No Cold Air: What Causes Automotive Air Conditioner Failure?


As the Georgia spring and summer approach it's almost mandatory that you have working air conditioning in your car. There is nothing quite like cool, refreshing air blowing in your face during your commute home from a long, hot day at work. If your air conditioner doesn't blow cool then there is a good chance one of the following issues is occurring. To get your AC back on track you will likely need to take your car to an experienced auto repair shop that can handle the heat.

Refrigerant Leak

One of the most common causes of air conditioner failure is a refrigerant leak in the AC system. These leaks are very difficult to detect because the refrigerant used in AC systems evaporates once it comes into contact with outside air. A mechanic will inject a special ultraviolet liquid into the system to determine if there is a leak and find its location, allowing them to repair it. This test will be conducted if it the AC system experiences low refrigerant pressure, which can cause the system to blow warm air or infrequent bursts of cool air.

Broken Fan Motor

If the AC only doesn't work when you're car is idling the electric fan motor may be at fault. Some vehicles have two of these fans, one that is for the air conditioning unit and a second one to help the radiator and cooling system regulate the engine temperature. In places where hot weather is frequent, it is important that both of these fans work properly so that you stay cool, along with your car's engine.

Other reasons your car may need AC repair include a clogged expansion valve, a loose or broken drive belt or even something as simple as a blown fuse in the air conditioning system. Furthermore, a broken or slipping compressor clutch can cause the air conditioner system to blow warm air.
