Why is the car's recirculation button not responding?
1 Answers
The reason the car's recirculation button is not responding is that when the air conditioning's airflow adjustment knob is in the windshield defrost mode, the recirculation will automatically turn off. Below are the pros and cons of recirculation: 1. Pros: Recirculation mainly prevents external dust and harmful gases from entering the car in a timely and effective manner, such as when driving through smoke, dust, areas with strong odors, or in heavy traffic, blocking harmful exhaust emissions from the vehicle ahead. Recirculation can enhance the cooling and heating effects of the air conditioning and provides better insulation. 2. Cons: Prolonged use of recirculation can reduce the air quality inside the car, potentially causing dizziness or discomfort. It is advisable to use recirculation for a while and then switch to fresh air mode for a few minutes to allow fresh air into the car and improve air quality.
