Air conditioning is one of the most important components and parts of a car, providing comfort and convenience for the driver and passengers alike. A malfunctioning air conditioner can be a source of concern and inconvenience.
Especially with the harsh UAE sun, you need to prepare your car during the summer and avoid air conditioning problems so it can handle the high temperatures.
To detect a car air conditioner failure as soon as it occurs, you'll need to identify the most common car air conditioner failures and their signs. This article will cover the most common car air conditioner failures in detail. Stay tuned.
The most common causes of car air conditioning failure
The structure and composition of an air conditioner contains many parts, and their failure or damage can cause one of the various air conditioner problems, such as:
The problem of a bad air conditioner or a problem related to air flow, such as hot air coming out of the car's air conditioner, is also one of the main reasons. For this reason, we have provided you with the following:
1. No air coming out of the car air conditioner
Air filter problems and signs of damage can interfere with the release of air to ventilate the interior of the car, which means the filter should be cleaned if the problem is impurities, dirt, or even sediment.
However, if cleaning does not work, the filter must be replaced. In addition, leaks and holes in the car air conditioner pipes can cause the car air conditioner to malfunction.
2. Car air conditioning is not cooling
The reasons why your car's air conditioner stops blowing cold air are related to many important factors that must be taken into account when diagnosing a car's air conditioner malfunction if this problem occurs as well.
These factors are primarily the lack of Freon gas or its poor quality. A clogged or damaged air filter in the air conditioner also contributes to this problem. It's also possible that the engine could fail or shut down under strong sunlight.
3. The cold is consistently weak.
- The car's air conditioner sprayer is damaged.
- Relax the air conditioner rollers.
- Radiator fan failure.
- Internal AC fan failure.
- Clogged or damaged air conditioner air filter.
4. The cold increases and decreases.
This air conditioner problem is related to factors related to malfunctions and problems with electrical and other parts of the car, which are not among the main components of the air conditioner and have some of the following factors as well:
- Problems with car fuses and their damage.
- Power outage inside the car.
- Faulty inside the car thermostat.
- Coolant overheating due to sediment buildup.
5. The air conditioner does not turn off when the desired coolness is reached.
Even minor problems can significantly impact your air conditioner's performance. It can also cause your air conditioner to run for extended periods of time. When the temperature drops below the desired level, your air conditioner will stop working. We'll explain the most common reasons why your air conditioner won't shut off:
- The amount of Freon gas is low.
- Weak compressor.
- Thermostat fault.
6. The air conditioner blows cold air at first and then stops.
Car air conditioners can cause problems if they operate in cooling mode for a long period of time. This is due to the freezing of the components and elements of the air conditioner's cooling system. Therefore, the most important factors that cause the cold air to be emitted and then stop are as follows:
- The fluid tank inside the air conditioner is full.
- Run the air conditioner for long periods without stopping.
- There is no harm in cleaning the air conditioner or evacuating the liquid using a vacuum pump.
7. Car air conditioner compressor malfunctions
The air conditioning compressor is one of the most important components of a car's air conditioning system. This is because it regulates the process of producing and circulating air in the air conditioner, then passing it through gas pressure into the car's cabin and then passing it to the components that release air and control the climate in the car.
For this reason, a faulty car air conditioner compressor usually results in poor cooling of the car, so it is recommended to check and inspect these components.
This is because it contributes to a weakening or interruption of the current, or a defect in the compressor capacitor. It can be said that the most common malfunction in a car air conditioner compressor is vibrations between operation and sudden stops, which are often the result of the following effects:
- The amount of gas decreases or increases beyond the normal limit.
- Coolant leak.
- The radiator fan has stopped.
8. An unpleasant smell from the car air conditioner
One of the most common air conditioning problems is unpleasant odors emitted from car air conditioners while driving. These odors can be annoying to both drivers and passengers and interfere with comfort in the car. These odors are often emitted from car air conditioners. Here are the reasons for these odors:
- The presence of dirt in the car's cooling area, which is sometimes called the evaporator.
- Clogged or faulty car air conditioner filter.
- Presence of water standing underground in the car.
- Smoking inside the car while the air conditioning is on.
9. Noises coming from outside the car when the air conditioner is turned on.
Some damage to the car's air conditioner can cause loud and annoying noises to appear inside the car when the air conditioner is turned on. These noises can also indicate the importance of identifying faults in the car's air conditioner and its components, which often include the following:
- Faulty or damaged air conditioner belt.
- Car compressor damage.
- Roman compressor fault.
10. Noises coming from inside the car when the air conditioner is turned on.
These sounds coming from inside the car when the air conditioner is turned on indicate a faulty car air conditioner, which sometimes combines with the following:
- Radiator fan failure.
- Fan corrosion.
- Unscrew the screws on the car's air conditioner.
Car air conditioner turns on and off
The problem of the car's air conditioner being disconnected and constantly running with the air compressor is a real and worrying one.
This is because it is a device used to transfer the mechanical energy absorbed from an electric motor, diesel engine or gasoline engine into the energy acquired and compressed by the air.
The compressor also constantly pushes a certain amount of air into the pressure tank, thus increasing the air pressure in the tank, and it will continue to operate until the pressure in the tank reaches the maximum value.
The compressed air will remain in the tank until it is used, and the energy stored in the compressed air can be used for many applications.
Also, when the compressed air leaves the tank, the pressure gradually decreases, which is accompanied by an increase in the kinetic energy of the air, as the stored potential energy is converted into kinetic energy.
Which can be used in many applications, and when the pressure in the tank drops to the minimum, the air compressor will start working again.
Why is there no air coming out of the air conditioner?
Dust and dirt buildup in the condenser coil limits the ability of the air conditioner to vent cold air. Therefore, it is important to wash and clean the air conditioner regularly to restore it to its original working condition. A malfunction in the heating system:
The thermostat is the main factor in regulating the outside temperature of the room, which is why you should clean the room carefully.
Why is there no hot air coming out of my car air conditioner?
No air is coming out of your car's air conditioner. This is because air filter problems and signs of damage interfere with the release of air to ventilate the car's interior.
This means that the filter should be cleaned if the problem is impurities, dirt, or sediment, but if cleaning does not work, the filter should be replaced, by purchasing a new one.
Does a car compressor work without gas?
A compressor only uses power when it needs it, but if the clutch or pulley of the AC compressor is damaged, the compressor will not work because it will not receive power. It is worth noting that you cannot replace the clutch itself. You must replace the compressor and change the compressor if it stops.
