Reasons why the car won't start after stalling with AC on: 1. It is mainly caused by excessive carbon deposits on the idle speed motor, intake tract, intake valve, and combustion chamber. 2. Excessive carbon deposits and dirt in the intake tract can change the cross-sectional area of the air passage, resulting in an overly rich or lean air-fuel mixture. This leads to abnormal combustion or engine shaking after starting, or even failure to start. Alternatively, issues with the fuel injector, such as leakage or excessive carbon buildup, can cause a lean mixture during startup, making it difficult to start. 3. Additionally, if the carbon canister or carbon canister solenoid valve malfunctions, it can also lead to difficulty in starting.

Should I Install Window Tint or a Dash Cam First for a New Car?

It is recommended to install the dash cam first for a new car. Here are the detailed explanations regarding new cars: 1. Reason: The dash cam should be installed before window tinting because the adhesive in the window film requires some time to dry completely. During this waiting period, the car windows should not be rolled up or down, and excessive movement inside the car should be avoided. 2. Precautions: Installing a dash cam does not affect vehicle inspection. According to legal regulations, motor vehicles registered for road use must undergo regular safety technical inspections based on different circumstances. The inspection requires providing the vehicle's driving license and compulsory third-party liability insurance policy, and upon passing, an inspection compliance mark will be issued.

The car's interior uses a large amount of plastic, rubber, and other materials, and the organic solvents and additives in these materials gradually release into the car; 2. Odors caused by the air filter, where the air conditioner has been decomposed by bacteria, leading to mold; 3. Mold in the evaporator, requiring evaporator cleaning and air duct cleaning; 4. Eating or smoking in the car can also cause odors. Methods to eliminate odors inside the car: 1. Open the windows more often for ventilation; 2. Remove plastic packaging; 3.

Will the insurance company compensate for a car submerged in a natural disaster?

Insurance companies will compensate for a car submerged in a natural disaster. Here is the relevant introduction about auto damage insurance: 1. Introduction: Auto damage insurance refers to a type of commercial auto insurance where the insurance company compensates within a reasonable range for damages to the insured vehicle caused by an insurance accident while the vehicle is being used by the insured or an authorized driver. 2. Note: Auto damage insurance does not provide full compensation. Insurance companies set an absolute deductible in the auto damage insurance clauses based on specific circumstances and list liability exemption clauses. Currently, many insurance companies offer no-deductible insurance, allowing the insured to transfer the deductible amount they are responsible for in an accident to the auto insurance company, resulting in a higher claim amount for the car owner.

How many points are deducted for crossing a double solid line?

Crossing a double solid line results in a deduction of 3 points. Below is a detailed introduction to road traffic markings: 1. Double yellow solid lines: These are used to divide roads with two or more lanes in each direction without a central divider, strictly prohibiting vehicles from crossing the lines to overtake or driving over the lines. 2. Double yellow dashed lines: These are usually set at intersections and appear on roads with relatively low traffic volume. In sections with double yellow dashed lines, vehicles may cross the lines to enter the intersection after ensuring safety. 3. Double yellow lines with one solid and one dashed line: On the side with the dashed line, vehicles may cross to overtake or make a U-turn, while the side with the solid line must not be crossed or driven over. 4. Single yellow solid and dashed lines: Similarly, vehicles are prohibited from crossing the lines to overtake or driving over the lines. Single yellow dashed lines indicate that overtaking and U-turns are allowed when there are no oncoming vehicles and safety is ensured.
