Founded on Quality, Integrity & Experience

In Modesto, California, the average high temperature stays above 85 degrees for five months of the year, making it no secret that you need your car's air conditioner working at all times.

What do you do when your air conditioner is no longer blowing cold air? Suffer through it? Drive around with your windows down all summer? Get a whole new AC system installed?

Before you jump to getting car air conditioner repair, go through our handy checklist to see if you can narrow down the problem yourself. This can help the technician find the problem more quickly and could save you some money on repair costs. Keep reading to learn more about what you can do to troubleshoot problems with your vehicle's air conditioner.

How Your Car Air Conditioner Works

Before you can start troubleshooting your car air conditioner, you have to know how it works. This is a quick overview so you know what to look for in order to best inform our technicians of the issues.

An air conditioner uses a refrigerant to remove heat and moisture from the outside air, cooling it before sending it into your car's cabin. To accomplish that, it must be changed from a gas to a liquid and then back to gas through several pressure changes. The compressor and condenser both aid in these processes before the cooled air reaches you.

Troubleshooting Checklist

Some issues can be caught during a car tune-up, so have those done often to avoid some of these issues.

  1. Condenser Blockages
    The condenser is where the refrigerant cools down so it can continue cooling your air. It looks like a radiator. However, the tubes carry the warm refrigerant rather than hot air.
    Sometimes, the condenser becomes blocked by debris in your engine which prevents air from flowing freely over it. This can cause the air conditioner to only blow slightly-cooled air since the refrigerant isn't able to get cold enough to continue cooling the outside air effectively.
    Keep your engine compartment free of leaves or other debris that can clog the condenser.
  2. Clogged Filters in Cabin
    To help keep dirt and other things from getting into your vehicle, there's an air filter that all air has to pass through before going into your cabin. However, if these become clogged, they may prevent the air itself from getting in.
    Check to make sure these filters are clean. If they're dirty, ask our technicians about replacing them to see if that was the issue.
  3. Cooling Fans Not Running
    Sometimes, the problem is that the air isn't going over the condenser at all. If it's not working, you may need to get it replaced.
  4. Wrong System Pressure
    As we mentioned before, the refrigerant in your AC system requires the use of pressure. There are a high-pressure side and a low-pressure side of your air conditioner. If the pressure gets too high or too low on either side, it can prevent the refrigerant from doing what it's supposed to do.
    Our qualified auto mechanic can perform this check for you, make necessary repairs and fill your system with the proper refrigerant to get your AC system cold again for you.
  5. Clutch Engagement
    One of the most problematic parts is the compressor. When your AC is running, it should be fully engaging and moving.
    If the clutch is quickly engaging and then disengaging, the refrigerant may be low. If it's not working at all, it may have shut off because of low-pressure or the clutch is bad.
  6. Blown Fuse
    Another reason the clutch may not be working is a lack of voltage. The compressor runs on electricity so if it's not working, make sure you don't have any blown fuses.
  7. Leaks
    Refrigerant leaks are the most common cause of car air conditioner repair. When there isn't enough refrigerant to cool the air, then you'll get mediocre results or no cool air at all.
    Here are some of the locations a leak can occur:
    • All of the fittings throughout the system
    • The hose manifolds found on the compressor
    • Seals on the pressure switches and on the compressor
    • The Schrader valves
    • The condenser itself

Our technicians are highly qualified to find the leak and make all the necessary repairs.
