What Causes the Rear Air Conditioning to Stop Blowing Air?
1 Answers
Here are the specific reasons why the rear air conditioning may not be blowing air: 1. Valve malfunction leading to poor opening: When the plastic components of the air outlet valve age or screws come loose, preventing normal opening and closing, it can affect the airflow. You can gently pry open the valve with a tool. 2. Damaged ducts: The air ducts of car air conditioners are made of plastic and can age, crack, or wear due to interference with other components over time. Once the ducts are damaged, air will leak from the damaged areas. It is advisable to visit a 4S shop or repair shop for inspection and replacement. 3. Clogged pipes or air filter: Prolonged use of the car can lead to the accumulation of debris such as leaves, lint, and dust inside the engine, which can block the pipes and reduce the airflow efficiency of the air vents. If the air filter is not replaced for a long time, it can also decrease the airflow efficiency. In such cases, you can disassemble the pipes to clean out the debris and regularly check the condition of the air filter.
