If the compressor doesn't click while ac is on, it could also be low on refrigerant. If you fill it up the proper way and the clutch still doesn't engage (click) then the compressor is most likely bad.
Could also be the pressure switch as well. Could also be the electromagnet. (Unless you check the resistance and it measures between 3-5 ohms. Could be a short in the line like the guy said above and it could also be low on refrigerant. Surprised dude in the video didn’t mention any of these, especially when the pressure switch and being low on Freon is the problem A LOT of the time.
It's either a bad clutch or the compressor is out of freon.. compressor clutches will not engage if they are below a certain amount of freon in the system to protect the unit from completely destroying it due to lack of freon
Im not gonna lie. I was getting a bit nervous with it on the battery like that. When i was young I basicly welded a adjustable wrench to a battery. Got it off with a hammer. Scared the shit out me. Ive also had one blow in my face before so i like to keep batteries safe lol
That is not testing the compressor.. that is testing the CLUTCH of the compressor. The compressor does more things and it could fail in other ways too. The clutch is the first thing to take a look at, but you could easily hear if the clutch is working as it will make a distinctive sound when you press the AC button. What you need to do next is show us how to diagnose a compressor... you guessed it... NOT compressing.
When the clutch gets burned up does the system get contaminated ? I want to know the likelihood of needing to replace other parts like condenser , dessicant bag . drier ? I've got a 15 Ford Fusion 2.5 L Looks bad the clutch material is coming out the front pulley
My Jeep makes a clicking noise all the time whether the car is on or off. The ac goes on and off every 30 secs or so while driving, do you think that’s a bad ac compressor?
Is there any way to check if it has any fluid without the machine? Trying to save some money by changing it out myself and just taking it to a mechanic to fill it up afterwards
I’m 99.9 percent sure that compressor works perfectly fine, why spend 300 dollars on a new compressor when all you have to do is spend about 50 bucks or even less and change out the compressor clutch coil on your existing compressor. It’s just held on by a bolt usually 10mm the clutch drive plate slides out , careful no to lose the shims that come out they’re thin pieces of metal that look like washers , then you’ll see a snap ring holding the pulley in place take the snap ring off then if you’re lucky the pulley should slide out by hand if not you’ll need a 2 or 3 jaw extractor to get it off don’t try using a hammer cause you’ll damage the bearing. Once you got the pulley off you’ll expose the magnetic clutch coil again it’s just held in place with a snap ring get it off and the coil will come right out.
Hello my name is Alice an I have a 2007 Chevy Impala and I have a question, so my car is making a noise someone said it's the compressor but he barley even looked at the car so how does one know it's the compressor? Can u tell just by the sound it's making? An would it still be making that noise if you only needed Freon or to recharge the a/c (my A/C isn't pushing cold air) thank you in advance for any info u can give me regarding this situation 🙃
My compressor was blowing the fuses twice in a month and then now I hear a noise when I turn on the ac...I think it might be the ac compressor...which the mechanic shop replaced last year
Hi. I have a Nissan Xterra that the compressor kicks on when I push the AC button.. but stays on.. doesn’t cycle on and off.. and all while blowing warm air. Any ideas? Thanks!
Thank you young man. I'm impressed with your knowledge and especially the tutorial you presented as if you are Mr. Professor. Thanks again. Great job! 👏
DUH if the clutch is bad you only need to replace the clutch, not the whole compressor! I got quoted $400 from NAPA for a whole new A/C compressor for my Nissan Versa, then realized the clutch was replaceable for $40 from Amazon! It came as a kit with a new electromagnet too, but the old electromagnet was fine so I left it in place behind the A/C pulley.
Best way to test the clutch (magnet) is by checking the resistance. Connect a multimeter to the ground and hot wire. The resistance should be around 3-5 ohms. It can work high or lower than that, but if it does, it’s on its last leg.
From what you typed. It sounds like the clutch is stuck and is engaged no matter what. I obviously can’t see your car, so going based off this the clutch may be bad on the compressor unit. Some shops replaced the clutch part or the entire ac compressor depending on the make and model. As another internet stranger who does not know you personally I would recommend going to a different shop to get another quote or inspection. A lot of times shops will half ass the inspections or won’t do all of the tests to root out the exact issue. So if you feel as if their findings don’t sit well. Listen to your gut and move on to another shop.
My ac blows super cold but it stops working when it wants to then cuts on when it wants too. Ac Air is always cold. All fuses are good, just changed blower actuator. Still nothing. 2016 dodge charger
I had this problem on my 05 g35 and my ac compressor clutch stopped working after the next couple of weeks. Check if your RPM’s jump up and down on idle if they do you most likely will need to replace the air compressor or the ac compressor clutch
@@VQ.Jnthn2300 my 06 g35 has been doing this for like a month now but it’s finally getting bad. i’ll be at a stop light and my rpms would jump up and down but i could never figure out the problem but i think you saved me now cause my air is cold that’s why i never really thought it was the compresser but the clutch make sense as well
Hello, I wanted to ask you if you could help me with my car. I have a 2013 Ford Edge that has a dual system that blows hot on drivers side a cool on passenger side
I have a 1999 Toyota RAV4 and we currently diagnosed that our Air Compressor is making a loud phone-ringing type sound. So far, every time we turn on the car and after a few minutes, the sound begins and would turn off after awhile. I decided to turn on the AC while it'd making sound and it stopped making the sound.
The bearing of the pullley is destroyed. That will heat up to a point it will melt the rubber cover of the bearing, also, the plastic protection of the magnetic coil will melt and could cause short circuit. Try replacing the magnetic clutch pulley bearing asap
I have a 2007 RAV4 and my ac just quit coming on. My son said it made a noise ( no idea ) and the next day nothing. It’s like turning on a stereo that’s not connected to anything, not even a power source. I replaced the resistor and nope. The blower motor is good so I’m at a loss
Did you look to see if the belt broke? Sometimes they use a different belt and they'll freeze up and break just that belt. There's also a switch that signals whether or not there's enough pressure in the AC system lines. Maybe a rock or something hit a line or the condenser and the noise was the refrigerant leaking out. If you want to test that you can either buy some self add refrigerant with a gauge and it will tell you the ammout of pressure in the system. You just want to stay in the green. Or you can unplug the sensor and bridge the wires and if it kicks on you know your switch I bad.
My a/c started blowing hot then cool, not cold anymore. Took it to the dealership they said it’s my compressor, AGAIN, I just got it changed at the dealership 2 years ago like what the heck could be wrong? 🤦🏾♀️ Suddenly it started blowing cold again right by then back cool. Anybody think it’s actually my compressor or could it be something else? 👀
when i press the a/c button in my car the pulley doesn’t move. I unplugged the wire and connected it to the positive side of the battery, after which i hear the clicking sound and the clutch engages. what does this mean and what should i do to fix the problem. Thanks!
I believe you stated that if it engages it could be the fuses. My car is a 2012 Accord V6 and I have swapped the horn relay with the magnet clutch relay but that didn’t do anything. are there any other fuses or relays that I should check or replace too! Thanks again
08 Cobalt 2.2L so I used a recharge kit and it said it was full and the lines where cold but it wasn’t blowing cold air would that be a clogged cabin filter or the compressor ?
When adding oil to an A/C system that was inoperable and now the system freon added without changing the compressor, how much do I add to the system not knowing how much was in the pump.? ( Assuming I know the total oil required)

@@johnnyboyyyyy What are the low and high pressure readings ? What is the ambient temperature ? Are the electric fans operating presuming they are in your system ? Cool down the condenser with spraying water on it , what will the pressures do ?

How would you check if it’s low on refrigerant? The a/c gauges won’t give you an accurate reading if the clutch is not engaged
theres not enough pressure in the system for it to engage. @@michaelhaile401
It could also be a bad clutch
@@michaelhaile401this is my problem now
This isn't about testing the compressor, it's about testing the compressor clutch. Big difference.
If there is no refrigerant in the system the clutch won't engage also
This is actually ChrisFix voice on top …
Yeah, now that you point it out it's obvious.
@@tkorte101its not even close to chrisfix voice 😂
To jump the compressor. Unhook it and run a jump wire in both of the notches/slots, then crank the car. Done
Ground and 12v? Does polarity matter ?
@@davidgomez3737Did you get any answer? Does polarity matter?? I got my cable pulled out of the pins and both of them are black, Idk which is which
The safeguards are now not in play so the pressures aren't controlled.
It's either a bad clutch or the compressor is out of freon.. compressor clutches will not engage if they are below a certain amount of freon in the system to protect the unit from completely destroying it due to lack of freon
U dont need to buy a new one. Check the electromagnetic part inside that pulley. Mostly them the ones burned out. Around 40usd with a set

This video is exactly answered my question.. THANK YOU!! so I'll check the fuses next before throwing away at least 1000 dollars
“Need a new one” ? Need a new compressor or just a clutch if it doesn’t click?
Replacing the clutch is the better way to fix it, it is easy and it costs 1/40 of the price of a new a/c compressor.
Great video
What is the best way to by pass the clutch
Great video 👍
What if the clutch is always engaged
You have a lot to learn
Thank you!
I appreciate your video…Would you happen to know what # fuses & relays I check on a 2007 Chevy Tahoe before I buy a new compressor…??
Should be able to just look up a fuse diagram of your year and modle and can find it that way

damn boss man ninenty nine point nine nine percent? can you post a video?
So question, do you you hook up the wire to a ground or hot prong on the wire plug
So what about if the clutch keeps spinning like it never stops. If so the compressor is bad or not??
What if no power is going to the A/C & it want come on by turning or pressing any A/ C button?
It could also be an open on the ground side if the thermal protector has failed -
Very useful bro

Hi. I have a Nissan Xterra that the compressor kicks on when I push the AC button.. but stays on.. doesn’t cycle on and off.. and all while blowing warm air. Any ideas? Thanks!
Everything is good with the compressor that it will not kick on by the switch what could be the problem all fuses and relays seem to be good
What if air blows but not cold ? And it doesn’t need Freon or bad fuse
Our be like me and have 150psi on the low pressure side while revving (150 was the max on the guage so who knows what it actually was)
I’m at 130-135 psi low side and trying to find any info on it and your the first one - anything yet besides buying a new compressor ?

I constantly have to disconnect and connect my ac compressor for it to turn cold. What could that be?
Good vid
Ok what bout 2004 Honda Accord blowing hot air,vents are hot.please help.thx.
Can the ac compressor make a winding noise when going bad?
The clutch bearing can make a noise when the bearing goes bad if that’s what you mean. Could sound like metal on metal wearing against each other
05 toy avalone 3.5 .no freeon system .I added 12oz of freeon it turn on hot air still gage on red
This is due to activating the AC at a high RPM (for manual cars), the compressor clutch could be damaged in this case.
Best way to test the clutch (magnet) is by checking the resistance. Connect a multimeter to the ground and hot wire. The resistance should be around 3-5 ohms. It can work high or lower than that, but if it does, it’s on its last leg.
What when it turns nonstop?
So I jumped it and filled it with coolant and it works until I remove the jump wire and it won’t engage itself
Check fuses and relay
Thanks
