If you find your car AC not working one hot summer’s day, you may be in for an uncomfortable ride. As the heat builds up inside your cabin, it can even become dangerous on particularly sweltering days. Let’s take a look at a few different ways in which a car’s air conditioning system might malfunction. If your AC is misbehaving, visit your local Subaru dealer without delay to have it repaired.

Broken Cooling Fans

If no air is blowing out of the AC vents, there may be a mechanical problem with the cooling fans. As the AC generates cool, refrigerated air, the fans should blow this cooled air into the car’s cabin. 

AC fans can sometimes become damaged or clogged from debris flying in from outside the car. A technician should be able to repair a broken or stuck AC fan without too much trouble. 

Electrical Problems

As your AC requires electricity, an AC fault might be due to an electrical issue. An electrical short or blown fuse may be to blame. Alternatively, the wiring might have come loose for the fans, the AC pressure switch, or something else in the system. 

It’s a good idea to check your car’s other electrical accessories. If the stereo, power windows, phone charger, and heated seating are also malfunctioning, the problem might lie with your alternator or battery, rather than the AC. 

Leaking AC Refrigerant 

Refrigerant plays an essential role in keeping your cabin cool. As the refrigerant flows around the system, it is turned from a gaseous state to a liquid state and back again, absorbing heat and generating cool, dry air as it goes. 

Sometimes refrigerant can leak if any of the system’s rubber hoses or seals wear out. A leak will stop your AC from working, and it may also allow moisture into the system, which can cause corrosion and lasting damage to your AC.

Malfunctioning Compressor

The compressor pressurizes the refrigerant before pumping it to the condenser, where the refrigerant transforms from gas to a liquid state. Compressors can occasionally malfunction, which stops the refrigerant from flowing around the system. 

Sometimes the compressor’s clutch becomes stuck in the on or off position. Compressors sometimes run into trouble when unused for months at a time, such as over the colder winter months. 

Faulty Condenser

The condenser plays the key role of cooling the refrigerant, which in turn cools the air inside your cabin. When the condenser in a car’s AC system fails, the air blowing into the cabin may no longer be cold. You’ll need to have a qualified technician find the condenser fault and fix it.
