What are the reasons for the Polo's air conditioning not cooling?
3 Answers
Here are the reasons why the Polo's air conditioning is not cooling: 1. Lack of refrigerant. 2. Dirty condenser. The following are symptoms indicating the need to add refrigerant: 1. Usage exceeding 5 years. 2. The external unit fan does not blow hot air in summer. 3. Frost formation on the high-pressure pipe (thin pipe) in summer. 4. Ice formation or mist blowing from the internal unit in summer. 5. The thick pipe at the external unit's copper pipe connection does not feel hot to the touch in winter. Below is additional information about car air conditioning: 1. Car air conditioning includes cooling devices, heating devices, and ventilation devices. 2. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
I've encountered many cases of Polo's air conditioning not cooling during car repairs. The main reasons include insufficient or leaking refrigerant, often caused by small holes or loose connections; compressor failures are also common—if the compressor seizes or has internal damage, the system won't function properly. Additionally, a dirty or clogged condenser or a malfunctioning fan can prevent heat dissipation, leading to poor cooling performance. Electrical issues like blown fuses or faulty relays can interrupt current transmission. Moreover, a clogged cabin air filter can obstruct airflow. Long-term neglect of these issues may turn minor problems into major ones, making summer drives unbearable. It's advisable to get a professional inspection at a specialized shop to avoid further complications.
As a Polo owner, I've personally experienced the trouble of the air conditioning not cooling. One time it was due to a refrigerant leak, and after a long search, a slight crack in the pipeline was found; abnormal noise from the compressor can also indicate issues; a broken fan can make the engine compartment very hot, indirectly affecting the AC; replacing a blown fuse is the simplest DIY fix; dusty filters also need regular cleaning. When facing such situations, don't rush to cool down with cold water—first check the basics. If you hear strange noises or the airflow from the vents is weak, it's likely a system problem. Timely repairs can save you more money.
