The Honda Civic AC may stop working when there are internal issues in the air conditioning system. But sometimes it may seem everything is alright, yet the problem is there.
So you must be thinking, why is my Honda Civic AC not working? Several reasons could be behind this issue, including
- A faulty compressor
- Dirty condenser
- Faulty relay
- Defective cabin air filter
- Defective blower motor
- Reduced refrigerant
- Bad evaporator core
- Faulty fuse
This article will discuss the causes in detail, how to fix the problem, and the repair cost. Let’s start it right away!
Why My Honda Civic AC Not Working?
When things go wrong, you will have different issues with the air conditioning system of your Honda Civic. Let’s have a look at the following causes.
Faulty compressor
AC compressor plays a major part in cooling your car. It transfers the refrigerant from gas to liquid. Also, the compressor compresses the refrigerant in the system. And the compressor can get faulty and stuck if you do not use it for a long time.
Poor lubrication can also be a significant reason for a defective compressor. The component won’t work correctly for the lack of lubrication. Moreover, metal sarf can spread throughout the AC system. Consequently, it can affect the replaced compressor too.
So when you replace the compressor, make sure to change the chips as well. Precisely, you need to change the AC system entirely to fix this issue.
Fix: Change the air conditioning system
Dirty condenser
A dirty condenser can be one of the biggest reasons for the AC problem. The condenser delivers heat from the refrigerant to the air.
Consequently, the gas turns into liquid.
So over time, the condenser area can get dirty. The dirty condenser cannot exchange heat. As a result, the AC does not cool the vehicle like before.
Fix: Clean the dirty condenser
Faulty relay
A faulty relay will affect the cooling performance inside your vehicle. The power supply process can’t happen appropriately because of a faulty relay. Moreover, you will see almost no cool air inside the vehicle if there is a faulty AC relay.
Fix: Replace the relay
Defective cabin air filter
A defective cabin air filter can reduce the cooling efficiency in the car. The work of a cabin air filter is that it filters away the toxic gases you exhale into the air inside the vehicle.
Along with that, the air filter provides purified air ensuring health safety.
But the air filter in your car can get dirty over time. This interferes with the ventilation system. As a result, you will face the Honda Civic AC problem.
Fix: Wipe the dirt or mud/replace the air filter
Defective blower motor
A blower motor in a car vents out the cooled air through a fan. But the blower motor can also get dirty over time. The dirt interrupts the venting process of cooled air.
Consequently, when the fan tries to vent out the air, it cannot vent or reduce venting because of the dirt or filth in the blower motor.
Fix: Change the blower motor.
Reduced refrigerant
A refrigerant is a fluid that converts gas to liquid and provides cool air in the vehicle. A refrigerant level can drop if it gets leaked.
Moreover, the refrigerant level can get low over time because of tiny leaks. As a result, low refrigerant cannot provide cool air in the vehicle.
Fix: Recharge the refrigerant.
Faulty fuse
If the AC fuse is blown in the circuit box, it can create issues with the system. It will cause the air conditioning system to stop working entirely. The AC fuse is mostly blown for the dirty air filter. Other reasons could be excessive voltage or fuse box issues.
Fix: Replace the blown fuse.
Bad evaporator core
A bad evaporator can be a leading reason for the Honda Civic AC not working. An evaporator provides cool air inside the vehicle. But the evaporator can go dirty over time. This creates a hazard for the air to spread in the cabin. As a result, the vehicle’s cooling process does not happen properly.
Fix: Clean the evaporator core.
Blend door actuator issue
The blend door actuator controls the air mix door. It regulates the temperature inside the car. When the blend door temperature goes bad, you will see an AC temperature problem. As a sign, you can hear the uneven sound too.
Fix: Replace the blend door actuator.
Excessive refrigerant
If the refrigerant in the vehicle is too topped, it can create issues with the air conditioning system. You will notice warm air is venting from the system.
That’s why the refrigerant should not be too much or too low. The refrigerant should always be at a moderate level.
Fix: Reduce the topped refrigerant.
What Is The Cost To Repair Honda Civic AC?
Repairing or replacing each part’s cost varies from each other.
Additionally, the auto mechanic can charge you more than this. Here is a general cost that you may have to give for replacing or repairing parts –
| Parts | Costing |
| 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 |
Conclusion
To summarise, the Honda Civic AC stops working due to several reasons as discussed above.
And to fix the problem, you may need to change the damaged compressor, clean the dirty condenser, replace the relay, wipe the dirt, change the blower motor, recharge the refrigerant, replace the faulty fuse, clean the evaporator core, replace the blend door actuator or reduce the topped refrigerant.
