You can’t afford to get boiled in the heat, can you? The temperature outside is approaching 100 degrees, and your vehicle’s heated engine continues to blow hot air inside. Furthermore, in the middle of nowhere, finding a service center or a technician is usually difficult.
Nothing, believe me, can be a bigger spoiler than this for sabotaging your long-awaited weekend getaway! That is one of the reasons why you should be aware of the factors that may be causing your car’s air conditioning to malfunction. Let’s look at top 5 reasons car AC isn’t cooling.
Mould and Mildew Build Up
Small bacteria might clog the AC vents when we leave the car AC on for an extended period of time. These bacteria can clog the AC vent, causing the cooling system to malfunction. The vents will not work properly no matter how hard you try when this happens. It’s one of the reasons why your car’s air conditioning isn’t working properly.
To avoid such dangers, it’s a good idea to get the car serviced every 5-6 months at the very least. A regular cleaning not only clears the AC duct, but it also prevents common dust particles and other stuffs such as germs and moulds from growing and spreading quickly.
Another unexpected reason for your automobile AC to stop operating is an unwanted short circuit in the electrical unit. In today’s autos, it’s a common occurrence. If you live in an area where the outside temperature often exceeds 45 degrees, the electrical cables may become too hot, causing a short circuit in the inside wiring.
To avoid such difficulty, there is a smart DIY repair task that may be done. Examine the region where the wire was shot, seal it with electricity-resistant tape, and attach the other end to the connecting wire. You can, however, take the automobile to an authorized auto repair shop to get it done. If your auto insurance covers the same, you can sit back and relax while the professionals handle the rest.
You may not be able to diagnose the problem at all times, and if you misplace or dislocate the wire while performing a DIY repair, you risk causing extra damage to the electrical circuit established within. You could have to flood a large sum of money to cover the repair costs.
AC Refrigerant Leak
Another reason your car’s air conditioner isn’t working is refrigerant leakage. The refrigerant, in fact, keeps your cabin cool. In the majority of situations, it has been observed that refrigerant leakage is a common cause of automotive air conditioning failure.
When your car is involved in an unexpected collision, such issues arise. The AC hose leaks from the joints, and it’s difficult to pinpoint exactly where the damage occurred. Leakage in the refrigerant is indicated by the greasy substance that collects around the hose. In a nutshell, your refrigerant has been tampered with, and you must have it repaired.
It’s best if you don’t do it yourself because you won’t know how to deal with the technical issue or what the root reason is for one of these problems. So, before going on a long journey, consider calling an authorized automobile mechanic to fix it.
Another valid reason for your car’s air conditioner not working properly is a faulty condenser. It’s the device in your automobile that keeps the refrigerant cool so it can run through the blower and convert hot air to cool air.
The air in the automobile is blown through the AC vents, and you breathe it in. It can be found directly in front of the grille. If there’s a problem, you can easily locate the grille and diagnose it. If there is a blockage and debris or dust is detected in it, the problem may cause the automobile to overheat. If the condenser is not properly cared for, the warm air that regularly blasts through the vent inside your vehicle may cause harm.
Such problems put a lot of strain on your car’s air conditioner, which might lead to problems with your vehicle’s air cooler. As a result, you must exercise caution!
Taking the car to a competent vehicle repair shop that is authorized to work on similar car models is a good idea.
Damaged or Faulty Compressor
We all know the importance of the compressor in your vehicle’s air conditioning system. It keeps the air conditioner working, but if it breaks down, the refrigerant will not circulate efficiently. Inside the vehicle, it will blow Hot Air. It’s a regular occurrence when you restart your auto air conditioner after a long period of time, say two to three months (especially during the winter months). During the summer, when you need to use the air conditioner, the compressors may fail to perform correctly if they have been idle for a long time.
The compressors are supposed to perform properly if you turn on your vehicle’s air conditioning after a long time, say 15-20 minutes, regardless of the weather outside.
Faulty AC Blower
Another explanation for the inconvenient car AC conditioning is faulty blower vents. It’s one of the reasons why it’s crucial to analyze the blower vents after a 6- to 8-month period.
However, you can perform a self-diagnosis to see how well it works. Feel the speed of airflow in your hands by placing your palms in front of your AC vents. If everything appears to be in order, the air cooler is in great operating order. If you don’t, the blower won’t spin at the proper pace, and you’ll feel it on your hand palm. That’s when you’ll need a mechanic to remedy a problem like this.
Faulty Compressor Belt
To perform properly, the compressor requires a lot of electricity and energy. If the compressor becomes weak or worn down as a result of prolonged use, there is a perceptible shortage of energy in the compressor, resulting in AC failure. Compressor belts that are worn out hinder your automobile from starting. Those compressor belts are responsible for your vehicle’s power and energy functions. When it breaks down, the air conditioner stops working as it should.
It is strongly advised that it should be repaired at an authorized auto repair shop or store and that the compressor belts be replaced as soon as feasible.
The radiator fan will always be useless if the engine is overheated. It will not only prevent the condenser from cooling the vehicle, but it will also use the refrigerant’s utmost efficiency to blow hot air into the vehicle.
Getting professional aid is usually preferable to avoiding such a problem since it will assist your vehicle in avoiding subsequent problems related with the air conditioner equipment installed in your car.
Blocked Cabin Air Filter
If your air conditioner isn’t chilling well enough, it could be a sign of a larger problem. You can make your own diagnosis. Simply open a dashboard holder and remove the cabin filter if it is dusty. If the cabin filter is unclean, it is preventing proper airflow to the cabin. If that’s the case, it’s time to modify it.
You may do it yourself by purchasing a genuine Cabin Filter and replacing an old one, and voila, you’re done. If your problem persists, you should get assistance from a qualified workshop.
Hope the information provided here was helpful? If your car AC isn’t cooling, one of the factors listed above could be the cause. If you cannot fix it yourself, hire the services of a qualified auto mechanic to help you correct the issue.
