Common Subaru Outback A/C Problems

A number of Subaru Outback A/C problems have been reported by owners.  Most of these problems involved leaking refrigerant or electrical problems, with some reporting issues with the compressor. Below are a description of these problems, what causes them and what can be done.

A/C Refrigerant Leaks

Leaks may occur in multiple locations within the A/C system, which can make them very challenging to identify and fix. However, the majority of leaks will be found near the hose connections, and upon close visual inspection it might even be possible to see the oily substance which is accumulating near them. The best way to solve this problem is by purchasing sealant which is designed specifically for car A/C units and then using it to seal the leak.

Electrical Problems

This issue can be even more challenging to fix than refrigerant leaks, due to the inherent complexity. Once the electrical system malfunctions, so will the A/C. The first thing you will want to do is perform a visual inspection, looking over the wiring. Make note of any wires which are frayed and broken. If such wires are identified, the best solution is to simply mend them with high quality electrical tape. Depending on the extent of the damage, it may be necessary to replace them all together. If none of the wires appear to be damaged, then something else is amiss and you will need to take the car in to a professional who can make a diagnosis.

The Compressor Is Broken

The compressor is tasked with keeping the air conditioner in motion, and is one of its most important components. If something goes wrong with it, refrigerant will not properly circulate inside the system which means no cold air for the driver and passengers. Usually, when a compressor malfunctions, it is the result of not being used for extended period of time. Unlike many machines and components, which wear down from continual use, compressors which are not regularly used will be subject to system shocks when they are finally activated, which can damage them. To avoid this, be sure to run your A/C for at least ten minutes every few weeks during winter, even if its cold outside, as doing this will make it last longer.

Additional Issues To Watch For

Aside from refrigerant leaks, electrical problems and compressor malfunctions, there are other things to watch for. Cooling fans can become faulty, and this will lead to problems with the condenser. When driver’s report that their A/C turns on, but is only emitting hot air, this is usually what causes it. Cooling fans can become cracked due to debris which flows in from the road. Once they become damaged, they will have to be replaced. Since cooling fans are connected to the electrical system, they can also be adversely affected by a fuse that is blown. Unless you have the skill, it is best to have this issue handled by a licensed professional.
