During the summer, your Honda Civic’s air conditioner (AC) may be your favorite feature. It keeps your car’s temperature cool, enhancing your driving comfort and enjoyment. However, when the air conditioning in your Honda Civic fails, it may transform your driving experience from delightful to miserable.

So, why is your AC Not Working in Honda Civic, and what can you do to fix it?

A blocked condenser, a dirty cabin filter, a refrigerant leak, a damaged blower motor, or a faulty compressor can all cause your Honda Civic’s air conditioner to stop operating. It might potentially be a malfunctioning blend door actuator or an electrical problem that has to be repaired.

There are several components in your vehicle that might contribute to the failure of your Honda Civic’s air conditioning. In this essay, I will go more into the likely reasons and possible solutions. Let’s get started!

Reasons why AC Not Working in Honda Civic and how to fix it

As previously said, the problem with your Civic’s AC not working might be a fault with the air conditioning system’s components. Components of your Civic’s air conditioning system include a compressor, condenser, expansion valve, accumulator, and dryer.

All of your Honda Civic’s air conditioner’s parts and components must be properly functioning for it to perform correctly. So, anytime your air conditioner stops working, it’s important to do a diagnosis to determine which component of the air conditioner has failed. 

However, the following are some of the most typical reasons why your Honda Civic air conditioner isn’t working.

Compressor failure

The compressor is a critical component of your Civic’s air conditioning system. It is the component in charge of cooling your car.

When you don’t turn on the air conditioner in your Civic for an extended period of time, the components might become stuck. This can harm the compressor and need its replacement.

The AC compressor “eats” itself in the worst-case scenario owing to insufficient maintenance or a manufacturing flaw. As a result, metal chips form and spread throughout the Civic’s air conditioning system, resulting in catastrophic failure. In this scenario, just replacing the compressor would not work since the broken chips will also damage the new compressor.

How to Repair

You must replace a faulty compressor in most circumstances; repairing a broken compressor requires completely replacing the chips to prevent them from damaging the new one.

When the air conditioner compressor “eats” itself, the complete system must be replaced. This is because cleaning it does not remove all of the metal chips.

Clogged Cabin Air Filter

The cabin air filter, also known as the pollen filter or microfilter, is an important component of the ventilation system of your Honda Civic.

Internal ventilation diminishes when the filter becomes blocked. The dirt obstructs cooling, heating, and ventilation. The combined effect strains your Civic’s air conditioning system, leading to increased fuel use.

How to Repair

If the filter becomes filthy, you could try cleaning it before replacing it. This can be accomplished using a vacuum cleaner or a pressurized air system. Remove the majority of the visible dirt particles.

This strategy, however, may be inefficient because it does not allow you to reach the deeper levels of the filter. As a result, the filter’s performance may not increase noticeably. As a result, you may have to replace it.

A Condenser That Is Plugged

A clogged condenser might potentially cause your Civic’s air conditioner to fail.

The Honda Civic’s condenser is positioned in the front of the car. It is in charge of dissipating heat from the refrigerant into the surrounding air.

Filth, dirt, and other minute particles that build on the surface and in the mesh of the condenser impair its efficiency. Because less air passes through the mesh, they prevent the condenser from releasing heat. As a result, your car overheats.

How to Repair

You just need to clean the condenser if it’s clogged in your Civic. Removing the front bumper is necessary to gain access to the condenser. You may clean the condenser using a power washer but don’t use too much force to avoid damaging the fins.

Leak Of Refrigerant

A refrigerant leak is a typical reason for your Civic’s AC system failing. This is common as a result of normal wear and tear. It can, however, be caused by poor seals, worn lines, or stone-chipped condensers.

A leaky condenser can cause refrigerant loss and reduce the system’s cooling performance.

The Civic’s air conditioning system is intended to lose up to 15% of its refrigerant every year. Although your Civic will ultimately run out of refrigerant, leaking will cause it to run out sooner which can be the cause of AC Not Working in Honda Civic. When this happens, you’ll just need to replenish it.

How to Repair

Your best bet is to take your automobile to a mechanic. Forming gas will be used to seek for leaks. This will assist in identifying even the smallest leaks and establish whether the leak is caused by a malfunctioning condenser or anything else. In any event, you may need to replace the faulty item.

Blower Motor Failure

A malfunctioning blower motor might possibly be the cause of your Civic’s air conditioning not working. The airflow from the vents diminishes considerably when the blower motor wears out or gets feeble. It also produces strange noises from time to time.

How to Repair

A broken blower motor cannot be fixed; instead, it must be replaced. If the blower motor suddenly stops operating for no obvious reason, look for a blown fuse before replacing it.

A Faulty Blend Door Actuator

The Blend door actuator regulates ventilation and temperature inside your Civic. When there is an issue with the temperature of the air conditioning system, the blend door actuator might be the source of the problem.

When the blend door actuator in your Civic breaks, you will hear a constant clicking sound originating from beneath the dashboard. This sound is frequently present for a few seconds after you switch on the air conditioner or alter the temperature. Changing the temperature can sometimes temporarily diminish the sound.

How to Repair

A faulty mix door actuator may be beyond repair and must be replaced. Because the replacement process is somewhat tough, it is preferable to obtain expert assistance.

Cost To Repair Honda Civic AC

The cost of repairing or replacing each component varies.

Furthermore, the vehicle repair may charge you more than this. Here is a rough estimate of the cost of replacing or repairing components.

Faulty compressor$800-$1200
Dirty condenser$472-$600
Faulty relay$107
Defective cabin air filter$41-$54
Defective blower motor$225-$249
Reduced refrigerant$186-$220
Faulty fuse$96
Bad evaporator core$550-$712
Blend door actuator issue$159-$175
Excessive refrigerant$150-$250

Final Thoughts

To summarize, the Honda Civic AC stops operating for a variety of causes, as I have previously described in this blog

In order to resolve the issue of the AC Not Working in Honda Civic, you may need to repair the broken compressor, clean the filthy condenser, replace the relay, wipe the dirt, replace the blower motor, recharge the refrigerant, replace the defective fuse, clean the evaporator core, replace the blend door actuator, or reduce the topped refrigerant.


Why is my AC not working in my car Honda Civic?

A refrigerant leak, an electrical climate control issue, or a malfunction with the air conditioning compressor are the most typical causes of a Honda Civic AC not functioning. You might not notice a refrigerant leak until the air conditioner stops pumping cold air

Why my Honda AC is not blowing cold air?

It loses its charge: One of the most typical reasons for an air conditioner not working properly is that the refrigerant has to be recharged. You can charge it yourself with a charger kit, but you might feel better at ease taking it to the store for a quick fix.

Why is my AC not working in my Honda?

The most typical causes of an Accord’s aircon not working are a refrigerant leak, electrical problems, or a system failure. The air conditioning in your Honda Accord might be broken for a variety of reasons.

What is the most common cause of car AC not working?

The Refrigerant Level Is Low
One of the most prevalent AC problems is coolant leakage. Because refrigerant flows throughout the system, a leak might occur at any moment.
