Causes of not blowing the AC in the time of acceleration

Causes of not blowing the AC in the time of acceleration

1. Low engine vacuum

A vacuum is used to remove the unwanted substances from the air conditioning system. If there is anything that is not supposed to be there or for some reason, the vacuum is not able to remove the air from the system, the AC can show this type of problem. If you do not evacuate the air and moisture from inside the system it prevents transfer capability through the refrigerant. For that reason, the AC cannot produce cold air and sometimes blow hot air. If your air conditioner stops blowing, first check your vacuum. 

2. Clogged filter

There is a function in some AC that the air conditioner stops when the filter gets clogged. When the filter is covered up by something or the filter cannot remove the hot air from inside then it gets hot and can cause big damage to the whole system. That is why to get rid of the heavy damage, the system turns off. If the system does not have the option to stop blowing air, then it blows hot air.

3. Plugged up cabin air filter

 Plugged up cabin air filter

The cabin air filter is found where the blower motor is located. The air filter helps to clean the air which is inside the car. However, the air sometimes cannot go outside of the car because of the air filter problem. If the air filter is blocked by any substances, then the air cannot be removed from the car or can be removed very slowly through the AC evaporator.

The system becomes very slow and after some time the evaporator will actually freeze. The system has a special key that turns the AC off automatically if anything unusual or unnecessary happens. As a result, when the evaporator is frozen then the switch turns off automatically and your AC stops working. 

4. Condensation of the drain tube

There is a tube from the evaporator which is known as a drain tube. The drain tube is very cold when the evaporator works. In the summer season, the weather outside is hot. In this hot weather, the cold tube temperature increases, and the vapor inside the tube turns into water and starts to accumulate in the tube.

When the AC blows for a long time, then the tube is totally blocked with water and the AC stops blowing. Besides, there is a common problem of leaking the tube. Through the leakage, waterfalls on the carpet of the car and sometimes does damage to the parts under the carpet. 

5. Damaged cooling fan

There are some cooling fans that push the cold air inside the air conditioner and the cold air comes into the cabin of the car through the vents. If the fans are broken or damaged for some reason, the fan will not work. This will also appear as a cause of the stop working of the AC. 

6. Electrical problem

A car has so many electrical connections. It is possible that some of the wire connections are disconnected from the right place. If the connection of the AC gets disconnected, the AC will stop working. Besides, there can be an electrical short in the system. That will show the same result as before.

7. Problem of AC refrigerant 

AC refrigerant is a machine that uses the natural air and makes it cool using the other objects of the conditioner system. Sometimes, that refrigerant does not work properly. At that time air cannot be cooled. For that reason, your AC will not work. 

Steps on how to fix the problem of stopping blowing AC at the time of acceleration
