What are the reasons for the sudden failure of the Ford Edge air conditioning to cool?

Ford Edge car air conditioning not cooling reasons and solutions: Insufficient or too little refrigerant: A common reason for car air conditioning not cooling is insufficient or too little refrigerant, which is likely caused by minor leaks. It is necessary to replenish the refrigerant. Excessive refrigerant: Too much refrigerant can also cause the air conditioning not to cool. There is a required proportion of refrigerant volume in the air conditioning system. If the proportion is too high, it will affect heat dissipation. You can slowly release some from the low-pressure side maintenance port of the air conditioning system. Loose drive belt: If the drive belt is loose, the compressor will slip during operation, leading to a decrease in transmission efficiency, a drop in compressor speed, and a reduction in refrigerant compression delivery, resulting in the car air conditioning not cooling. If the compressor drive belt of the car air conditioning is too loose, it should be tightened.
A few days ago, the air conditioning in my Edge suddenly stopped working, and I almost suffered heatstroke while driving on the highway. There are many common causes: insufficient refrigerant could be the main issue—check the pipes for any signs of leaks; compressor failure is also common—listen for unusual engine noises as a signal; clogged condenser or a non-functioning fan leading to poor heat dissipation; electronic system issues like blown fuses or faulty sensors; or a dirty filter obstructing airflow. For troubleshooting, first check if there are any warning lights on the dashboard, then verify if the compressor is functioning. Remember, timely maintenance can prevent problems before they occur, otherwise it could affect driving safety. Driving without air conditioning in summer is extremely dangerous—it’s best to seek professional repair services and not delay.
Last time I took a long-distance trip in my Edge, the air conditioning suddenly stopped cooling, leaving me sweating profusely. The key reasons could be issues with the refrigeration cycle, such as refrigerant leakage or blocked pipes; compressor damage is also a common culprit; or electrical problems like a stuck relay; dust buildup on the condenser leading to ineffective heat dissipation; if there's no airflow when the AC is on, the filter might be severely clogged. From my experience, first check if the engine compartment fan is running and if the compressor belt is loose. If you're not familiar with electrical details, don't force repairs—head to a 4S shop immediately. This affects cabin comfort, making long drives prone to fatigue and distraction. Regularly cleaning the filter and topping up refrigerant can prevent sudden issues.
