Do you frequently ask yourself, “why is my car air conditioner not blowing cold air?” We can usually observe this situation during summer, where the weather is hot and sunny. However, there are still other explanations behind this phenomenon.
Have you experienced parking in an open area waiting for something or while you were checking your phone? And then it suddenly feels warm inside your car.
Or you and your friends wanted to go on a road trip, but after some time, your air conditioner starts blowing hot air. Isn’t that irritating? It’s irritating that you want to enjoy your car trip, but your air conditioner is not cooperating.
But don’t worry because we’re here to help you fix it by knowing the possible reasons.
Why Is Your Car Air Conditioner Not Blowing Cold Air?
You wouldn’t know how to fix a particular thing if you don’t know what causes it.
Before you bring your car to the repair company, you need to develop a theory of the problem.
So, we have gathered some of the possible explanations to your question, “Why is my car air conditioner not blowing cold air?”
And here they are:
Reason #1. Problems with electrical components
So, your car is composed of many electrical components, such as your battery and compressor.
One of the reasons why your air conditioner blows hot air is there might be a broken fuse. It’s a minor electrical problem, but it would still cause other car components to malfunction.
When an electrical component draws a higher current than it was designed to manage due to a defective device, a blown a fuse happens.
But you can check if this is the problem by following this guide.
Reason #2. Your car is low in freon
Note that there is a refrigerant used in your car. Freon is used to cool the warm air blown by the air conditioner. So, this chemical is responsible for the coldness of the air.
If there are leaks in your car system, especially where the freon passes through, it might cause the air to be not as cold as it should. Your car will be low on freon supply if these leaks are not fixed as soon as possible. And it might result in warmer air circulating in your vehicle.
Reason #3. AC compressor is not well-attached
Some professionals say that when you start to notice a difference in the temperature blown by your AC, the first thing you need to check is the compressor. A loose compressor could also cause leaks.
There are also other valves connected to this component that should be secured tightly. This car part is the most responsible for your air conditioner and the air it blows. It connects the condenser coils and the evaporator, where the refrigerant travels.
The compressor also guarantees that the air is converted to a gas or liquid form, depending on the application. If it’s not attached correctly or is defective, your air conditioner won’t work efficiently.
Reason #4. Stuck blend door actuator
So, it the controls of your car you can adjust the temperature of the air blown by your AC. How is this possible? Well, this blend door is the reason why.
It can swing back and forth in the ventilation system to regulate the temperature based on your settings. If your car does not blow cold air even though you have adjusted the controls, there might a defect in the actuator. Or it’s stuck.
This situation means that it could now swing towards the heater and block the warm air from passing through. You can determine if it’s stuck when it produces a clicking sound. This sound indicates that there is something that blocks the way of the door.
Reason #5. Defective or clogged condenser coils
Clogged debris on the condenser might cause some air conditioner complexities.
The cold air cannot travel through the condenser if there is too much filth or dust. Its function is to convert the freon, the chemical refrigerant, into its liquid state.
If it’s clogged or has some defects, it could not function and won’t alter the chemical. This situation will lead to the AC not blowing enough air or only warm air.
Reason #6. Less functionality
There are some complaints that their car is not blowing cold air when it’s not moving.
Your car is not functioning well when it has stopped moving versus when it’s running.
When your car is in motion, there is greater airflow through the condenser, which is critical for the system’s function.
Reason #7. Overheating car
However, when you’re in traffic or you park under no shade, there’s a chance that you would experience this situation.
We can also say that the components of your car will also overheat, and it would affect your system’s ability to function well. Or the refrigerant might or might not evaporate depending on the degree of temperature.
The freon might evaporate due to the overheating components it passes through.
And that concludes the article, “Why is my air conditioner not blowing cold air?”
Observing the possible defect in your system could give the technician an idea of where to start, and it’s easier for them.
If you are familiar with your car parts, you can fix them on your own.
But it would be best if you ask professionals, especially the company where you bought your car.
