What are the reasons for the sudden failure of the Volvo S90 air conditioning to cool?
2 Answers
Volvo S90 air conditioning suddenly not cooling reasons are as follows: Air conditioning compressor belt is too loose: If you turn on the air conditioning in the car and hear a squeaking sound, it is likely that the air conditioning not cooling is caused by the compressor belt being too loose. Insufficient refrigerant: The common refrigerant code is R134A. The consequence of insufficient refrigerant is that it affects the cooling effect of the air conditioning, leading to insufficient cooling. Generally, the refrigerant is in a relatively closed environment. However, after long-term use of the vehicle, the components in the air conditioning system may age and wear out, causing leaks in the refrigerant space, resulting in insufficient refrigerant. Air conditioning filter is too dirty: If the filter is too dirty, not only will it cause more impurities to be inhaled into the car, which is harmful to health, but the dirt will also block the air conditioning filter, so part of the cold air from the air conditioning will be blocked, making it feel like the air conditioning is not cooling.
My Volvo S90's air conditioning suddenly stopped cooling, and there could be several reasons. It might be due to insufficient refrigerant, caused by a leak in the system or a drop in coolant levels due to aging. Compressor issues can also trigger a malfunction—if it fails, it can't compress the refrigerant. Electrical problems, such as a blown fuse or a faulty relay, are common and can usually be checked in the fuse box. A clogged condenser or a non-functioning fan can also lead to poor heat dissipation, causing the AC to fail. Additionally, a malfunctioning temperature control sensor might misread the temperature. If you encounter this issue, it's advisable to first stop and check the AC fuse or feel the AC pipes for any abnormalities, then promptly visit a professional repair shop for diagnosis to avoid affecting your summer driving comfort.
