What are the reasons for the Volkswagen Tiguan's air conditioning not cooling?
1 Answers
Insufficient or excessive refrigerant, etc. Below are detailed explanations: Insufficient or too little refrigerant: This is likely caused by minor leaks in the refrigeration system. Excessive refrigerant: The proportion of refrigerant in the air conditioning system has specific requirements. If the proportion is too high, it can affect heat dissipation. Similarly, adding too much engine coolant during repairs may also reduce the heat dissipation capacity of the refrigeration system. Loose air conditioning compressor drive belt: The compressor may slip during operation, leading to reduced transmission efficiency, lower compressor speed, decreased refrigerant compression delivery, and ultimately affecting the car's air conditioning cooling performance.
