for the air conditioning vents. Even if the air conditioner can produce cold air, it can only come out through gaps, significantly reducing the cooling effect. 2. Solutions: Because the dust cover and filter screen accumulate a lot of dust, if not cleaned in time, it will affect the cooling effect and increase power consumption. Therefore, the filter screen should be removed promptly and cleaned in water to brush off the accumulated dust.

What does it mean when the vehicle body touches the parking space boundary line while driving?

It means that during the parking maneuver, the wheels have crossed the boundary line, resulting in test failure and requiring a retake. Below is more information about parallel parking: 1. Introduction: Parallel parking is a component of the second subject in the driver's license test. It is an increasingly common scenario in urban areas where many streets have designated parking spaces along the sides, known as 'parallel parking spaces.' 2. Operation requirements: The driver must maneuver the vehicle into the right-side parking space without the wheels touching the lane boundary lines or the parking space boundary lines. 3. Test criteria: If the vehicle body crosses the line after stopping in the parking space, 100 points are deducted. If the wheels touch the lane boundary lines while driving, 10 points are deducted. Failure to park within the space results in a 100-point deduction. Not activating the left turn signal when starting deducts 10 points. Stopping midway deducts 100 points.

Can New Energy Vehicles Charge During Thunderstorms and Rain?

It is best not to use charging piles during thunderstorms and lightning. When a new energy vehicle is charging, the working charging cable transmits a large amount of current, especially when it rains and the wires are in a damp state, which can increase conductivity. If a lightning strike occurs, it may hit the charging pile in use. Although the charging pile is grounded, a lightning strike could generate enormous current and voltage, potentially damaging the battery. Below is more information about new energy vehicles: 1. Introduction: New energy vehicles refer to vehicles that use unconventional fuels as power sources (or conventional fuels with new onboard power devices), integrating advanced technologies in power control and driving systems, resulting in vehicles with advanced technical principles, new technologies, and innovative structures. 2. Classification: They include four main types—Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEV, including solar-powered vehicles), Fuel Cell Electric Vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices).

What does it mean to successfully appeal a drunk driving charge with a breathalyzer reading of 50?

Successfully appealing a drunk driving charge with a breathalyzer reading of 50 refers to the right of every citizen to request a re-examination of the judgment if they disagree with the result. After the appeal is filed, the relevant authorities will accept it and conduct a re-examination. If there is no new evidence, the public security authorities have the right to reject the appeal. However, if new evidence proves that it was not a case of drunk driving, the public security authorities cannot refuse the appeal request and must accept the application. The standards for drunk driving and driving under the influence (DUI) are as follows: the alcohol standard for DUI is when the blood alcohol content of the vehicle driver is greater than or equal to 20mg per 100ml but less than 80mg per 100ml; the alcohol standard for drunk driving is when the blood alcohol content of the vehicle driver is greater than or equal to 80mg per 100ml.

Is It Worth Buying a Car If You Only Drive 5,000 Kilometers a Year?

Whether to buy a car depends on personal financial capability. A car is a consumable item, and its annual expenses include depreciation, fuel costs, insurance premiums, maintenance fees, parking fees, etc., which can be quite high. A car is not a necessity but rather a consumption upgrade—a form of discretionary spending. It is not just a means of transportation but also a personal item, a private space that cannot be measured in monetary terms. Below are some considerations when buying a car: 1. First, inspect the vehicle's exterior: Check for any obvious paint damage, ensuring there are no scratches, dents, or small pits on the body. Examine the seams of various parts of the car to ensure they are even. Open and close each door, hood, and trunk several times to check the mechanisms. Inspect the windows, headlights, and plastic components for cracks. Check the tires for wear and ensure the treads are intact. If unsure, compare them with the tires of other new cars. 2. Purchase car insurance immediately after buying the car: This includes compulsory traffic insurance (which also covers the vehicle and vessel usage tax) and commercial insurance. Although commercial insurance is not mandatory, it is advisable to purchase third-party liability insurance and vehicle damage insurance together. After purchasing insurance, you also need to obtain temporary license plates to legally drive to the DMV for official registration.
