AC Not Working in Honda Civic
The AC malfunction in the Honda Civic is not new, and there have been several complaints about it in almost all variants. What’s even worse is that the AC failure in Civic can affect its internal components and affect their efficiency. Hence, you need to address and resolve this issue from the start before it turns into something worse.
So, if you are currently facing this issue and wondering why the AC is not working in your Honda Civic, dive right in. Here are all the possible causes and their quick solutions.
1. Faulty Air Compressor
The first and foremost reason for AC malfunction is the failed compressor, given its primary responsibility is to turn the gas coolants into liquid. When it is not maintained regularly (lubricated enough) or not used for long intervals, it can result in the system eating its particles and accumulating small metals in the AC system. Eventually, it can result in the air conditioner malfunctioning.
Solution
If your air compressor is faulty, the only fix is to replace the entire AC unit. You can get it replaced by your Honda Civic dealer or any professional mechanic. This is because they can provide you with the correct cost estimate and make sure no other part of the system is not affected during installation.
2. Clogged Air Filters
Let us talk about the second most common reason why the AC of the Honda Civic stops working, which is the clogged air filters. The Civic ventilation system has a cabin filter, commonly known as a microfilter, responsible for maintaining the airflow and temperature. Therefore, having dirty filters filled with bugs, grime, microscopic particles, and dirt can result in hindering the working of AC.
Solution
When it comes to the Honda Civic, it is suggested that you change the air filters every 10,000 to 20,000 miles. This is because they get clogged easily and overwork to compensate for the low fuel usage. However, if the problem arises, it is better to get it replaced by any mechanic or yourself.
3. Dirty/ Clogged Condenser
Just like filters, condensers can also turn dirty when not maintained or cleaned properly over time. This is because they are built like filters and can accumulate dirt, bugs, grime, and even microscopic particles, given their mesh-like build, causing the reduction of air passing through them. Hence, eventually, it affects the efficiency of the AC.
Solution
The only way to deal with clogged condensers is to change them or clean them based on the intensity of the damage.
4. Refrigerator Leak
Refrigerator leak is yet another common issue leading to the AC failure in your Honda Civic. The vehicle is built in such a way that it can compensate around 15% of the refrigerator losses annually; however, if it goes below this value, the temperature changes become irregular, and your AC stops working. This is mostly caused by the leak in the system due to the wearing and tearing of its components.
Solution
In this case, you need to check all components thoroughly. See which part is defective, whether it is the seal, the liners, or the condensers. Once identified, replace the part or get it replaced professionally.
5. Evaporation Core Failure
Moreover, a bad evaporator core has also proved to become a leading reason for the AC not working in the Honda Civic. The main responsibility of an evaporation core is to provide cool air and distribute it inside the vehicle. When it gets dirty over time and is not maintained properly, the vehicle cooling process is interrupted, and there is a decrease in air coming out of the evaporator core.
Solution
The correct way to deal with this issue is to brush off the extra dirt and dust particles from time to time. If they are beyond cleaning or repair, it is better to get them replaced by professionals.

6. Faulty Fuse
In addition, if your Honda Civic AC is not working, this can be a result of the faculty fuse in the circuit box. This is an electric failure and has the ability to disturb the working of your AC entirely. The reason why it stops working can be multiple, from dirty air filters to failed circuit configuration or excessive voltage boxes.
Solution
The only way you can resolve this issue is by replacing the blown fuse. If you are not a skilled person, get it replaced by a professional. This is because you need to carefully position it, as it is connected to other components of your vehicle.
7. Blower Motor Failure
A defective blower motor is also why your Honda Civic AC is not working properly. The blower motor in the Civic is responsible for venting out the cool air through the AC. When the motor gets dirty, it can cause clogging on the motor vents, caused by dirt and oil, hindering the air conditioning mechanism.
Solution
Replacing the blower motor can do the job effectively. However, it is better to keep them clean and regularly maintain them from the start.
8. Blend Door Actuator Failure
Honda Civic temperature and air input are controlled directly using its blend door actuator, which means that it regulates the temperature changes in the car. If you hear some loud noises from the blend actuator to the dashboard every time you switch on the AC, this probably means that the actuator has failed. Do consider that sometimes, this noise is only a light tapping on the door.
Solution
To solve this issue, you have to replace the blend door actuator. It does not cost a lot of money, and you can do it yourself if you have a little bit of experience. Or consult a mechanic for a professional replacement.
