Why is my Car Air Conditioning not working?

There are several reasons why your Car Air Conditioning might not be working. Here are some of the most common culprits:

Low Refrigerant Level: This is a frequent cause. Your car’s AC needs Refrigerant to function. If there’s a leak in the system, the refrigerant level can drop, making the Air Conditioner blow warm air.

Failing Compressor:  The AC Compressor is the heart of the AC System. It compresses the Refrigerant pumping it through different AC components. The circulation of Refrigerant causes it to change state. The Refrigerant changes from a high temperature vapor to a high temperature liquid. Then it changes to a low temperature liquid. Finally, the Refrigerant changes to a low temperature vapor and returns to the AC Compressor.  This system must be working properly to have cold air at the AC Vents.  A failing compressor can lead to warm air at the vents.

Electrical Issues:  A bad fuse or faulty wiring can be a problem. A faulty control module can also interrupt the power supply to the AC system. This can render the AC System inoperable.

Clogged Cabin Air Filter:  A clogged cabin air filter can restrict the airflow. This makes the AC less effective. A simple fix would be to replace the clogged filter with a new one. Quality Auto Repair Shops will perform a Digital Vehicle Inspection. If during the inspection, the Mechanic finds a clogged filter, The Shop will recommend a new one. Take their recommendation and have it replaced.

Other Issues:  Less frequent causes include problems with other AC Components. The AC Condenser Fan Motor, the Evaporator Core, or the Blower Motor might be faulty.

Diagnosing the exact cause of your car AC malfunction can be tricky. It’s best to take your car to a trusted Auto Repair Shop and have your Mechanic diagnose and repair it.  So, keep cool this summer and have your vehicle’s AC system serviced!
