<human>: I'm having problems with my car's air conditioner. What are the signs and how can I fix it?
<bot>: The most common sign of a problem with your car’s air conditioning is an overheating or leaking system, which could cause the interior of the vehicle to become too hot or even smoke. Other symptoms may include difficulty starting the engine, strange noises coming from the compressor, or decreased airflow. If you suspect that there is a problem with your air conditioning system, you should take it to a mechanic for inspection as soon as possible.
