What are the reasons for the Tiguan's air conditioning not cooling?
1 Answers
The reasons for the Tiguan's air conditioning not cooling are as follows: 1. Insufficient or too little refrigerant. The cause of insufficient or too little refrigerant is likely a minor leak in the refrigeration system. 2. Too much refrigerant may also cause the air conditioning not to cool. There are requirements for the proportion of refrigerant volume in the air conditioning system. If the proportion is too high, it can affect heat dissipation. Similarly, if too much engine coolant is added during repairs, it may also reduce the heat dissipation of the refrigeration system. 3. The drive belt of the car's air conditioning compressor is loose. When the compressor works, it may slip, leading to reduced transmission efficiency, lower compressor speed, and decreased delivery of compressed refrigerant, thereby affecting the air conditioning's cooling performance. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it indicates the belt is too tight and should be slightly loosened. 4. In the entire air conditioning system of the car, excessive refrigerant and dirty engine oil in the freezer may also affect the car's air conditioning filter, causing blockage and leading to the air conditioning not cooling. The increased resistance may reduce the flow of refrigerant to the expansion valve, resulting in insufficient cooling capacity.
