What causes intermittent cooling in the air conditioning of a 2013 Buick Excelle?

1 Answers

The reasons for intermittent cooling in the air conditioning of a 2013 Buick Excelle are as follows: 1. Insufficient refrigerant: This is the main cause of air conditioning malfunctions in most vehicles during summer. When the refrigerant in the car's air conditioning pipes is insufficient, the pressure in the pipes decreases, reducing the amount of heat removed. 2. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. If poplar catkins in spring or dust from smog accumulate on the condenser, it can lead to phenomena such as excessive engine temperature or poor air conditioning performance. 3. Loose air conditioning compressor belt: This condition is caused by aging of the compressor belt, resulting in slipping during operation, reduced efficiency, lower rotational speed, and poor refrigerant delivery. 4. Air in the air conditioning pipes: If air mixes into the car's air conditioning system during operation, it will affect the refrigerant's circulation, significantly reducing the cooling effect.

What do the basic automation levels L1 and L2 represent?

Basic automation L1 refers to driver assistance, which only allows the car to operate a very limited number of functions, while L2 is semi-autonomous driving, enabling the car to control multiple functions, with the remaining few functions requiring manual operation by the driver. Main functions of L1-level cars: L1-level cars can only perform a small portion of automated operations, such as setting a fixed speed, allowing the vehicle to appropriately accelerate or decelerate and make slight steering adjustments based on road conditions. The primary functions include adaptive cruise control, automatic emergency braking, and lane-keeping assist. Main functions of L2-level cars: L2-level automation offers a significantly higher degree of operational autonomy. Key features include ACC adaptive cruise control, active lane-keeping, automatic parking, road sign recognition, and automatic lane-changing. Compared to L1-level cars, L2-level vehicles can automatically start, stop, and follow based on obstacle detection, and they can also change lanes. The most notable difference is that L2-level cars can perform automatic parking.

What is the fault indicated by blue exhaust from the engine?

Blue smoke from the exhaust pipe indicates that the engine is experiencing an oil burning fault. The following are specific causes of oil burning: Worn valve seals: Over time, valves may wear out or age, and severe cases can affect the sealing performance of the valves, making oil burning more likely to occur. Excessive piston clearance: When a car has been used for a long time, carbon deposits from incomplete combustion may accumulate on the piston rings. If not cleaned for an extended period, this can cause the gap between the piston rings and the cylinder to expand, allowing oil to enter the combustion chamber and resulting in oil burning. In severe cases, this can even lead to engine seizure. Driving habits: Frequent rapid acceleration and prolonged high-speed driving can easily damage the lubricating oil film, leading to poor engine lubrication and wear on certain components, which may also result in oil burning. Excessive oil level: If the oil level is too high and exceeds the maximum mark, the excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form gummy carbon deposits.

Do I need to take the subject one test for a delayed license renewal?

If your driver's license has expired but not for more than one year, you do not need to take the subject one test. You can renew it directly after paying the fine. If it has been expired for more than one year, the license will be canceled. If the cancellation has not exceeded two years, you can apply to restore your driver's license and take the subject one test. Required documents: To renew your driver's license, you need to provide your ID card and a copy, the driver's license, a physical condition certificate, a photo receipt, and other materials. Renewal can be processed in a different location: The driver's license renewal can be processed at a vehicle management office outside the issuing location, meaning you can renew your driver's license anywhere in the country without providing additional proofs such as residence or temporary residence. However, please note that if the license has already expired, it cannot be renewed in a different location, and you must return to the issuing vehicle management office to process it.
