Troubleshooting a Faulty Automotive Air Conditioner

Your vehicle's air conditioning system is in place to keep you comfortable on warm days. When it doesn't work, you'll find yourself in a sweat trying to force a breeze from the outside air. However, did you know that an issue with your a/c can actually lead to other issues? This is why getting any air conditioning system problem fixed quickly is important to your vehicle's health, not just your comfort. 

The air conditioning system in your vehicle is very complex and uses many different parts to take in air, filter it, and cool it to the right temperature. Most commonly, an a/c issue can stem from a leak or from a bad compressor. Issues can also be caused by clogged filters, a broken cooling fan, a faulty radiator, or your a/c may just need to be recharged. 

Let's look at how you can troubleshoot your vehicle's air conditioning problem based upon the symptoms you are experiencing. 

If you're A/C is still cool but isn't getting very cold, the issue could be:

  • The cooling fan isn't running
  • The filter is clogged and preventing air from passing through the condenser 
  • The system needs to be recharged to the right pressure settings

If the air is warm, the issue could be:

  • The compressor is faulty
  • There is a voltage problem such as a wiring issue or blown fuse
  • There is a leak somewhere within the system

One thing to note is that almost all air conditioning problems are caused by a Freon or refrigerant leak. The only reason that the refrigerant would be low is due to a leak, so looking for a leak first will usually find the cause of the problem. 

If you suspect an issue with your vehicle's air conditioning system, bring your vehicle into David's Garage for a thorough inspection. We will check the Freon levels, look for leaks, test the condenser and compressor, and also see if the pressure is correct. Once we determine the issue, we can provide you with the services needed to get you driving comfortably again.
