No cold air: common causes of automotive AC trouble - Strande's Garage

No cold air: common causes of automotive AC troubleThe air conditioning system in your car is very unique in the way it operates compared to other systems in your vehicle. Not only does AC play an important role in keeping you comfortable as you drive down the road, especially in the heat of the summer, but it can allow for safer driving conditions. If you notice that your car's air conditioner is no longer providing you with the cool breeze you desire for your commute, be sure to reach out to a professional auto shop that can diagnose and repair the issue. Let's dive into a few of the most common causes of automotive AC failure.

Refrigerant Leak

A common cause of air conditioning trouble is a refrigerant leak. Automotive AC refrigerant leaks can be very difficult to detect because the refrigerant evaporates on contact with air. To find a leak an ultraviolet fluid must be introduced into the system. This test will be performed after a technician tests your air conditioner for low refrigerant pressure and comes back with a positive diagnosis.

Electric Fan Failure

If you experience AC problems while the vehicle is idling the electric fan motor may not be working. Some autos have two fans, one of them is for the radiator and the other is for the air conditioning condenser. In hot weather it is necessary that both of these fans work to keep you and your engine comfy.

Alternate AC Failures

There are a few other issues that could cause an automotive air conditioning system to fail. A technician will need to run diagnostics to identify the trouble, which could include:

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