What are the reasons for Infiniti air conditioning not cooling?
2 Answers
Infiniti air conditioning not cooling may be caused by: 1. The air conditioning refrigerant is depleted, leading to insufficient cooling and affecting the cooling effect. In this case, you can add some air conditioning refrigerant; 2. Refrigerant leakage. The air conditioning unit inside and outside the car may work normally, but there is no cooling effect. Check the air conditioning pipelines, air conditioning pump, condenser, and evaporator components for damage that may cause refrigerant leakage, and replace any problematic parts; 3. If the car air conditioning is not cleaned, various impurities may cover the condenser, preventing it from dissipating heat normally. This can lead to excessive pressure and temperature in the air conditioning system, causing the air conditioning pump to stop cooling. Use a high-pressure water gun to clean the condenser's heat dissipation fins, then dry it with a high-pressure air gun; 4. If the air conditioning filter is too dirty, it may block the filter, preventing most of the cold air from passing through, resulting in poor cooling effect. Therefore, it is necessary to clean or replace the filter regularly.
Last summer, while driving my Infiniti Q50, the air conditioning suddenly stopped cooling, leaving me sweating profusely. It turned out to be caused by a refrigerant leak due to aging seals in the system. The compressor might also fail, making a rattling noise as a warning sign. Additionally, a dirty condenser can affect heat dissipation, or a clogged cabin air filter may restrict airflow. I first checked the fuses myself—if blown, I replaced them—but most cases require professional tools to measure pressure. I recommend visiting a 4S shop for a thorough inspection as soon as possible, refilling the refrigerant and fixing the leak points. Performing maintenance before summer can prevent such issues, avoiding the misery of driving in scorching heat.
