7 Reasons For Honda Accords AC Not Working & Their Solutions
Everyone inside the car, including the driver, passengers, your dog, and your golf clubs, will start to feel the heat when the car’s air conditioning isn’t functioning correctly. Which is not a pleasant experience in any sense.
The most frequent factors that prevent your Honda Accord’s air conditioning system from functioning normally include a filthy cabin air filter, a refrigerant leak, a dirty or clogged condenser, a dirty or clogged evaporator, any electrical system issue, etc.
Roles of components in the air conditioning system
Before we dive deep, let’s get acquainted with the components of the AC system. So that the troubleshooting makes more sense. The components are listed below.
Evaporator: This part is responsible for the vehicle’s real “cooling.” The evaporator, which is located just below your dash, cools the air that flows through it while removing humidity from the cabin.
Blower motor: This component circulates the cold air that has been through the evaporator via the vents in your car. For fan speed, it is managed by a central control head (or resistor).
Condenser: The condenser, which is at the front of the radiator, takes the heated refrigerant and cools it while simultaneously lowering pressure. As a result, the refrigerant becomes a liquid that may advance to the following step of the AC system.
Thermal expansion valve: The expansion valve or orifice tube, which is located between the condenser and the evaporator, controls how much refrigerant enters the evaporator, significantly lowering its pressure and temperature.
Compressor: The heart of your air conditioning system. The compressor pressurizes the refrigerant while being driven by the serpentine belt in your car. It is activated and deactivated using the compressor clutch.
Compressor clutch: To engage and disengage the compressor cycle, a specialized electromagnetic clutch known as the compressor clutch is required before the compressor goes on. In order to properly pressurize the refrigerant for use by the condenser, the compressor clutch instructs the compressor when to turn it on and off.
7 Reasons For Honda Accord AC Problems and Their Possible Solutions:
1. Refrigerant leak:
In addition to the regular loss, Honda Accord refrigerant gas escapes are typically caused by component problems. The most frequent culprits include a faulty sealing ring, a worn line, or a condenser that has been harmed by a stone chip.
The Fix:
Larger leaks could already be audible, or you might use a leak-detecting spray to discover them.
Smaller holes need to be located by using a gas detector to check all parts.
Once the leak has been identified, it has to be repaired by changing the appropriate component.
2. Bad compressor:
The biggest damage happens, however, when the AC compressor malfunctions and “eats” itself as a result of inadequate lubrication or a manufacturing fault. Metal chips then develop and are dispersed throughout the Accord’s AC system.
The Fix:
Typically, an AC compressor is regarded as a sealed unit. In other words, the majority of mechanics merely replace compressors rather than fix them. They are not made to be quickly opened and fixed.
Additionally, it is extremely difficult, if not impossible, to find interior components for them.
3. Clogged orifice tube:
Compressor failure is frequently the source of an obstruction in the orifice tube. When this occurs, the tube’s screen filter will include tiny bits of metal and aluminum shrapnel.
The desiccant bag in the accumulator has cracked, releasing desiccant throughout the system, and causing the filter to get clogged with white or brownish particles.
The Fix:
The orifice is in the line immediately before the evaporator in the case of your car’s air conditioning heater. Replace the compressor receiver dryer and hire a specialist to thoroughly clean the system.
4. Moisture in the system:
If moisture gets into the A/C system during maintenance or after any component has been changed, the system will suffer and function poorly.
After charging the system with fresh refrigerant, the A/C system cannot be used to remove moisture.
The Fix:
Due to internal erosion and the potential for the moisture to convert to ice close to the expansion valve, moisture that enters the A/C system will be detrimental to the system and result in poor performance.
To solve this issue, you will unquestionably require expert assistance.
5. Dirty air filter:
Reduced airflow is among the most typical signs that a cabin filter needs to be replaced. Less air will be emitted from the AC system’s vents, indicating a reduced airflow.
The Fix:
It’s crucial to breathe clean, fresh air, particularly on lengthy travels and especially on chilly or wet days when you don’t want to open the windows.
Make sure to get the cabin filter examined or replaced on a regular basis to be on the safe side.
6. Clogged evaporator:
The airflow from the AC vents is choppy and unreliable, and the interior of the car is beginning to smell moldy. These are the two most obvious signs of a blocked evaporator in an Accord.
The Fix:
Cleaning the Accord evaporator is a difficult operation. In most situations, you must remove the entire dashboard before you can access the evaporator. As a result, it is advised that this be done in a workshop setting.
7. Dirt in the blower motor:
Too much dirt caked in the blower fins might throw the spinning cage’s balance off and cause it to wobble. This strains the engine and lowers airflow and cooling effectiveness even further, and may also generate strange sounds from beneath the dashboard.
The Fix:
Remove the blower motor, which is usually found beneath the passenger side dashboard, and verify the cage’s condition. If it is unclean, clean it with a brush.
Can a Faulty AC System Cause the Backup Camera in My Honda Accord to Stop Working?
If you’re experiencing issues with your Honda Accord backup camera, a faulty AC system could be the culprit. The connection between these components may become disrupted, leading to camera malfunctions. To address this problem, it’s recommended to perform honda accord backup camera troubleshooting to identify the root cause and restore your camera’s functionality.
Frequently Asked Questions
Do Honda Accords have AC problems?
A refrigerant leak, an electrical climate control issue, or a malfunction with the air conditioning compressor are the most typical causes of a Honda Accord aircon not functioning.
How much does it cost to fix AC in Honda Accord?
The average cost of a Honda Accord Car AC Repair is $249, which includes $116 for components and $133 for labor. Prices may vary based on where you live.
How do you reset the AC on a Honda Accord?
Hold down the OFF button on the AC controls. At the same time, push the DEFROST button 5 times to cycle the light on and off. Then depress the OFF button.
Why is my Honda AC not cold?
If the air conditioner does not blast cold air through the vents every time you turn it on, it is most likely due to a Freon leak.
Why is my Accord A/C blowing hot air?
If your car’s air conditioning isn’t blowing cold air at all (or attempts but then warms up), you may have a blocked expansion valve, a defective compressor clutch, a leak, or a blown fuse.
How do I make my Accord air conditioning colder?
When you can, park in the shade, and when you’re parked, cover the windshield with a reflective sunshade. Close all the vents but the ones that face you if you are the only one in the vehicle.
Conclusion
There are several reasons why your Honda Accord’s air conditioning may be malfunctioning. When investigating the problem, always begin with the most obvious cause, a low refrigerant level in the system.
If the DIY solutions provided here did not work, or if the system would not come on at all, take your car to a certified mechanic. They have the specialized tools and equipment to precisely diagnose the problem, safely recover and recycle refrigerant, and fix your vehicle’s cooling system to keep you cool while driving.
