Honda Civic A/C problems stem from numerous causes, which range from warm air blowing out of the vents to the air conditioning not working at all. Below is a description of these common issues with tips for how they can be resolved.
The Condenser is Clogged
In most Honda models, the condenser is located near the vehicle’s front and is tasked with releasing refrigerant heat within the surrounding air. However, as time passes dirt, bugs and debris can accumulate within its surface and inside its mesh gaps which will inhibit its ability to properly release heat, resulting in poor interior cooling. To fix the issue, you’ll want to clean the condenser which usually requires the vehicle’s front bumper to be removed.
The Compressor Malfunctions
Some drivers have complained of problems with the compressor that led to the A/C not working at all. This device is comprised of moving components that convert gaseous coolant so it becomes liquid. The compressor can malfunction for many reasons, such as its parts becoming stuck or when the compressor consumes itself because of inadequate lubrication. The problem has been encountered in Honda Civics which has about 60,000 miles and many mechanics believe it is actually the result of the compressor clutch. Drivers have been able to resolve the issue by purchasing and installing a replacement compressor.
Your Blend Door Actuator Has Become Faulty
Blend door actuators are responsible for the control of temperature and airflow within the Honda. The most common issue which is encountered with this component is a clicking noise that is emitted from beneath the dashboard. The noise will continue for about three seconds whenever the A/C is activated or the temperature is adjusted, and altering the temperature may stop it temporarily.
Refrigerant Is Leaking
This is probably the most common A/C issue that most Honda Civic owners will encounter at some point. Research shows that about fifteen percent of refrigerant is lost each year as a result of A/C design. This means that drivers who do not have their refrigerant levels inspected and refilled periodically will eventually find themselves in a situation where the levels become so low that the A/C system loses its capacity to cool. The good news is that this is one of the easiest issues to resolve because all you have to do is refill it, which is a straightforward process. However, aside from normal annual refrigerant loss, it could also be the result of a more serious defect, such as a damaged sealing ring, line that has become worn or the condenser has been damaged by a rock.
The Evaporator Is Filthy
This is another key component that must be kept clean. While the air filter is capable of capturing the majority of airborne particles and debris, some of it will inevitably escape and land in the evaporator. While this won’t do much damage in the short term, over the long term the dust will accumulate and eventually block airflow, leading to inadequate cooling. Drivers might also detect a moldy scent.
