What are some common symptoms of a malfunctioning air conditioning system in a Lexus NX and what are the possible causes of these issues?

Some common symptoms of a malfunctioning air conditioning system in a Lexus NX include weak airflow from the vents, strange noises coming from the vents, and warm or hot air blowing instead of cold air. The cause of these issues can vary, but some possible causes include a refrigerant leak, a problem with the compressor or the compressor clutch, a failed evaporator or condenser, or a problem with the air conditioning control module. In some cases, the problem may be a simple one such as a dirty cabin air filter, low refrigerant level, or a clogged expansion valve. It is important to bring the vehicle to a qualified mechanic for proper diagnosis and repair.
