The air-conditioning system of your car is made up of several components that work together to make your drives comfortable at all times. During cold winter days, it keeps you warm and snug while you travel. And during hot summer days, it keeps its cool and cozy inside your car\'s cabin. One important component that makes all these possible is the A/C compressor, which is considered as the heart of the A/C system. Much like the human heart, this component pumps and distributes the life blood of the A/C-the refrigerant. The compressor compresses the refrigerant, circulates it all throughout the A/C, and then sends it to the condensing coils. The compressor works through the help of several pistons and valves that can wear out after years of continued use. When this happens, your drives will surely become less comfortable and you might find it hard to focus on the road. To prevent this from happening, read this brief guide below to help you learn more about A/C compressors.
Symptoms of a Faulty A/C Compressor
Here are some telltales signs that you need to watch out for to find out if you need a replacement compressor.
- A/C failure
This is probably the most obvious symptom if you have a broken compressor in your vehicle. If the air-conditioning stops working, then it\'s time for a thorough check of the entire A/C system, including the compressor.
- No cool air
If you notice that cool air doesn\'t come out of your car\'s A/C, check the compressor for damage right away.
- Clicking noises
If you hear clicking noises coming from beneath the engine, this might be caused by a faulty compressor.
Common Cause of a Faulty A/C Compressor
Since the compressor is made up of moving parts, it requires constant lubrication to function smoothly. However, if there\'s a faulty seal in the system, lubricant will leak out or get contaminated, causing the compressor to malfunction or completely fail if left unchecked. To prevent this from happening, make it a habit to check the seals, ensuring that they\'re properly lubricated.
Diagnosing a Faulty A/C Compressor
Step 1: Start by turning the engine off and leaving your system cool down. After that, locate the compressor, which is usually positioned behind the radiator.
Step 2: Once you\'ve located it, inspect the component for any physical signs of damage by looking for oil, rust, or uneven paint. If all of these symptoms are present, you need to replace the compressor right away.
Step 3: Aside from the compressor, you should also check the drive belt that\'s attached to it and see if it\'s secure and damage-free.
Step 4: Then, check the clutch hub that is sticking out from the compressor to see if it rotates properly. After that, inspect the wires of the A/C compressor and look for any burnt marks.
Step 5: After that, start the engine and turn the A/C on to check if the clutch hub engages. And lastly, check the temperature of the hoses and see if they overheat of have leaks.
