Why won't the Air Conditioner Blow Cold Air?


Why won't the Air Conditioner Blow Cold Air?The air conditioning system in your vehicle is very unique in the way it operates compared to other systems in your car, truck or SUV. Not only does AC play an important role in keeping you comfortable as you drive down the road, especially in the summer, but it can provide safer driving conditions. AC isn't just about comfort! If you notice that your automotive air conditioner is no longer providing you with the cool breeze you crave for your commute home, be sure to reach out ot a professional auto repair shop that can diagnose and repair the issue. Let's dive into a few of the most common reasons for automotive AC failure.


Refrigerant Leak

A common cause of AC failure is a refrigerant leak. AC leaks are very difficult to detect because the refrigerant used in AC systems evaporates on contact with air. To find a leak an ultraviolet fluid must be introduced into the system to determine if there is a leak and where it is. This test will be performed if your AC system experiences low refrigerant pressure.

Electric Fan Failure

If you experience AC issues while idling you need to ensure the electric fan motor is working. Some vehicles have two fans, one for them is for the radiator and the other is for the air conditioning condenser. In hot weather locations it is important to ensure both of these fans work to keep you and your engine comfortable.

General AC Failures

There are a couple of other issues that could cause an AC system to fail. A technician will need to run proper diagnostics to identify the trouble, which may include:

  • Blown Valve
  • Clogged Expansion Valve
  • Broken or Loose Drive Belt
  • Failed Compressor Clutch
