During the sweltering summers, driving can be uncomfortable when your air conditioning is not cooling properly. A car’s air conditioning system is complex; however, knowing what makes it stop working can help you optimize your car’s functionality. So, what causes car AC to stop blowing cold air?
- Low Refrigerant Levels: Several factors likely contribute to a car’s low refrigerant levels, with the apparent culprits being a loose connection or a worn hose and a leaking refrigerant. The low refrigerant levels result in your car’s AC blowing warm air. Therefore, instantly you detect a leak, have it inspected by professionals for compulsory repairs.
- Malfunctioning Compressor: The compressor circulates and pressurizes the refrigerant. A faulty compressor can be due to mechanical failure, faulty clutch, or electrical problems. Its failure can bring the entire AC system down, blowing warm air from the vents.
- Wiring or Electrical Issues: Poor quality work affects your auto air conditioning, meaning it can’t maintain the desired cooling and heating temperatures. Consequently, your AC’s electrical and wiring problems can result in warm air blowing from the vents.
- Blocked Cabin Air Filter: It is important to inspect your car’s cabin filter for blockage. It helps you avoid a dirty and clogged air filter, which can negatively affect your car’s performance. The cabin filter helps maintain clean airflow. When clogged and congested, it reduces your auto air conditioning efficiency, resulting in warm air circulating inside the vehicle.
- Failed Fan Motor: The fan motor is located at the front of the car’s motor; it should be in the best working order to maintain proper heating and cooling temperatures. A vehicle’s AC stops blowing cold air when the fan motor is not optimal.
After learning what causes car AC to stop blowing cold air, you can quickly diagnose your auto air conditioning issues beforehand. Call qualified technicians for repair to sort out your car’s air conditioning problems.
