It becomes even more challenging to deal with the issue since it could also involve other components of the vehicle.

Let us start by having a good view of how the air condition system works, the function of each part, and how it affects the system.

Why Won't My AC Blow Cold Air?

Refrigerant: While this is not part of the system, it cannot work without it. The refrigerant is the lifeline of the air conditioning system. All the components of the system need it for the AC process to be a success.

Refrigerant is found in a gaseous state. In high temperatures and pressure, the refrigerant is in a liquid state. You are therefore advised to stick to the recommended type for your vehicle.

Check Here. Evaporator: This is the only component that is located inside the cabin. The rest of the components are located in the engine bay. The evaporator looks like a small radiator with the same fins and tubes. As the air from the cabin blows through the cold evaporator core, it exchanges heat with the air from outside. That is when cold air is blown from air vents in the cabin. Refrigerant Leakage The main source of AC problems is refrigerant leakage. Bad cooling fans can have a negative effect on cooling down the hot refrigerant that comes from the compressor.

This might be one of the reasons why there is no cold air blowing out of the air vents. This is an essential component of the AC system. We have now learned how the car AC works and the common causes of why car air condition is not blowing cold air.

Here, we shall learn how to fix car AC when it is not blowing cold air. We shall look at the symptoms or what drivers report and complain about and how to solve the issues:. Always check if your compressor supports the type.

After reading this article, you now understand the AC system, how it works, the parts of your car-related to the AC system, and how to diagnose most of the faults in the AC systems. AC faults are very delusive since it involves many parts.You hope to experience a blast of fresh, cool air by flipping on the air conditioner in your vehicle. There are several common things that can keep the AC from blowing cold air into the room, and some are more extreme than others. To find the main reason of why is my car Air conditioner not blowing cold?

It achieves so by reducing the humidity content of the air and, so to speak, decreases the relative humidity. Moisture heats up with humid air. Colder hot climate. The air conditioning system collects the air inside the car, reduces or diminishes the humidity and blasts the warmer air through the air vents.

The main principles in a typical air conditioning system are evaporation, condensation, compression, and expansion. Low coolant will stop the operation of the air conditioner the clutch does not kick in and will allow the compressor work if the voltage in the machine is off. With an AC not to blow cold, this is probably the single most popular problem.

Low refrigerant may come from a variety of factors like leaks and systems that have broken. If your vehicle blows room temperature air instead, it could be a sign of low or empty Freon, in which case you may need to recharge it. The appearance of ice may suggest low Freon levels on the compressor. Normally, this is due to moisture taking the place of Freon. During some point in the air conditioning cycle, a refrigerant leak may occur, and it is often difficult to determine the precise position of the leak.

An oily material can often be seen collecting around this contact, which is possibly the cause of the leak, you or a technician can use a sealant specifically designed for air conditioning units found at most auto parts stores to close the leak.

Of course, another sign of low Freon levels is a visible leak. Freon usually looks like thin grease in liquid state. If you spot any liquid that could be Freon, clean it up and check it again later. That is necessary because the clutch allows the Freon to be pressurized by the compressor.

The clutch fits with Freon-level hearing. A broken condenser can be caused by a puncture from road debris going through the grill of your car and damaging the part, or equipment failure.

If you notice any noticeable punctures in the condenser upon a visual inspection, typically the only way to fix the issue is through replacement. The condenser in the air conditioning unit of your car is meant to re-cool hot refrigerant until it is compressed. If the condenser is blocked from the ground by any form of gravel, the refrigerant cannot be adequately cooled and the engine of the car will continue to work with overheated refrigeration.

This is then moved on to the receiver or dryer until the refrigerant condenses. Another indication that the receiver dryer may have a problem might be the rattling noises. Receiver dryers are chambered and any rattling can be a possible indication of internal disruption or exposure to the chambers during operation.

Fittings may also cause rattling, whether they are loose or hurt. A moldy scent from the AC of the car is a symptom of a weak or faulty receiver dryer.

The receiver dryer is intended to extract moisture from the environment and this can lead to mold or mildew if it cannot do so for some reason.You have bought a car a few years back and you are extremely happy with its performance. It brings a smile to your face whenever you think that it has crossed moremiles without showing any major problem.

But, wait! Suddenly, you encounter this annoying issue of car AC not blowing cold air when idle. You can ignore it for some time but think about the inside getting warmer and warmer when idling on a hot summer day.

Unbearable, right? What are the reasons and how to fix this? The problem occurs at most cars at some point in their lifetime. Poor maintenance of the air conditioning unit is the main culprit for car air conditioner not blowing cold air when idling.

Checking the system from time to time is crucial to keep it in a good condition. The cooling fan in the condenser is the first thing that you should look into while finding out the reason for car air conditioner not blowing cold air when idling.

If the fan is damaged or cannot run with its full force, it cannot cool down the heat coming from the Freon refrigerant through the condenser. When the car runs at a high speed, the condenser does not require the fan for cooling the Freon because of sufficient air passing through it.

But, when the car is not moving, the fan is the only tool for making the Freon cold. Another common reason for car AC not blowing cold air when idle is an overheated engine. The compressor of the AC system moves heat from the radiator to the condenser. The Freon gets used up with the running of the air conditioning. When its level goes lower than the acceptable level, you will face the issue of car air conditioner not blowing cold air when idling.

The compressor can pump the Freon more easily when the car is running at a high speed on the highway but it struggles when the car sits idle. You can do the refill yourself if you know the procedure.

These elements could also bend the cooling system and create the same effect. You have to clean up the condenser fins and other areas to solve this problem. Hopefully this article will be useful for you. If you have any question, leave us a comment below, our auto experts will answer it for you.

So why is your car air conditioning not cold? We see this a lot here at AutoAid. They can be caused by normal wear and tear, or actual damage or malfunctioning parts. Here are six of the most likely causes of your air conditioning not being cold.

Freon is the chemical refrigerant that cools the warm air before it is blown back into your car. The leak can be from a damaged hose, a loose gasket or just a loose connection.

To fix this, we need to find the leaky parts, fix or replace them, and then recharge the system with Freon. Even the best air conditioners can lose a little bit of refrigerant over a number of years, typically so slowly that you never even notice the difference.

But if you do happen to notice that your car air conditioning is not cold, you might just be low on freon. Just bring the car in and we can run some tests. When you heat your car, warm air that flows over your engine goes into your car.

The heart of any air conditioning system is a compressor whose job it is to compress the freon. When the freon later expands, it gets very cold. Air blown across metal filled with cold freon causes the air to cool quickly.

And your compressor might not be working because of low freon levels, an electrical problem, or an overheated engine. If the condenser is blocked by debris or is damaged, the refrigerant will not flow. And something as simple as a blown fuse can cause it to stop working. Freon Leak Freon is the chemical refrigerant that cools the warm air before it is blown back into your car. Your Air Conditioning Needs A Recharging Even the best air conditioners can lose a little bit of refrigerant over a number of years, typically so slowly that you never even notice the difference.

Your Blend Air Door is Stuck When you heat your car, warm air that flows over your engine goes into your car. Tags: Air Conditioning.Imagine driving peacefully on a bright sunny morning listening to your favourite music and enjoying the scenery around you. Absolutely desperate of course!

Any problem in your car that has to do with air conditioning can be very distressing, especially if you live in a hot country. The first thing to check if your car air conditioner does not blow cold air is the condenser fan. If the fan is damaged and does not operate at full power, it will not cool down the heat coming from the refrigerant. Freon is another word for the refrigerant that cools the air. If there is a leak in the system through which the Freon escapes, the air conditioner will not blow cold air out.

Modern car air conditioners are sensitive and need an optimal Freon level to work effectively. One way to check the Freon level is to use the charging machine, which removes all the refrigerant present and inputs the correct amount. If you find that the AC loses Freon very frequently, it is recommended that you check both the hoses and other components.

The air conditioning system must be recharged in order to work effectively. Recharging the AC means filling it with refrigerant so that it can cool down the hot air. Recharging is only a temporary solution if the system has a leak. You can perform the refill at home or have it done by a professional. I recommend taking the unit to a garage, as cars are very sensitive to the correct amount of pressure in the system. Blend Air Door Actuators, also known as HVAC actuators, are responsible for controlling the position of air vents and mixing hot and cold air to achieve the optimum temperature.

If the actuators do not work, you either get cold air only and no hot air, or hot air and no cold air. In such a case, take your vehicle to an automotive specialist who will repair the blend air door. The condenser is the main component of the air conditioning system that provides the cool air. If the condenser is dirty or damaged, the air conditioner will not give out cold air. The filter catches all the dust and impurities that enter the passenger compartment and can, therefore, become clogged over time.

In addition, a clogged cabin air filter also leads to a deterioration in the cooling of the air conditioning system. It is recommended to check and clean the cabin air filter frequently.

The AC recharging procedure can be done at home as well and we will discuss how you can do it. There are some rules in some countries that will make you unavailable to buy the refrigerant as a personal person. In this cases, you have to leave the AC system to a workshop to do the job for you. If you can buy it, you can follow the guide down below.

As already mentioned, refilling the air conditioning system means adding additional refrigerant to the AC system so that it blows cold air out again. The process of refilling the air conditioning system can be done at home and we will discuss how you can do this.

In some countries, there are laws that make it impossible for you to buy the refrigerant as a private person. In these cases, you must get a workshop to fix the problem for you.

If you can buy it, though, you can follow the guide below.
