5 More Reasons Your BMW AC May Fail When You Need It the Most from Experts in Carrollton
The air conditioning system in your high-end BMW is what makes it very comfortable for you to drive your car in all weather conditions. Mostly the AC system is needed during the hot summer months when the temperature becomes unbearable for driving.
However, the problem starts when you turn on the AC system only to realize that it is not working or fails to provide you with cool air. Here in this article, we will discuss the top reasons behind AC system failure in BMW shared with us by the experts in Carrollton.
Inadequate Refrigerant Level
The refrigerant also known as the coolant is one of the most important fluids in your car that plays a stellar role in not only preventing the engine from overheating but also providing you with cool air for the proper functioning of the air conditioning system.
The refrigerant circulates throughout the system and there are numerous seals and gaskets in place to prevent the refrigerant from leaking out of your car. Now, when the car picks up miles then these seals and gaskets start to wear out and this is when the refrigerant leaks out from a damaged seal or gasket.
The optimal functioning of the air conditioning system in your BMW is completely dependent on the adequate levels of coolant in the vehicle and if there are low levels of refrigerant then the AC system will fail to provide you with cool air when you need it the most & sometimes the refrigerant can also leak out from a damaged hose.
In addition to that, identifying refrigerant leaks in your luxury car is also very difficult and you need to rope in qualified mechanics who can use advanced tools to diagnose the source of the leak & address it accordingly.
Issues with the Compressor
The compressor is one of the most important parts of the air conditioning system of your high-end car. The compressor blows air through the vents of your vehicle and if there is something wrong with the compressor then it will affect the air blowing out from the vents of your car.
Most of the time it is observed that the compressor encounters issues because it is being used sparingly. During the winter months, the AC system is the least used part of your car and this is where the problems begin. Due to lack of usage, the compressor encounters several issues when you suddenly turn it on during the summer months.
There are a lot of internal components in the compressor that are responsible for the efficient functioning of the compressor and at times, it is found that if the clutch on the compressor gets stuck then it can affect the functioning of the compressor adversely.
If the clutch is stuck in the on position then your AC is going to run continuously and if it is stuck in the off position your AC won’t provide you with the cool air.
Electrical Problems
The air conditioning system is part of the electrical system in your car and like the other electrical systems, it is also prone to various issues. Sometimes even minor electrical problems like a failed switch can also cause your AC system to malfunction without any warning.
While problems with the electrical switches can be fixed without any fuss it is the bigger electrical problems like issues with the functioning of the control module that can bother you because not only does it take time to fix these complicated issues but also you have to pay a significant amount of money to get issues like this sorted.
Damaged Cooling Fans
The cooling fan is a vital part of your AC system and provides you with much-needed cool air through the vents into your car’s cabin. Most of the time it is seen that the cooling fan failure is the root cause behind the AC failing to provide you with cool air.
Upon diagnosing you will find that the cooling fan might have stopped working due to a blown fuse or there might be a short-circuit somewhere hampering its functioning.
Malfunctioning Condenser
The condenser in your BMW is responsible for converting the high-pressure vapor refrigerant back into high-pressure liquid. The refrigerant is converted into high-pressure vapor by the compressor and without a properly functioning condenser it cannot be turned back into its liquid form.
Now, a malfunctioning condenser can cause the refrigerant to leak from your vehicle and there are also chances of contaminants blocking the flow of refrigerant through the passages.
Finally
The above-discussed factors are some of the leading reasons behind the air conditioning system in your BMW failing to provide you with cool air when it is most needed. Whenever you observe that something is wrong with your AC system, then take your BMW to a trusted garage where it can be fixed.
