Below are the reasons and solutions for the Mondeo's air conditioning not cooling: 1. Lack of refrigerant or overcharging of refrigerant: Use a pressure gauge to check the system's high and low pressure. Normally, the high pressure should be around 13.7 bar, and the low pressure should not be less than 2.5 bar. If the pressure gauge shows very low or no pressure, it is necessary to pressurize the system to check for leaks, then evacuate, add refrigeration oil, and recharge with refrigerant. 2. Refrigerant present, but compressor not working: Generally, the compressor may not work if the external temperature is too low. If the compressor is not working, it could be due to wiring issues, a damaged air conditioning pressure switch, or a faulty electromagnetic clutch. 3. Dirty condenser leading to poor heat dissipation: This affects the air conditioning's cooling performance. The condenser surface can be cleaned with a water jet. 4. Dirty air filter: Replace the dust filter. Regular air conditioning system maintenance includes replacing the filter, using cleaning agents, and dismantling for thorough cleaning.

When I was driving my Mondeo before, the air conditioning suddenly stopped cooling, which was unbearable in the summer heat. Common causes include refrigerant leakage, possibly due to aging pipes or loose connections leading to insufficient pressure; compressor failure is also common, where you hear a humming sound upon startup but no cold air; another possibility is the fan not working, causing poor heat dissipation in the engine compartment; or the air filter being clogged, reducing airflow and cooling efficiency. I’ve experienced this myself—simple checks like seeing if a fuse is blown or inspecting the condenser for dirt can save some money. However, refrigerant leaks require professional tools to diagnose, so don’t tamper with it yourself to avoid safety risks. I recommend going to a repair shop for a comprehensive check. During maintenance, pay attention to cleaning the condenser and regularly replacing the filter to prevent such issues. In short, don’t ignore it—fix it early to avoid travel interruptions or health risks. Remember, a cool drive is a comfortable and safe one.

After driving a Mondeo for a long time, you may encounter air conditioning issues. Poor cooling is mostly due to problems in the refrigeration system. Insufficient refrigerant can be caused by leaks, poor seal at connections, or damaged pipelines. A faulty compressor may produce abnormal noises or fail to respond at all. Fan malfunctions can lead to poor heat dissipation, causing the system to overheat and shut down. Control system failures may result in sensors falsely reporting high temperatures. Clogged filters reduce airflow and affect cooling efficiency, especially when you notice inadequate cooling on highways—opening windows for ventilation can help. You can check the engine compartment fuse box yourself to confirm and replace blown fuses, but for deeper issues, consult a technician to measure with a pressure gauge. For routine maintenance, it's recommended to clean the condenser every season to avoid dust buildup. Addressing issues early saves money and hassle—don’t wait until the compressor fails, which is more costly. If the AC underperforms while driving, it can distract you; get it fixed promptly to ensure safe travel.

My Mondeo's air conditioning not cooling poses a safety risk. Hot weather increases heatstroke risk. First, check simple fixes: a blown fuse in the engine bay fuse box—replacing it might solve the issue; a dirty or clogged cabin air filter—replacing it improves airflow; refrigerant leaks require professional recharge. Faulty compressors or fans often produce unusual noises. Avoid DIY attempts that may damage the system—regular maintenance is key, such as cleaning the condenser and replacing filter elements. If the AC fails, don't push through—safety first, pull over promptly and send to a repair shop for system pressure testing. Ensure electrical circuits function properly to prevent vehicle malfunctions.
