What causes the Citroen C5 air conditioning not to cool?
1 Answers
The Dongfeng Citroen C5 is equipped with 2.0, 2.3, and 3.0 engines, and after 2014, it has two displacement options: 1.6T and 1.8T. Here are the reasons why the air conditioning may not be cooling: 1. Refrigerant: The refrigerant level is below the required amount. When there is insufficient refrigerant, there isn't enough medium to carry the heat out of the cabin and dissipate it, resulting in poor cooling performance. 2. Mechanical issues: Compressor malfunction: When the compressor is faulty, it cannot compress the gaseous refrigerant into a high-temperature, high-pressure liquid. Condenser poor heat dissipation: If the condenser cannot effectively dissipate heat, the high-temperature liquid refrigerant cannot fully release its heat, leading to poor cooling. Cleaning the dust and blockages between the condenser fins can help. 3. Temperature control switch: Temperature control switch failure: The evaporator may freeze and block the cold air passage, preventing the cold air from circulating. 4. External air circulation: The external air circulation is not closed, allowing outside heat to enter the cabin and affect the interior temperature. 5. Other reasons: Insufficient fan speed, resulting in low airflow. The air mix door is not tightly closed, or the heater core valve is not shut off, allowing hot water to enter the heater core. When the air mix door is not properly closed, heat from the heater core enters the air ducts, affecting the temperature. Overcharging of refrigerant.
