How To Know If Car Ac Compressor Is Bad – Everyone loves cool weather when driving in hot weather. So, what do you do when your air conditioning system isn’t working well? If you know the symptoms of a bad AC compressor clutch, you can tell if this part is failing or something else is going on.
In this guide, I’ll cover the signs above and show you where the AC compressor clutch is located. I will help you measure it and explain its operation. Finally, before I answer your big questions, you’ll see the average AC compressor replacement cost.
How To Know If Car Ac Compressor Is Bad
If the AC compressor clutch is damaged, the air conditioner may not work or may work intermittently. There may be a loud noise from the compressor or the clutch moving. When this happens, air can become trapped or blocked, and coolant can leak.

Stopping getting cold air from the air conditioner is a big sign. If you don’t feel cool air coming out of the vents, you might think it’s a lack of refrigerant and find that the compressor clutch is the culprit instead.
There are many reasons for the lack of cold air. For this reason, a thorough inspection is required before replacing the part.
Before the AC stops completely, it may work intermittently. Since the compressor clutch is not always engaged, you may get cold air occasionally and sometimes it may fail.
In addition, there is a chance that cold air will escape from the vents a little, but not enough. Either way, you should start investigating the problem before it gets worse.
Symptoms Of A Bad Ac Compressor Clutch + Fixes
When the compressor clutch fails, a strange noise occurs. This noise can give you a headache, starting before other symptoms appear.
The noise is similar to a scream, especially when starting to run. Additionally, this noise may indicate a problem with the bearings.
If the AC compressor clutch is not engaged, the clutch will stop moving. When it’s not engaged, you can’t get cool air out of the system.
If the clutch fails to disengage, the AC will be at a time when it should not be on. If not repaired, it can damage the serpentine belt, so you don’t want to put off getting it repaired.
Ways To Check An Ac Compressor
If the clutch sticks as discussed above, the compressor may or may not be activated. You may not be able to turn the air conditioner on or off even if you make a selection on the control panel.
In most cases, the air conditioning compressor clutch is broken, making it impossible for cold air to flow. However, the opposite cannot be true.
You can also detect a refrigerant leak if the compressor clutch starts to fail. When the clutch doesn’t work properly, the front seal starts to leak.
Car AC refrigerant can leak through small openings. Depending on how bad the leak is, the cooling capacity will be limited.

The compressor clutch may fail to engage for reasons other than simple operation. Also consider these possibilities:
AC compressor comes from a fuse. If the fuse blows, the compressor cannot get the power it needs to run.
In this case, you need to replace the fuse. Make sure the amperage matches what is blown.
Several switches are required to activate the compressor clutch. If there is anything wrong with the switch, it will be unusable.

The most common possibilities include low or high pressure switches, as well as an evaporator temperature sensor. If any of these switches fail, the AC compressor may not start.
The air conditioning system in your car consists of many connectors and wires. A signal is sent through these connections to activate the compressor.
If one of the wires or connectors is cracked or damaged, the signal cannot reach the compressor. The only solution is to repair or replace the damaged one.
For the air conditioner to work properly, the refrigerant needs to be charged to a certain level. When the system is overloaded, the high pressure switch disables the clutch function.

On the other hand, there may be a malfunction without adequate cooling. A low pressure switch is used to de-energize the compressor clutch without sufficient pressure.
When the AC compressor no longer engages, a problem could be the clutch. To check for this problem, you need to pay close attention to your car’s RPM gauge. Follow these instructions:
If you don’t see an increase, there is something wrong with the AC compressor that is preventing it from starting.
You can also use your senses to better identify the compressor clutch. For example, feel if the clutch is engaged. Place your hand on the compressor and feel the vibration. Otherwise, the clutch may not engage.

Additionally, you should listen when the compressor is running. It should make a pleasant sound. When the clutch does not disengage, there may be a clicking noise.
Additionally, check the pulley. When the clutch is engaged, the pulley rotates. If the pulley does not turn, the clutch will not engage.
If it’s not clear what the problem is at this point you can skip the clutch. To do that, you need to follow these steps. However, be sure of what you are doing and keep your hands away from moving parts or you could be seriously injured.
If the solenoid works, the compressor clutch will operate normally. Release the clutch by removing the positive wire. You can run this process a few times if you want to make sure everything is still working, especially if you run into any issues. You should hear engagement sounds each time the clutch engages.
How Long Does An Ac Compressor Last?
Since the clutch is part of the compressor, you can find it in this important part of the air conditioner. The compressor clutch is usually located in front of the compressor. When you turn on the air conditioning system, the clutch should engage and start the compressor.
If you don’t know where the compressor is, you should look at the front side of the engine. It’s a belt-driven accessory, which makes it easy to find. You can also refer to your service manual or owner’s manual for its location.
When you turn on the air conditioning system from your car’s control panel, a signal is sent to the AC switch in the car. This switch allows electricity to travel from the engine to the compressor. The function of the compressor is to compress the freon, so it is used to cool the air. As the pressurized refrigerant travels through the system, it loses the necessary pressure, which is why it returns to the loop system.
The main function of the clutch is to actuate the compressor so that pressure can be generated. Without it, the refrigerator will not pressurize and the system will fail to function.
What Type Of Refrigerant Does My Car Need?
To replace the air conditioning compressor clutch, it is usually best to install a new compressor. A bad clutch will cause the rest of the compressor to fail sooner. Given the cost, it doesn’t make sense to mix it with a clutch.
You can spend anywhere from $650 to $1,400 to replace the AC compressor. Parts cost about $400 to $900, and the rest is labor. On average, it takes two to three hours to replace an AC compressor.
Your repair costs will depend on the type of car you drive and where you have it worked on. Labor costs vary by state, with California having the highest labor costs and Ohio coming in at the lowest. The only difference is the state you live in. You can visit a mechanic in a rural area and pay much less than you would in a busy urban environment.
Of course, the most cost-effective way to replace an AC compressor is to do the job yourself. However, unless you have mechanical expertise, this can be a daunting task. I’m not saying you need to be an expert like me, but you need to know how to work on an air conditioning system, and you need special tools.
How To Tell If A Car Air Conditioning Compressor Is Bad
To replace an AC compressor you need the right AC tools to run and fill the AC system, in which case it may be wise to let a professional do it with the right equipment to do the replacement safely.
No. Few mechanics worry about replacing the AC compressor clutch again. It is generally better to install a new compressor to avoid any future problems due to its age. You are going to spend more, but it will give you peace of mind.
You can drive, but you need to fix it soon. If the clutch seizes, it can damage the serpentine belt or the AC system. When the serpentine belt fails, both the alternator and the water pump
