Air conditioning is an essential feature of a luxurious car and cannot be denied if you are explicitly living in a region with a hot climate.
Although Nissan has always promised to provide high-quality vehicles, specific Nissan Altima AC compressor problems can occur due to various reasons.
These problems might lead to your car’s AC not working correctly, raising the temperature inside the vehicle, and making you sweat.
No one would want that, and thereby, the AC compressor problems should be diagnosed and fixed as soon as possible if you want a comfortable driving experience.
Nissan Altima AC Compressor Problems: Top 05 Problems
The Nissan Altima AC compressor can observe various problems over time.
These problems might vary from model to model and vehicle to vehicle, but most of them are easy to repair.
If you are not willing to go to a mechanic and spend money fixing the AC compressor problems, you don’t have to worry as most of them can be solved by yourself.
On the other hand, if most of the issues are easily repairable, some of the problems might require professional help and might also be pretty expensive.
Some of the leading causes of disturbance in the normal functioning of the AC compressor of Nissan Altima include;
01. Refrigerant Leak
The AC refrigerant leak is one of the most common problems observed in Nissan Altima or any other vehicle.
If the required amount of refrigerant is not reaching the compressor, it will undoubtedly result in a poorly functioning or non-functioning air conditioner system.
However, it is believed that the air conditioner loses around 15% of refrigerant every year due to the vehicle’s design.
The loss of refrigerant will lead to insufficient cooling capacity. You can solve this problem easily by refilling the refrigerant.
But in case you have refilled the refrigerant, and its level has decreased surprisingly again in a short time, there might be a leak.
Any faulty components will cause the refrigerant to escape resulting in a rapid decrease in refrigerant level. The leak is usually a worn line, a defective sealing ring, or a damaged condenser.
02. Clogged condenser
The condenser is present on the front side of the vehicle. It helps the car to release heat from the refrigerant into the air.
As it is lowered onto the front face, it comes in contact with dust, debris, bugs, and other dust particles that can cause clogging of the condenser.
Various particles, dust, and dirt clog up into the gap of the condenser’s mesh.
As the condenser gets clogged, less heat is released that affects the air conditioner’s functionality, and it fails to provide adequate cooling inside the car.
In addition to poor air conditioning due to dirty or clogged condensers, it can also be the case if there is a leak in the condenser.
Leak in the condenser causes refrigerant loss that directly affects the cooling performance of the air conditioner.
03. Faulty or failed compressor
The compressor is the most critical component of an air conditioning system. It is responsible for converting the gaseous coolant gas into a liquid that, in turn, cools down the car’s interior.
If your vehicle’s compressor has problems or is faulty, your car’s air conditioning won’t work correctly.
In most cases, when the compressor breaks down, you will have to replace it with a new one.
If you haven’t used your vehicle or the vehicle’s air conditioner for a long time, the parts will stick and become immovable. In such a case, know that you will have to replace it.
Apart from all the faults that can be fixed, the failure of the compressor is something that cannot be repaired, and you will have to replace the whole air conditioning system.
The loss usually happens due to insufficient lubrication, production error, or metal chip form.
04. Electrical problems
Each electric system has its problems that develop over time. Various electrical issues result in negative results on the compressor of an air conditioning system and can gradually lead to its failure.
Usually, the electrical problems in the compressor lead to various acids building up in the system.
These acids are responsible for damaging the system and might also cause the system to burn out.
The electrical problems typically damage the system’s wiring that results in poor functioning or even the system’s failure.
Therefore, if there is any issue in the wiring of your air conditioning system or the compressor alone, your whole system will shut down completely.
05. Lubricant levels
Lubricant is the significant component essential for the effective functioning of an air conditioning system or its compressor.
If your compressor doesn’t have the required lubricant level, it can lead to severe problems and defects and ultimately compressor failure.
So, it is essential to check the levels of lubricants in the compressor to avoid any inconvenience.
Therefore, if your air conditioning unit is not working correctly or at all, the imbalanced lubricant levels might be a problem.
If the lubricant level decreases below a certain level, the compressor will start to stick, and the parts will have worn out, leading to a complete compressor failure.
Nissan Altima AC Compressor: How does it Work?
Nissan Altima AC compressor is responsible for compressing the refrigerant into a high-pressure gas.
This high-pressure gas is then turned into liquid by the condenser, which releases some heat into the outside air.
The next step is the removal of any remaining water from the refrigerant by the receiver. It also removes all the moisture from the refrigerant.
Then this liquid is passed through the expansion valve. This results in a reduction of the pressure as well as the temperature of the refrigerant.
After that, this refrigerant is then passed through the evaporator. Air passes from one side of the evaporator while the refrigerant passes from the other.
This is how the compressor and air conditioning system of the vehicle works to remove the heat from inside the car and lower the temperature.
Also, the heat is released through the vents, and the refrigerant travels back to the compressor, and the process is repeated.
This is the mechanism and working of your Nissan Altima air conditioner.
Nissan Altima AC Compressor Problems: Detail Solutions with Easy Tips
There are undoubtedly various Nissan Altima AC compressor problems that you might encounter at different times due to other reasons.
Although some of the issues can be solved by yourself, most Ac compressor problems might require professional assistance.
Below are the solutions to the Ac compressor problems mentioned above;
- If there is a refrigerant leak, it is usually detected by filling the forming gas in the system. This is generally done at the mechanic’s workshop.
In case the leak is more significant, it can be detected by using a leak detection spray. Once the leak is localized, it is fixed by replacing the particular component.
- If you have a dirty or clogged condenser, you will indeed have to clean to get the proper functioning system again.
Firstly, you will have to access the condenser by removing the front bumper. Now, use a power washer with a low-pressure setting to clean the condenser.
- A faulty or failed compressor should be replaced with a new one as soon as possible.
- In case of electrical problems, you will have to get the wiring of the air conditioning system checked. Once detected, contact the specific wire or wiring fixed.
- Professionals check the lubricants level, and they adjust the level accordingly. You can avoid lubricant problems with regular air conditioning services.
How to Check Nissan Altima AC Compressor System: the Simplest Method
If your Nissan Altima air conditioning system is not working correctly, various reasons for this poor ac working.
Therefore, you will have to run some tests on your vehicle to check the actual problem so that it can be fixed.
You can check your Nissan Altima AC compressor by following the below-mentioned instructions;
Step 1: Check the pressure
The first thing you need to check is the pressure in the system. If you hear an excellent pressure sound while pressing on the pressure system, it means that the problem is somewhere else.
Step 2: Check the fuse
The next thing you should check is the fuse. After removing the fuse box cover, you will see guidance on all the fuses; check the ac one from there.
You might need to change that fuse. It is pretty inexpensive.
Step 3: Check the power of your compressor
You can check the power of your compressor by using a test light. If the test light lit up when connected to the cable, it means that your compressor is receiving the necessary power to work.
Step 4: Check the pressure switch
Check the pressure switch to detect if your system is receiving enough pressure.
