Why does the car AC make a buzzing sound after turning off the engine in summer?

It is normal for the car AC to make a buzzing sound after turning off the engine in summer. This is to prevent the engine from seizing due to rapid cooling after shutdown. After driving for a while, various components of the engine reach high temperatures. If the engine is turned off immediately, parts like the cylinders and piston rings, crankshaft and connecting rods may stick together due to the high temperature. This can lead to a phenomenon known as "seizing" or "bearing failure" upon the next startup. Solution: If you have been driving for a long time, it is best to let the car idle for a few minutes before turning off the engine, allowing the engine temperature to naturally decrease. Precautions after turning off the engine: Cars have many external devices, and often people continue charging their phones or listening to music after turning off the engine. These activities drain the remaining power in the battery. If the battery is completely drained, it may result in the car failing to start.

What Causes the Abnormal Noise from the Right Front Wheel of a Car?

Here are the specific reasons for the abnormal noise from the right front wheel of a car: Foreign Object Accumulation: Excessive accumulation of foreign objects on the fender or sound insulation pad. When the car turns, the tire interferes with the foreign objects, resulting in abnormal noise. After cleaning the fender, the tire noise disappears. Screw Loosening: The fastening screws of the fender or sound insulation pad come loose, causing the fender or sound insulation pad to lift. When the front wheel turns, it interferes with and rubs against them, producing abnormal noise. It is necessary to check the fastening condition of the fender and sound insulation pad and eliminate factors such as looseness and lifting. Unauthorized Modifications: Unauthorized modifications to the car tires, such as replacing them with non-original size tires. For example, widening the tires or increasing their diameter. When the car turns, the tires interfere with the body at certain positions, causing noise. This poses a significant safety hazard, and the original size tires should be reinstalled.

Why Does a Car Horn Sound by Itself?

Car horns sounding by themselves are caused by faulty contacts in the horn, preventing the horn switch and relay from automatically disengaging. Below are the specific reasons why a horn may not sound: Poor Sealing Leading to Water Ingress: The horn is internally sealed, but if the sealing is poor, water vapor can enter during car washing, causing the contacts to become damp and malfunction. Poor Contact at the Electromagnetic Coil Terminal: The terminal connections of the electromagnetic coil inside the horn are made of aluminum. If the insulating varnish on the enameled wire ends is not properly removed or if the crimping of the terminals is loose, poor contact can occur, leading to the horn not sounding. Contact Erosion Due to Prolonged Use: Prolonged use of the horn can cause the contacts to erode, creating resistance. This reduces the current passing through the electromagnetic coil, preventing it from attracting the armature to vibrate the diaphragm properly, resulting in the horn not sounding. However, when the horn is pressed continuously, a momentary surge of strong current can still pass through the resistance, allowing the horn to work intermittently.

What are the causes of abnormal noise in BMW steering gears?

Here are the causes and solutions for abnormal noise in BMW steering gears: 1. Friction between the steering column and floor mats: The newly installed floor mats are too large and directly contact the steering column, causing friction as the steering column rotates. Solution: Adjust the position of the floor mats or replace them. 2. Contaminated power steering fluid: If the power steering fluid is too dirty, it will increase the pressure in the power steering system, leading to abnormal noise from the power steering pump. Additionally, when the hydraulic oil becomes dirty or deteriorates, the formed oil film cannot meet normal working strength, and the lubricating performance of the deteriorated hydraulic oil decreases, intensifying friction between metal parts and reducing their service life. Solution: Regularly replace the power steering fluid.

What to Do If Someone Parks in My Spot?

If your parking spot is occupied, you can call the contact number left on the car window by the owner. If you cannot reach the owner, you can call 114 or 122, or use the one-click car removal feature on WeChat or 12123. Areas where parking is prohibited: Yellow no-parking lines on the curb indicate areas where roadside parking or stopping is prohibited. The length of the line indicates the prohibited range. Yellow grid lines mark areas where parking is prohibited for any reason. These are typically used at intersections, entrances, and exits where temporary parking could cause traffic congestion. Special areas such as within 30 meters of bus stops, gas stations, emergency stations, and in front of fire stations do not allow temporary parking. Parking is not allowed at intersections, railroad crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, or within 50 meters of these locations. Parking is also prohibited on road sections with barriers between motor vehicle lanes and non-motor vehicle lanes or sidewalks, as well as at crosswalks and construction zones.

Does Car Insurance Cover Mechanical Failures?

Insurance companies do not cover natural wear and tear, corrosion, or electrical and mechanical failures of vehicles; however, they will compensate for vehicle body damage caused by such failures in an accident. Below are the specific details of car insurance: Compulsory Traffic Accident Liability Insurance: Compulsory Traffic Accident Liability Insurance is a mandatory insurance required by law for every vehicle owner. It provides the most basic insurance coverage in the event of a traffic accident. If an accident occurs, this insurance helps the owner cover the economic compensation that would otherwise be difficult to pay. The compensation amount is determined based on the owner's liability proportion in the accident and whether it resulted in personal injury or death. Vehicle Damage Insurance: Vehicle Damage Insurance covers damage to the insured vehicle caused by an accident while being driven by the policyholder or an authorized driver. The insurance company will provide compensation within reasonable limits. The premium for this insurance is closely related to the vehicle's purchase price and the number of seats. Third-Party Liability Insurance: Third-Party Liability Insurance covers compensation for bodily injury or direct property damage to a third party (excluding the driver and passengers of the insured vehicle) caused in an accident. The insurance company will compensate according to the stipulated regulations.
