After a vehicle has driven through water, the air conditioning may stop cooling due to water entering the air conditioning pipes. To ensure optimal cooling performance, it is essential to maintain the dryness of the air conditioning pipes. Below is an introduction to the automotive air conditioning system: Air Conditioning Layout: Different types of air conditioning systems have varying layouts. Currently, most passenger cars use an integrated heating and cooling air conditioning system. This system combines components such as the evaporator, heater core, centrifugal blower, and control mechanism into a single unit, known as the air conditioning assembly. Air Conditioning Components: Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system. Automotive air conditioning typically includes components such as the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipes, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The automotive air conditioning system is divided into high-pressure and low-pressure lines. The high-pressure side includes the compressor output side, high-pressure pipes, condenser, receiver-drier, and liquid lines. The low-pressure side includes the evaporator, accumulator, return pipes, compressor input side, and compressor oil sump.

How to Determine if a Wheel Bearing is Faulty?

Tire bearing failure can be judged by the following methods: 1. A noticeable humming noise is a common symptom. If the humming sound persists and does not change when the vehicle speed increases to a certain level, it can be concluded that the tire bearing is faulty; 2. The car body may vibrate, with the vibration becoming more intense as the speed increases. Additionally, significant heat may be generated. After driving for a while, the driver can touch the tire to feel the temperature, which will be noticeably higher than normal. The main function of the wheel bearing is to bear the load and provide precise guidance for the rotation of the wheel hub. It withstands both axial and radial loads, making it a crucial component.

What are the reasons for the trunk popping open automatically?

The reasons for the trunk popping open automatically are: 1. Issues with the lock mechanism; 2. The latch is too dry and lacks lubrication; 3. The linkage rod inside the handle is not secured; 4. Damage to the trunk switch; 5. Problems with the electronic trunk lock contact; 6. Malfunction of the automatic trunk pop-up feature. The trunk lid is equipped with support devices like pneumatic struts, which function similarly to hydraulic-damped gas springs. When the trunk is locked, the locking mechanism applies a force that holds the trunk lid down, a force that the pneumatic strut cannot overcome. When the lock is released and the pulling force is removed, the pneumatic strut can then push the lid open. When lifting an unlocked trunk lid, it's essentially the gas spring assisting in raising the lid.
