What are the reasons for the X-Trail's air conditioning not cooling?

The reasons for the X-Trail's air conditioning not cooling are as follows: 1. Refrigerant leakage: Leakage of refrigerant in the air conditioning system leads to insufficient refrigerant, causing the air conditioning to fail to cool. You can check components such as the pipelines, air conditioning pump, condenser, and evaporator in the air conditioning system for any damage that may cause refrigerant leakage. Another inspection method is to add fluorescent dye along with the refrigerant. After using the vehicle for a week, inspect the air conditioning system with a dedicated UV lamp. If there are any leakage points, they will glow, indicating that the component is damaged. 2. Internal damage to the air conditioning pump: This prevents the cooling effect from being activated. Generally, a damaged air conditioning pump will produce abnormal noises. Therefore, check the air conditioning pump, and if it is damaged, it needs to be replaced. 3. Dirty condenser fins in the air conditioning system: This causes the pressure and temperature in the air conditioning system to rise too high. To protect the system, the air conditioning pump stops working, resulting in no cooling. You can use a high-pressure water gun to clean the condenser fins.
Last time I took my X-Trail for an outing, I encountered an issue with the air conditioning not cooling. It took me quite a while to figure it out. The most common problem is refrigerant leakage, which can happen due to aging pipe connections or a condenser damaged by stones. Another possibility is the compressor not working, which might be caused by a faulty electromagnetic clutch or a loose belt. The cooling system also needs to be checked. If the condenser in front of the radiator is clogged with willow catkins, the heat can't dissipate, and the air conditioning won't perform well. Don’t forget about the cabin air filter either. If it hasn’t been replaced in two years and is completely clogged, no air will come through, let alone cold air. Lastly, electrical issues like a blown fuse or a malfunctioning temperature sensor can also cause the air conditioning to stop working. I recommend checking the filter and condenser yourself first, but for more complex issues, it’s best to consult a professional mechanic.
