Volvo XC70 AC Not Working – How To Fix

By Max Anthony •  Updated: 02/21/22 •  6 min read

A Volvo car is known for its reliability and dependability. As a car manufacturing brand founded in 1927, Volvo has steadily risen to the top of the automotive industry. Just last year they were reported to have sold nearly 700,000 cars globally. They have been consistently making cars for nearly a century and have earned their reputation as one of the most reliable brands in the world.

One of their best-selling models is the XC70, which has been around since 1996 (though it was known as the V70 back then, before rebranding to XC70 in 2003). The XC70 is liked by Volvo owners because of its reliable and comfortable interior. Additionally, it has a lot of wiggle room, which is perfect for people who want to carry a lot of cargo everywhere, or people with big families.


But when the car isn’t working, things can go downhill fast. One issue that car owners sometimes come across with the XC70 is the AC. When it’s not working, it can be a real hassle for owners to deal with.

What to Do With a Broken Volvo XC70 AC

A broken air conditioner system is an inconvenience that many car owners have to deal with. As an A/C repair specialist, we understand how inconvenient it can be. We know that most people prefer having their cars work properly, and they will do whatever it takes to get their cars fixed and working again.

When it comes to figuring out the reason for a broken XC70 AC, there are a few possibilities:


1) Your refrigerant is leaking

First of all, it is possible that your refrigerant is leaking. It’s not uncommon for cars to develop leaks after being driven around for a while. A refrigerant leak can occur at any point during the air conditioning process, so it is sometimes difficult to pinpoint exactly where the leak is. Most leaks are found near the A/C unit hose connections.


There is also the possibility that some oily substance accumulated around those connections, which is probably the source of the leak. It is often difficult to find those very small leaks. It requires having the whole system filled with forming gas in the workshop. With larger leaks, you may already be able to hear them or you can find them by spraying a leak detection spray on them.


Once you’ve detected where the leaks are, you, or a technician, can put on a sealant (specifically designed for air conditioning units) that you can find at most auto parts stores to close the leak.


2) Your condenser is broken or clogged

Another possible cause of your broken XC70 AC is the condenser. It is a very important part of the system, as it takes in heat from the refrigerant to make cold air for you to use. It also has to remove heat from the hot air that is coming out of your car’s vents. If this part is damaged or broken, then you will not be able to get cold air out of your car’s vents.


If the condenser is blocked by some sort of debris from the road, your vehicle will not be able to cool the refrigerant, and your car’s system will continue to work with an overheated refrigerant. You will quickly find that your A/C unit has only been able to expel hot air.


The condenser is generally found on the front of the car. That means it should be easy to visually see if there is anything blocking the condenser. You should remove whatever is clogging the grill in your vehicle, and it should be able to work well again in no time.


However, if nothing appears to be blocking the condenser, it is possible that it might be broken altogether. Broken condensers are usually caused by an equipment failure, or external damage, such as road debris going through the grill of your car.


If, during a visual inspection, you see a lot of holes and punctures in the condenser, it may be best to replace it completely with a brand new condenser.


3) Your cabin air filter is dirty

If you have been driving your car for a while, and you notice that the cabin air filter is full of dust, dirt, or debris, then this may be the reason why your AC is not working.


Cabin air filters are located in the front of your car’s dashboard. They can usually be seen when you look at your dashboard through the windshield. Cabin air filters trap all kinds of small particles that can get into your system and damage it.


You should clean these filters out on a regular basis, as well as vacuum them out every so often to keep them in good shape. If they get too dirty or clogged up, they can cause a lot of problems with your A/C system, which is why it’s important to take care of them regularly.


4) Your compressor is damaged

A damaged compressor is the last thing you want to deal with when your AC is not working. You should call a Volvo A/C repair specialist as soon as possible if you suspect that your compressor is damaged.


If the compressor does need to be replaced, then it will be best to have it done by a professional. Otherwise, you may risk further damage to your car’s system.


5) Your cooling fans are faulty

When your fans are not properly functioning, you may find that your condenser does not get the proper cooling. As a result, over time, your car may start emitting only hot air. The best way to check if the cooling fan is broken is to look at it.


Cracks in the fan blades caused by debris on the road and a replacement of the fan is the only true way to address these issues. Other common issues that people have with cooling fans include blown fuses and other electrical issues.

In Conclusion

The bottom line is that no matter what is causing your broken XC70 AC, you should never ignore it and let it get worse on its own. If there are any leaks or holes in the system, you should fix them immediately so that your car can continue to function properly.


If there are any blockages in the system, then you should have them removed as soon as possible before they become more serious problems for your car’s air conditioning system.
