I am a new subscriber because I did change the compressor in my 2008 mazda NC miata.I researched yutube and your analysis is so accurate, same issues not cold on idle speed but cooler on driving speed.Changed the compressor and Bingo, very cold now even on idle 30 degrees now its freezing cold using ozone friendly natural gas refrigerant from eBay. And this also the first time I replaced compressor.The last time 10 years ago I was scammed by a Honda dealership here in Lancaster charged me $2300 for the same a.c. job on my honda civic and still did not do it right I have to return 2nd time for them to fix it and come to find out my evaporator is bad.What a bunch of Scammers in the service department.So I tried all DIY job on all my cars since then.
The revving the engine info was GOLDEN. Thanks bro.
That’s exactly what’s going on with mine!!! Thanks. It slowly got worse over a period of a few weeks now nothing.
Very helpful. Had the same issue--temp fluctuating up and down as i drove and/or idled at lights. This was very helpful to understand the issue and confirm the diagnosis from the shop. Thank you!
The first video I watched was this one…immediately subscribed….Thank You
Reeds in the comp are allowing the high psi hot gas to return to the low side giving a high suction psi.
I knew mine was bad when it locked up and made one hell of a screeching sound and stalled the engine
Hope you got back on the road quick! Mine makes an awful noise so I don’t use it, I don’t need it freezing up and break my serpentine belt. 😬
You turn it off and the engine unstalls.
Good way to tell
@@namastesunshinecindy5566 you should replace it I paid under 150 to save a hellavaproblem
@@W81Researcher genius 😆
Would any body else have like a burning smell???
Very helpful. This is the exact problem my compressor is doing. When foot on the gas the compressor starts to do its job. Thank you for this video.
Sometimes a simple thing as compressor connecter can stop a compressor , I told mechanic can you check connecter, he said it is broken and fixed it and it worked
Mine seized up on my 2013 F150 5.0 finally. Snapped the belt in the process. Luckily that belt only runs the ac system pulleys and the other belt runs the water pump and alternator so I can still drive it.
@Nimble KIllaI'm still driving mine just fine. I removed the a/c belt completely and just keep all my windows down when I'm driving for cooler air. Lol. Not wanting to spend $300+ for a new compressor kit at the moment.
I'm sitting in my car thinking my compressor was bad so I looked it up here on youtube and I saw you vid and it looked like you were going to get straight to the point which you did and actually showed my exactly what I was just doing parked. My baby has the same symptoms.
So I think you for sharing that.

That’s exactly my problem. Standing still blows hot air but driving is ok. Could blow colder I’m sure. I suspected it’s the compressor and it seems I guessed right by your explanation.
I just received a recall notice and warranty extension from Honda re: AC compressor shaft seal leak. Did you get a notice as well? It is dated June 2023. Covers 2016-2021 Civics and 2017-2022 CRVs for original owner and any subsequent owners.
Is increasing strain on the engine(almost to the point it stalls)when the compressor kicks on a sign it's going bad. For some reason my car automatically kicks on the compressor(even when it's cold and the heat is on) when I turn on my front defroster,so it's not even running the ac,but still putting a noticeable amount of strain on the motor. I plan on keeping the car forever as it's 27yrs old and the model is becoming a more and more scarce,and it's something that's always happened so idk if it's normal,but it's more noticeable than on any other car I've ever had
Great video. Really liked the graphics of the compressor and of the AC tool. Thanks
So if the temperature doesn't fluctuate the compressor is still ok?
What about when the ac is running cold? But there's smoke coming from under the hood?
Hi can a bad ac compressor cause rough idle, misfires and poor engine performance also??
To my understanding, yes. Just ran into a misfire when the ac was running. Turned the car and ac off and let it sit for a couple minutes before going home for an hour drive. Ac wasn't running and we didn't run into any issues on the way home, check engine light even turned off when I started the car with no AC on
My car do the same thing! It blows out good air, but every time I use my air my engine pulls bad. @DatBoiT24
Now my AC turns on and listening fan turns on has a right amount of refrigerant but I still get warm air any ideas
What was it? Thermostat?
I also get a strange sound when i initially turn the ac on alongside not blowing as cold on idle. Cheers think you figured it out for me
Good Day Sir, every time I expose the car in the Sun for longer period of time, and decide to drive. The aircon cause a strange sound and not releasing the cold. What's the cause of that problem?
My car sounds like the belt is bad or ac compressor is going bad! Its cool and stays cool just loud noise under hood like a bad belt or compressor going out
Joe Gandarilla ,if its the compressor you might stretch its life with an ounce or 2of the proper pag oil.
Do I need to replace the condenseur if I replace the ac compressor ?
Would this have any reason as to why my car won’t start after I replace the AC?
I pulled a vacuum for 30min, added the recommended freon now it is whining badly and it actually slows down the car or robbed a lot of power when the compressor kicks in
Thank you ever so much for making and uploading this short yet very informative video loaded with just the right information ℹ needed right now.
Thank you my Question has been answered time for a compressor
That is a killer diagram of the AC compressor
indEEd it is
Ac and heat only work on high. What's the problem?
brother you helped me a lot! I was wondering why on regular idle my ac was sort of cutting off and only blew warm air, but when i'm cruising at 60/70 mph it would feel like ice just incredible. Thanks so much for this basic simple info. I'm off too change my AC compressor.
Did the new fix the problem?
My 2010 Camry has a knocking/rattling sound when compressor is on. Sound goes away when just the blower on. Ac is ice cold.
I was told compressor and ridiculous price, but after a few videos I'm wondering if it is just a pulley or clutch assembly? Thoughts?
How will it differ from low refrigerant? it should produce similar situation in either case.
Loss of blower speed but still cool air comes out
could a bad belt causing belt slippage cause this same syptoms as well?
That is my question aswell??
How do you know when to change just the compressor or the whole system? I've been told and seen on YT once the compressor goes bad fine metal particulate contaminates the system an will continue to blow through the evaporator, condenser, etc and will quickly blow back into the compressor and ruin the new one.
Can it overheat the car?
I need a little help with my 2006 Honda civic. Got the car used with no AC. I tried fixing it by replacing ac condenser, evaporator coil, and receiver dryer. I didn't replace the ac compressor. Charged it up, it was somewhat cold but not freezing cold. This was 3 years ago. Now the AC is blowing cool but not cold air. I thought maybe there was a leak but there's pressure in the lines. I added a little more freon, it got a little cold at that time and next day, it was blowing cool air only. So maybe i got a weak or bad ac compressor, what do you think? Everything else there was replaced not too long ago. I think I'll replace the ac compressor because i can't figure out what else could be wrong with it. The AC compressor clutch is fine.
Thanks. Exactly what my2012 Tucson is doing. I sweat at stop lights and then is cools off a little when I drive to the next stop light.
Is it cold at stoplights? Or no cold at all?
@@aldoboquiren5304 no cold at all.
Our 2012 Tucson did that a few days ago, and now it's rattling badly. Whelp... time for a new compressor, condensor and receiver Drier, seals and expansion valve. (if it's making that much noise, it's likely lost some bits of parts in the cooling system, so I need to flush it out, and there's no way I can flush that condensor well enough to avoid re-contaminating the new compressor. Take a look at this video for some tips on diagnosing. ua-cam.com/video/BXTZURC5iQ0/v-deo.html If you do decide it's your compressor, you can look at this video which is EXCELLENT. ua-cam.com/video/cn49NjwjfYQ/v-deo.html . It doesn't show any flushing of the system. I bought my parts at Buy Auto Parts. They had a 2 yr warranty on the compressor, and their condensor was cheapest by far.
@@jum5238 I bought a compressor, expansion valve and filter on amazon and installed them last weekend. Had a mechanic recover the R134a and then I Loaned the pump and manifold kit from Autozone. It's running great now. Now that you mention it, there were times if I started my car with the AC on, it would rattle badly.
My car shakes when I trun on my ac does that mean I have to replace it?????
What if you have low Freon? Will it have the same symptoms?
I just installed a new air Conditioning system on a 2007 trailblazer I bought the kit from Napa it came with a new compressor and a little aluminum tank I forgot what it was called But we installed it on the car it came pre-charged with oil in the compressor and we actually dumped it out and added oil to it but the air worked amazing and I mean amazing would put frost on your windows for about two months and then three days ago we pull up to a red light and within 10 seconds the air went from freezing cold to hot. So I pop the hood and the compressor was not spinning. We checked the low pressure valve and it is working properly and the Freon levels are good. The only way the compressor will come back on is if you shut the car off and let it cool off for about an hour and when you start it back the compressor will run. And if you jump the relay with a wire the compressor will kick on and as soon as it kicks on you can take the wire out and put the relay back in and it will run for about 15 to 20 minutes again, But on a normal morning when you start the car the compressor will run for about 30 minutes sitting in the driveway in about 15 minutes if you’re driving it and then it will shut off and not come back on unless the car is cooled off. every mechanic shop I have spoke to has no clue why this does that. Do you think the new compressor is bad?
Mine is turning but blowing hot air, also pulley is grinding. Never had one do that.
my a/c blows in high till I get on freeway than blows alot slower yet still cold. Is this a compressor or electrical issues,?
See my thing is, my a/c works fine. But when I do have it on there’s a whistle that repeatedly goes in and out consistently. Do y’all know what it can be? Maybe a belt tension or serpentine?
My car hose was leaking I plugged all the holes up but I see the Freeon come out near the fan area as soon as the fan starts is that a compressor or a bad fan
How often do you add oil to ac compressor ?
If the pressure switch is faulty would the out cover plate still spin with the pully whether the air-con is on or off as I can't hear the compress clutch clicking?
U solved my problem that i was working on a suzuki grand vitara
Does this work the same way with heat and would a bad compressor cause over heating
How to tell if your AC compressor solenoid valve is bad?
Hey thanks for the info working on my car notice the clutch is short cycling the freon is good pressure switch is good but the clutch keep cutting off and on to soon could it be the coil is going bad
This condition AC compressor able to self repair change small parts instead of change new compressor? Please advise..
Did you get the warranty extension from Honda on this issue. Ours was just received in the mail today. Covers 2016-2021 Civics and 2017-2022 CRVs. Original and / or subsequent owners. They will also reimburse for any repairs related to this as long as it meets the reimbursement requirements.
Thanks that really answered my question fast!
Great info simple diagnosis
Thx just what I was looking for golden info thanks a lot 😊😊
wait so how would you know the difference between a stuck expansion valve issue vs a bad compressor. in essence I would assume both would show on the ac gauge that the low pressure is too high and that the high pressure is too low (I might be wrong). but it that were the case how would you know which one is the issue? there's a big difference money wise to replace an expansion valve vs replacing an ac compressor.
also I've heard that when you replace an AC compressor you have to replace the condenser, dryer and possibly the expansion valve. is this true or do u perform an AC flush to rid the system of metallic particles. I have a Hyundai Sonata 2013.
Your air conditioning normally gets alttle colder if you're at a higher RPM .. Just like at a higher RPM your voltage goes up...My air conditioning is always cold..
I just added freon to my vehicle its cold and staying cold but loud noises around fan area and vibration any suggestions or ideas of the cause?
The problem am having with my ac is. Sometimes it get cold and get hot by it self and get cold and hot again. Is not stable at all. Just get hot and cold while driven
did you fix it?
That sounds like the orfice tube or expansion valve
Well this sucks. I've NEVER used my ac in my 2016 colorado because I worked overnights never hot at night. Now I work during the day and ac would work once in a blue but stopped entirely for at least a year about a month ago it was working again for 2 days straight till I remote started the car with a quarter tank left... hot air immediately doesn't work now. Ac doesn't even kick on at all just blows air in if I use ac with air from outside its warm opposed to no ac and letting air blow in feels cool.
Amazing video, thanks.
So weird! my 2016 Off Road, 4x4, all of a sudden just shut off. (green ac light went off and stays off). When I push the AC button on, I can hear it run then it shuts off, green ac light goes off. I checked the fuse and the replay, they are working properly. I had a friend come over and he said the compressor is running which is good news, however, he then assumed the refrigerant its empty so he was going to add freon but, his gage says the freon in full. That is where we are confused. Also its the 1234y NOT the usual 123A. Any insights? I want to sell this truck but I need to get this fixed first. We live in Florida. We do NOT have the $$ to have it serviced or even diagnosed at a local toyota dealership, they are way expensive. Just installed new air cabin filter, it was atrociously bad, but that hasn't fixed it at all. ???Help??? MIGHT be a bad pressure switch>?? Praying mine if NOT behind the firewall.....ugh!
My ac got hissing sound,no cold air....i check the compresor ok.. whats the common prob?
Mine never gets cold. It blows well but only warm air. The gauge says I have coolant. Should I change the compressor?
Yes that's what happened to me
check that your compressor clutch is going on and off..... go from there
I have a question? We recently put a new battery in our 2004 Toyota Sienna and now there is a clicking noise coming from under the hood when we turn on the A/C. WHAT could THAT be?!
Hi, When I on heater, compressor also running. It is normal? Can you please help me with your correct answer.
What is the problem, when i recharge my ac the compressor get very hot when i start the ac system
Mine works, i just recharged it put in one 12oz can, it blows cold air now…might need another can, but clutch was coming on every 7-10 seconds, but it makes a ratteling noise?? Just had a new compressor like 6-7 years ago. I put in freon till the green pop up thing stayed ip when compressor was on…then i checked an it was blowing cool air, but the clips didnt turn color?? See how long it works i guess??
What does a compressor cost for that Toyota.
Only the back ac is working for me any ideas??
I need help the ac compressor in my 03 yukon engages and disengages and doesn't cool the car off and I have the manual climate controls
Was just wondering if the ac compressor can cause the car to sound like it doesn't want to start if it's going out and the clutch is making noise
@Nimble KIlla just drove my car to L.A. for the week and car died. It was a faulty battery and it fried my alternator. Changed both and car runs like normal. Still have the sound which I think is coming from the compressor but will look at it sometime this week.
@@mr.raiders70293 years later...what happened
Hi. I HAVE MUSTANG ECOBOOST 2017 american car. I am using it in dubai. I have AC problem. AC gets hoter as I drives. It cools better when i stop the car or release ACCELERATOR. I tool the car to many workshop and they still couldnt diagnose the problem. As I take the car to workshop it works perfectly. Sometimes they checked the pressure and said that the gas is more and released gas. The gas pressure increases and the compressor stops working. One of the technician told me that this could be problem with thermostat and they have to replace the thermostat which is a long procedure as they should dismantle the entire dash board. Some people say that the compressor might be bad and all. I am not able get a proper solution for the same. Could you please advise me what could be the problem?
Hey I have a Toyota 2008 Yaris
My compressor colds at idle
But when driving it get warm
I’ve changed the control valve and expansion valve.. still having the same problem. Help! Thanks.
My car a/c not working properly. And cooling fan working at high speed. If I pour some water on condenser start cooling. Car is Toyota Corolla 2013 model. Variable displacement compressor. Compressor takes delay for getting on even I switched on a/c. Please tell me the possible fault
Thanks

Thanks man my car has the same guage readings, glad this video is up. Time to get digging in the engine bay🙃
Hey my ac in my Honda blows cold on one side , I changed the blend door actuator , but it still does it . Any suggestions
Thank you! Question: would the compressor not be making noise if it was getting weak?
what if its making a noise?
Great information thanks alot same issue I'm having with my ac driving its cooling but not maximum and at idle I boil...
Is it true that a malfunctioning thermostat sensor or thermostat cooling engine effect compressor operation?
Mine will stay hot for about 8 to 10 mins, Only the fan will keep blowing despite driving around.
After 10 mins, it will start working normally. I can park, switch off my engine, and twill still work when I need it, but the whole thing repeats itself the next day...
What sound was the car making? Was it making a whining noise?
Probably lose belt is all
I have this Honda Brio amaze and air is not cooling during Idle, only when the car is running or giving it a rev. what do you think I should replace? both Compressor and condenser?,. thank you,.
If you were to replace this part, how much would you charge for installation? Just asking because I don’t want to get ripped off
1 million dollars but for u friend 2
Please make another video showing different how to read the the sight glass
suction line blowing out after two replacements. rubber hose with crimp on connectors.
Can I still drive the car with the bad Ac compressor
I have a 1994 Chevy pickup and behind the pulley on the compressor its showing some green bubbles. Will a leak repair stop it or do I need another compressor?
You would want to change the entire compressor vs repairing it (it's cheaper to buy a new one)
Thanks for that information
Can low Freon cause the compressor to not work also?
yes, if it is setup with a low pressure switch. would start by visually looking for leaks on the system (usually they will leak some oil as well which may have a green dye in it) then, using proper gauges to check the pressure and adding some charge if needed to get the pressure high enough to close the switch.
Checked the AC on my GF 2004 Toyota Corolla that was blowing hot air. The magnetic clutch doesn't engage / spin on the compressor. With the AC turned on the fan under the hood doesn't spin. Checked the AC relay by swapping it out with the horn relay, horn didn't work, AC relay was bad. I replaced the AC relay but it didn't fix the problem. The fan still doesn't spin and the magnetic clutch on the compressor doesn't engage / spin. Not sure what to do and can't really afford going to a mechanic (they quoted me $125 just for the diagnostic).
if the glove doesn't fit you must acquit
badass video thank you good sir
my exact problem thanks man hey what brands should i stay away from i need a new compressor and thinking of getting a piston upgraded from a rotor style on my 2006 mazda 3 2.3 l ????
my freons good -fans hi/lo good -clutch engages on comp etc -must be a weak compressor car is at 170 k so?
Great analogy about the AC compressor. Made it much easier to understand lol
What about loss of power when the ac is turned on !? Is that another symptom the compressor is bad?
Thank you great help
2013 Chrysler town and country 400,000 miles my car I never change compressor I drive in the highway is cold warm you can help me
