What Causes Intermittent Car Air Conditioning?
1 Answers
Air Filter Issue: If the cabin air filter is excessively dirty, it can obstruct airflow. The owner can test this by adjusting the fan speed control inside the vehicle. If the airflow is weak and shows little variation, it indicates a clogged air filter affecting cooling performance. Replacing the cabin air filter will resolve this issue. Refrigerant Deficiency Fault: Owners can inspect the sight glass on the air conditioning pipes in the engine compartment. During normal continuous operation of the AC, there should be no bubbles visible in the glass. When the AC stops, brief bubbles may appear, indicating proper refrigerant levels. Otherwise, it suggests abnormal refrigerant quantity.
