Poor air conditioning performance despite normal pressure in cars is often due to insufficient refrigerant in the AC system, resulting in reduced cooling efficiency. It is advisable to inspect components such as the AC pipelines, compressor, condenser, and evaporator for any damage that may cause refrigerant leakage. Another diagnostic method involves adding fluorescent dye along with the refrigerant. After a week of vehicle use, inspect the AC system with a specialized UV lamp. Relevant information about automotive air conditioning includes: 1. Introduction: The automotive air conditioning system (air-conditioning-device), commonly referred to as car AC. 2. Function: It regulates and controls the temperature, humidity, air cleanliness, and airflow within the vehicle cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue. It also creates favorable working conditions for the driver, playing a vital role in ensuring safe driving as a ventilation device.

What should be paid attention to when traveling in rainy days?

When traveling in rainy days, try to avoid tunnels that are prone to water accumulation when planning the route. If it is really unavoidable, pay attention to the water depth scale of the tunnel. Once the water depth exceeds the allowable wading depth of the vehicle, do not proceed rashly. At the same time, try to avoid running over puddles with unknown depth and size, and try to choose the middle lane of the road. Because the terrain at the central raised part of the road is generally higher. Here is the extended information: Slow braking: When you find that the distance from the car in front is shortening, no matter what the reason is, immediately release the throttle to slow down, and put your foot on the brake pedal to prepare for braking. Do not stomp on it suddenly. If you feel the wheels locking up, immediately release the brake pedal and press again, with the force still increasing gradually.

What Causes the Sunroof to Not Close and Rebound?

If there are foreign objects in the sunroof slide rail, the owner only needs to clean them to solve the problem. If it is due to insufficient lubricating oil, excessive resistance will trigger the automatic anti-pinch function, resulting in the sunroof not closing properly, which can be resolved by lubrication. Regularly use a special cleaner or water to wipe the sunroof's sealing rubber strip to prevent premature aging. Here is additional information: Car Sunroof: Installed on the roof of the car, it effectively promotes air circulation inside the vehicle, allowing fresh air to enter, providing the owner with a healthy and comfortable experience.

Does Parking on a Slope Affect the Car?

Parking on a slope can cause the following harm to the car: 1. Impact on the suspension: When parking on a slope, the side facing downward bears greater pressure on the suspension. Over time, this can lead to uneven aging and stiffness between the front and rear suspensions, affecting ride comfort. 2. Damage to the handbrake system: The handbrake is the first to bear the brunt when parking on a slope. The handbrake works by pulling the brake shoes via a cable to secure the vehicle. When parked on a slope, the handbrake cable continuously bears the component of the car's weight parallel to the slope, which over time can cause 'fatigue' in the cable, affecting its performance. 3. Risk of rolling when parked on a slope for long periods: If parked on a slope for an extended time, the handbrake may age and fail at any moment. If the owner is not attentive, a rolling accident could indeed occur. Therefore, it is advisable to avoid parking on slopes whenever possible to prevent overuse of the handbrake.
