Why is the car air conditioning not cooling after driving through a puddle?

[LeJosiah]

There are several reasons why the car air conditioning may not cool after driving through a puddle, including insufficient refrigerant, internal damage to the air conditioning compressor, or dirty condenser fins. Insufficient refrigerant: If the refrigerant in the air conditioning system has leaked completely, there will be no refrigerant left, causing the air conditioning to stop cooling. Check the pipes, air conditioning compressor, condenser, evaporator, and other components in the air conditioning system for any damage that may have caused the refrigerant to leak. Internal damage to the air conditioning compressor: This can prevent the cooling effect from starting. Typically, a damaged air conditioning compressor will produce abnormal noises. Inspect the air conditioning compressor, and if it is damaged, it will need to be replaced. Dirty condenser fins: If the condenser fins in the air conditioning system are too dirty, it can cause the pressure and temperature in the system to rise too high. To protect the air conditioning system, the compressor stops working, and the air conditioning stops cooling. Use a high-pressure water gun to clean the condenser fins, then dry them with a high-pressure air gun.
