The weather in Bora HS (hatchback) is hot, the air conditioner is not cold, the idle speed is unstable, and the air conditioner is frequently started!

Hello: The first and third questions can be summarized as one answer. The vehicle use briefly described above is mainly due to the following reasons of air conditioning system: 1, poor heat dissipation; It is the condenser of the air conditioning system that is blocked, which leads to poor heat dissipation. Therefore, when using the air conditioner, the air conditioner pressure is too high, and the air conditioner under protection and control will stop working, resulting in insufficient refrigeration. 2. Too much refrigerant; This situation will cause the compressor to stop working when the air conditioner compressor is working, because the pressure is too high and the high pressure switch is turned off, so it will also cause the above phenomenon. To sum up, I suggest you go to the repair shop to check the above two points, hoping to bring you help. Secondly, for the use of idle speed, combined with the car condition, I suggest you go to the repair shop to clean the throttle and match the idle speed value of fuel.
