8 Causes of Car Air Conditioning Not Cooling Only Wind

8 Causes of Car Air Conditioning Not Cooling Only Wind

It’s incomplete to drive in a car without using Air Conditioner (AC). The hot air temperature makes AutoFamily turn on the air conditioner so that the atmosphere becomes cooler. However, there are some problems, such as the air conditioner is not cold. What are the causes of the car air conditioner not cold and only blowing air?

Car owners may have experienced the problem of a cooling system that does not feel cold and only blows out air. Some have even experienced an air conditioner that emits hot temperatures so that the space in the cabin feels cramped and uncomfortable. In fact, AutoFamily definitely expects cold air when using the air conditioner, right?

8 Causes of Car Air Conditioning Not Cooling Only Wind

Why doesn’t the car air conditioner get cold, it just comes out of the wind?

The problem with the car air conditioner is not cold usually lies in the engine. In order to find out the specific problem, let’s look at eight causes of this AC not cold.

8 Causes of Car Air Conditioning Not Cooling Only Wind

1. Freon runs out

In order to function, the air conditioner needs freon. If the freon runs out, then you can be sure the air conditioner will not cool and only wind out. Therefore, try checking the AC freon if you don’t feel a cold sensation in the cabin.

If it’s because the freon runs out, you can refill or add it by visiting an official Toyota car repair shop.

2. Dirty condenser

AutoFamily must understand how the condenser works before cleaning it. The condenser is the part of the air conditioner whose job it is to remove the heat released by the compressor.

If this part gets dirty, it will be the cause of the car’s air conditioner not cold, only the wind comes out. To prevent the condenser from getting dirty, AutoFamily must regularly clean the accumulated dirt so it doesn’t cause blockages.

3. Compressor is broken

If, for example, your condenser is clean, but the cooling system still doesn’t feel good, then the cause of the car’s air conditioner not cooling, only the air is blowing out, is the compressor.

The trigger could be due to worn or damaged compressor. Its characteristic is a black sight glass. If this sign appears, it means that the receiver dryer or expansion valve is clogged with dirt.

4. Extra fan is off

The next cause of the AC not cold is the extra fan is dead. If the component located in front of the condenser dies, it will affect the condensation process.

In fact, condensation is a process that makes the temperature drop inside the condenser. If the extra fan does not rotate, the temperature drop will not automatically occur. Finally, the cabin in the car will still feel hot.

​​​5. Car AC system overpressure

Be careful if AutoFamily has just filled compressor oil. Because, filling the compressor oil excessively will make the pressure in the AC freon increase. If the pressure has increased, then the compressor will turn out to be very hot.

The next thing that will happen is the condensation process is hampered. In fact, as discussed earlier, condensation is an important process to lower the temperature. If the process is interrupted, then the car air conditioner will not feel cold.

6. Evaporator clogging

Evaporator clogged with dust or dirt will make the air flow from the blower be obstructed. If the air flow is blocked, the AC circulation will also be disrupted.

Indeed, it is very natural for dust and dirt to enter the evaporator through the suction of the blower that is connected to the component. However, so as not to further reduce your comfort while driving, make sure to regularly clean the AC evaporator.

7. Fan belt broke

The function of the fan belt in the air conditioner is as a distributor of engine rotation to the compressor. If the fan belt breaks or suffers other damage, it can be ascertained that the compressor performance will not be maximized because it does not get engine rotation flow.

If the compressor is not working optimally, the freon will not circulate. As a result, the AutoFamily vehicle’s air conditioner doesn’t feel cold, only wind comes out of it.

​​​8. Thermistor is broken

Thermistor is short for thermo and resistor. This component has the responsibility of sending a signal to the compressor to stop working when the car cabin temperature has reached the temperature according to the settings on the air conditioner.

However, if the thermistor is damaged, no signal will be sent to the compressor. As a result, the compressor will continue to work until the evaporator freezes. If the evaporator is frozen, this condition will cause the car air conditioner to not cool, only the wind comes out.

The cause of the car air conditioner not cold, only the wind blows, it could be for a trivial reason that the freon runs out and needs to be refilled. However, it could also be that the trigger for the car air conditioner is not cold is the damage that occurs to the components in it.

If this is the case, it is better for you to hand over the repair to a trusted professional so that the source of the problem is immediately identified and repairs are made quickly.
