Car air conditioning may not work for the following reasons: 1. The car has not been maintained for a long time: Excessive dust and debris accumulated on the condenser and air filter can lead to poor heat dissipation, thereby affecting cooling. 2. Air conditioning circulation mode: The car usually defaults to the external circulation mode, which brings external high temperatures into the cabin. If the air conditioning is not cold, check if it has been in external circulation mode for a long time. 3. Too much or too little refrigerant: The addition of refrigerant requires a certain proportion. Too much can affect heat dissipation, while too little can impact cooling effectiveness. 4. Clogged filter: If the filter is not cleaned for a long time, accumulated impurities can block the filter, preventing cold air from coming out.
