What are the reasons for the Mondeo's air conditioning not cooling?

[JudeLynn]

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.
