Diagnosing Your Vehicle's Air Conditioning Issues

One of the most important components in modern cars, trucks, and SUVs is the air conditioning. On a warm spring or summer day, you press the button for air conditioning and cool air instantly fills your vehicle's interior. Now imagine being stuck in bumper to bumper traffic in Burke, Fairfax, or Annandale, Virginia on your way to work in Washington D.C. It's 100 degrees out, you press the air conditioning button but nothing happens. By the time you arrive at work, you are soaked in sweat and have a sales meeting within the next half hour. It's situations such as these that make us thankful to have certain things. Wiygul Automotive Clinic has put together an article that will help our Northern Virginia customers diagnose a faulty air conditioning unit.

For the most part, your vehicle's air conditioning system is reliable. For recently purchased vehicles, it is rare to have any problems. When it comes to your vehicle's air conditioning, there will be one of two problems: insufficient cool air or no cool air at all. In cases in which there is insufficient cool air, your vehicle may be experiencing one of the following issues:

  • A clogged evaporator
  • Partially clogged filter
  • Clogged condenser
  • Loose drive belt
  • Low refrigerant charge

Repairs to air conditioning systems with partially cool air are usually easier to fix than those with no cool air at all. If you turn on your air conditioning and no cool air is coming from the vents, your vehicle may be experiencing one of the following issues:

  • Leaking A/C lines, hoses or seals
  • A blown fuse
  • Clogged refrigerant
  • Loose or broken drive belt

Wiygul Automotive Clinic recommends that you leave all air conditioning system repairs to a trained professional. In order to properly repair your vehicle's air conditioning system, special equipment will be required. If your air conditioning is working, there are a couple things you can do in the meantime. First, make sure your system is check regularly. Second, make sure you run your air conditioning at least 10 minutes per month.
