Why do car ACs stop working?

If your car AC is not working properly, then what could be the reasons behind it? The reasons could be many and understanding them will help you not only in the proper maintenance but will also help you determine when to change your car AC part. You could buy used auto A/C parts from a used auto parts store. 

Common Car AC Problems

The first thing you need to look out for is if your car AC has mold or mildew growing inside. You might have used your AC on for long hours all summer last year and in the winters the AC lay unused, which gave scope for the growth of small microorganisms inside the AC. While getting your car servicing done it is important to do an AC servicing as well.

Your car cooling system problems could be due to the electric system. A short circuit in the system may stop your AC from working properly. When the outside temperature exceeds 45°F, the electric wires of your vehicle may soften and snap causing a short circuit.

A burnt-out fuse has to be replaced as that could be stopping your AC from functioning properly. Any mechanic can replace the faulty fuse.

There could also be an AC refrigeration leak and that could be the reason behind the cooling system not working. This is a common problem and can be solved by a good motor mechanic. This happens when the car meets unexpected accidents causing the leaks.

The condenser can be blocked or broken and stops the refrigerant to contact the hot air to cool. If not addressed immediately, the hot air can damage the condenser.

The fault could be with the compressor and if that is so the refrigerant will fail to circulate inside the AC and will blow hot air in the AC. This especially happens after not using the AC for roughly 2-3 months, particularly after long winters. Make it a habit to switch the AC on for 15-20 minutes at least twice a week even on the cold days.

An overheated engine will make the fan in the radiator ineffective and will stop the condenser from cooling resulting in blowing hot air inside the car.

When the AC air blows into the car the air flaps open then there could be some problem with your actuator. If neglected, the hot air from the outside slows down the air from entering into the car.

Taking the vehicle to a car mechanic will help to understand the exact nature of the problem. If a replacement is required, try Big Mouth Direct your trusted used auto AC parts. Browse https://bigmouthdirect.com/ to get warranted used auto parts for your vehicle.
