What should I do if my AC compressor clutch is not working?
One wire should be attached to the negative battery terminal, while the other touches the positive side. If your electromagnet is good, the compressor clutch will kick on. Remove the positive wire to release the clutch. You can repeat this process several times to ensure the clutch is working as it should.
How much does it cost to replace an AC compressor clutch?
The AC compressor clutch replacement cost will be between $700 and $1000. Labor costs tend to be about $150 to $250, with the new compressor costing $450 to $850.
Why is my a / C compressor not working on my Chevy Silverado?
This condition may be caused by the A/C compressor clutch cycling out early when the low pressure side reaches approximately 380 kPa (55 psi). The fix is to bring the vehicle to the dealer to have the latest software installed into the vehicle. I hope this helps.
What happens if the a / C clutch does not engage?
OK, you’re on the right track. If the system is fully charged (pressure correct), but the A/C compressor clutch does not engage, the fault is electrical. You’re experience as an electrician directed you to first check the basics (fuses), and now it’s time to trace the circuit and determine what we lost (power or ground) and where we lost it.
Why does my AC compressor clutch not engage?
Why AC clutch won’t engage If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways.

How is the compressor clutch relay turned on and off?
In some vehicles the compressor clutch relay is turned on and off by the low pressure switch and the evaporator temperature sensor. In a computer controlled system, the compressor clutch relay is grounded by the computer. If the fuse is good, disconnect the electrical connector from the compressor clutch coil.
Where is the clutch cycling switch on an AC AC?
The clutch cycling switch measures A/C pressure near the evaporator outlet, and is often mounted on the accumulator. If the incorrect pressure is sensed, the switch will open the A/C compressor clutch circuit to prevent operation.
What happens when the clutch on the Air Conditioner breaks?
However, it’s much more common for the clutch to break and make it impossible to turn on the air instead. Without the clutch, the compressor doesn’t receive any power from the engine, so you are left without air conditioning. When the compressor clutch breaks, the bearing inside the compressor can become damaged as well.
What should I do if my air conditioner clutch is spinning?
The clutch allows the compressor pulley to engage or disengage from the motor, ensuring it is only running when it should. If the clutch seizes, normal action cannot continue. Look at the front of the compressor while the air conditioning is running to see if the clutch is spinning.
Why is my air conditioner clutch not working?
If your Air Conditioning compressor isn’t working (the clutch won’t engage) then watch this video. The A/C switch on the dash switches the compressor on, with one exception. If the PCM (powertrain control module) senses low pressure in the low pressure fluid line, it will stop the compressor clutch from engaging to prevent any damage.
What happens when the clutch on an AC compressor breaks?
When the compressor clutch breaks, the bearing inside the compressor can become damaged as well. While it’s not common to see fluid leaking through the front seal because of a failed AC compressor clutch, it’s not unheard of. Look at the compressor to see if there are any signs liquid is leaking out through the front seal.
Why does the clutch not engage in a low pressure car?
If the PCM (powertrain control module) senses low pressure in the low pressure fluid line, it will stop the compressor clutch from engaging to prevent any damage. This is because low pressure = low fluid, and r 134a is also oil/lubricant for the compressor and if you don’t have fluid then you will damage the compressor.
What to do if your a / C compressor won’t engage?
HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…
Why is the pulley on my AC compressor not working?
Check the front side of the clutch to examine its condition. Also, find out whether the clutch and the pulley are spinning. If only the pulley is rotating, the compressor clutch is having an issue, which could be stemming from several sources – a blown fuse, bad clutch oil, low-pressure lockout, or an open wire in the oil.
What happens if your air conditioner clutch is broken?
If the clutch seizes, normal action cannot continue. Look at the front of the compressor while the air conditioning is running to see if the clutch is spinning. With the clutch broken, the compressor could remain activated, making it impossible to turn off the air conditioning.
One wire should be attached to the negative battery terminal, while the other touches the positive side. If your electromagnet is good, the compressor clutch will kick on. Remove the positive wire to release the clutch. You can repeat this process several times to ensure the clutch is working as it should.
Why is my air conditioning not working on my Jeep Liberty?
Dana Dowling/Demand Media The air conditioning system in your Jeep Liberty compresses a refrigerant and blows the resulting cold air into the passenger cabin. When this system is not working properly, it can be because the pressure in the AC lines is too low, or because the compressor has failed.
If the clutch seizes, normal action cannot continue. Look at the front of the compressor while the air conditioning is running to see if the clutch is spinning. With the clutch broken, the compressor could remain activated, making it impossible to turn off the air conditioning.
Where to test the a / C compressor clutch coil?
Use a multi-meter to test . 85 goes to pin # 1 connector 3 at the PCM . The PCM supply’s a ground here to energize the relay if condition’s are right . You could jump pin’s 30 & 87 an if the compressor clutch coil is good ,the compressor clutch will engage .
What happens if your air conditioner compressor gets stuck?
The AC compressor is the most integral part of the air conditioning system which is responsible for pressurizing the refrigerant and its distribution. In case there is any problem with the AC compressor, your car’s AC will not deliver cold air and may even cause the engine to seize if the compressor gets stuck.
Look into This! Engaging the AC compressor clutch at home is not rocket science. There are a couple of ways you can fix the problem to bring back the air conditioning system in order. What is the most common reason for an air conditioning compressor not to engage?
What does it mean when your AC compressor does not spin?
It is an ominous sign when the clutch engages but the compressor does not spin. Changing the compressor clutch could be the only solution in this case. A bad AC compressor clutch needs immediate fixing. A delay can cause serious damage to the air conditioning system and the engine.

Why is the clutch on my Nissan Versa not working?
The clutch failed to activate during the door switch computer test, it did not engage when directly supplied with 12v when jumpered to the battery, and now it measures Infinity measuring across the two pins on the compressor meaning it definitely has a bad coil or something internal. That just sucks.
Why is the AC compressor clutch not engaging?
I have done some preliminary diagnosis on it and could use some advice. The compressor clutch is not engaging no matter how long I watch it on a 70 degree day with AC set to max. I have verified the controls are moving the actuators on the blend door and the blower is changing speed ect…

What does it mean when your clutch is making noise?
Listen for noise with the transmission in gear and the clutch pedal to the floor. Next release the clutch with the transmission in first gear. Noise under this condition indicates a worn release bearing or a worn pilot bearing. To isolate the two, keep the clutch pedal on the floor and shift the transmission into neutral.
Why does my AC make a high pitched noise when I turn it on?
If you turn the AC on and hear a loud noise, it could be a sign that the compressor clutch is failing. Just like the engine, the compressor contains several moving parts. If the clutch or other moving part starts to fail or seize, noises are a common complaint. However, a worn-out or leaking bearing can also create a high-pitched squealing sound.
Why does my Clutch make noise when I release the clutch?
In some cases, the throw out bearing will make noises as you release the clutch. This is commonly caused by the center bearing grinding on the flywheel as it’s moving towards the transmission. If you notice this sound, have a professional mechanic inspect or replace the throw out bearing.
