I own a 2001 Nissan Frontier and I just found your video. My ac stopped working a long time ago and 2 shops were convinced my compressor was bad. I didn't have the money so i drove without ac for over 3 years. Last weekend my buddy who owned a garage for yrs started playing with it and we realized the negative wire to the low pressure switch had a bad spot. We ran a line and it kicked right on. Added 1 can of freon and it's ice cold. However, it doesn't kick on and off it stays on. Thanks to you i know where to investigate.
Remove your ac relay. If it still stays on, you ac clutch maybe stuff into the compressor. Not surprised coz it’s been sitting for 3 yrs.
I hope you get it situated 👍🏽
I had the same issue, this video saved my 2009 civic ac. God bless you
I’m glad it helped 🙏
Every8th Gen Civic owner needs to see this video!
I'm mass sharing ;)
Thanks for finally solving this issue @Auto Purieu
Thank you for your support 🙏
Nice video, I fixed my AC problem based on your video. You are awesome! Thanks a lot.
Awesome . I’m glad to hear success story
Great video! I replaced my ac clutch, which was not an easy task because of the snap rings lol but my ac clutch was still spinning (engaged) this video was just perfect in explaining & is exactly what we subscriber's need lol thanks brother!
I appreciate your feedback brother 🙏 Godbless
@autopurlieu it worked! It was the relay fuse, thx alot!! Keep up the great vids
@@alcar45 that’s awesome 👍🏽
2014 Civic - exact same problem - thank you so much for helping me find the solution
I’m glad it solved your problem .
Thank you for your support 🙏
Bro lol, this burned up my old compressor, replaced entire system and then noticed the A/C stayed on because the evap kept freezing. Thanks for the video !
Ohh man . I’m sorry to hear that. Sometimes you’ll notice an ice build up on the low side lines of the system.
Man, I bets that’s a nightmare
How do you prevent it from building up? What was the solution?
@woodchristopher93 his answer wouldn't help you because theirs afew different situations that can cause the evaporator to freeze over from a clogged condensor, to a dirty cabin filter, low freon, etc...
Same I'm having the same issue, it gets completely frozen but my fans stay on all the time
Having the same issue with my Accord, gonna try this out
Thanks for the vid. Don't assume we know stuff like what you are looking at under the hood. I have no idea how you know the AC compressor clutch is engaged.
I just had the same problem, but thankfully mine was a cheaper fix, for me it was simply the relay needed to be replaced
Hi. I also have AC always on. Additionally the two radiator fans are always On too. Even when I just turn on the ignition the 2 fans start to spin. Did you have the same problem with fans in this video?
1) I tested all the relays. They are good. Ac clutch is good too. No OBD faults.
2) When I unplug Ac relay (as you do), Ac stops working but both fans are spinning. Fans only turn off when I unplug the Fans relay.
I checked the connector of one of the fans, and there is ground even when car is off.
3) When I unplug the Ac connector then everything turn off (Ac and both fans).
Thanks in advance
Have you figured out this issue? I have the same except when I unplug the HVAC controls my fans and compressor stay on.
@@Roootrocker228 It was indeed the control panel. Everything works now
Thank you so much for your video my car is doi g the same exact thing now i can check my car out on Saturday
Good luck my friend. Let me know how it goes
Changed my whole AC system. Finally visiting the service center tomorrow. Hoping to get this fixed in my Hyndai Creta-
Also if you can suggest how to stop the air flow on windscreen in default mode ? It fogs my windscreen and i have to use vipers all the time. Seems some air leak !
Love from India
Hi, is your air flow on windshield on default mode on activate when you just starts the car? What car year and model ? Also are you be able to change the setting or stuff in windshield mode all the time ?
I am confused on why it would stay on if the ecm is the one that usually provides ground to a/c compressor. Wouldnt it still cycle on and off? Great video and you saved me a head scratcher.
It just sends a signal to turn on or off, the relay is responsible for activating , relay has a mechanism that allows it to turn on and off, if the mechanism inside the relay fails it will not matter what the ecm wants.
Awesome video. My problem is different tho. My previous AC compressor burnt up because the AC clutch stayed on all the time (when the switch was on and would turn off when AC was off). Figured since it has never been replaced, it finally gave out. So I replaced it with a new AC compressor. For a year it worked perfect and then the same situation started happening. Never fixed the issue again since the AC still works. Yesterday night, finally decided to work on it. Took the AC clutch apart and cleaned it up with sand paper. Cleaned all the sand that was in there. After putting it back together. It worked perfectly but then the AC clutch engage when it had too and then got stuck on again. When I turn the knob for the AC inside the car off, the AC clutch turns off. So after watching this video. I'm assuming is the AC relay that is probably bad and gives it power constantly when I turn the switch on. So I gotta swap it and try it out too. Is summer and I don't want it to burn up on me again.
Or could just be the switch as well that is giving constant power to the relay.
Yah just check one area at the time to figure out which one actually give constant power . It’s sucks that happen to you
@@autopurlieu Thank you!
@@autopurlieu So I tried switching the relay just now like the 2 that you switched. Turned it off and on and works the same. Hit the turn off AC button inside the car and works the same. AC clutch turns off when is suppose to with the switches but when is on, keeps on running unless I turn it Off the system then it stops. So another faulty AC compressor, I presume? Switches function properly, switched relays and they work perfectly, cleaned the cluth and sanded it down, no shortage on wiring. The only thing left is the actual compressor then. Unless I replaced the AC clutch coil but then is gonna be more work and money if that doesn't work and the entire compressor is gonna have to be swapped.
@@TheDeathsentence123 try this out

What causes ac compressor not cycling
I got 2013 honda civic lx, and noticed that pipe is freezing up much and after 12mins drive im losing my AC, no cooling. I checked Ac clutch and relay found out that AC clutch not stopping even the climate control is turn off. Im sure that i am having same problem with this. Hopefully there is no more issue after fixing my climate control as i am having frozen pipe often. Thanks for the video anyway.
Did that fix it?
Wow thank you man I’m having the same issues with my 07 Honda si
I hope it fix your problem, keep me update
I'm having the same promblem ac clutch disengages after like 15 promblems tested the relay and compressor and there all good and have power ..
@Thatzlyght lmk if u fixed it
@@kegandelmar8489 I think your situation is different . Check my other video . Might be related to your situation
ruclips.net/video/MjMa-faktVw/видео.html
@@autopurlieu I have a si it shouldn't matter huh?
I think you just helped me diagnose my BMW! On my car only the front vents will open but not the bottom or the defroster and my AC turns on and off at times or sometimes no power
What year model bmw?
Scanner can probably pinpoint somewhere on ac problem you’re having
It’s a 2012 bmw 535i , I scanned it and this is what shows…. Integrated automatic heating / air conditioning system ІНКА.
So I noticed yesterday when I was moving the AC controls around it would turn off like the whole control unit would turn off unless I placed it in a certain way everything would turn back on, so I’m thinking it’s the AC control module that’s not working , And that scan also tells me which vent flaps are not opening, and I’m thinking it’s because of the AC control module possibly not working.
@@joerod7176 yah sounds like you find your culprit. Good job man . I would think to start from there
Thank you , I appreciate you responding to my comments
@@joerod7176 no problem. Thank you for your support 🙏
I just had all my freon escape from the relief valve from the compressor staying on consistently.
Turned out to be the relay was stuck on, which also caused my battery to drain everyday and need a boost. New relay and i added freon that was lost and its kicking on and off with ice cold air 🥶 also the battery drain is also gone
Is that a pre fabricated building?
Watching from France...Same problem with my Honda jazz 2005..Radio function but no heater .I changed the module,but the problen still existe..I am going to change the resistor of the blower to see..Can you help me Sir and waiting for your answer..Merci and Thanks a lot..
If no heater, check your coolant. Maybe not bleed properly and heater core might be culprit too
Hello, I have the same problem but I wanted to ask you if the two fans, the one for the air conditioning and the radiator, turned on because that is what happens to you that the two fans keep on. Thank you
I’m sorry, I don’t get what you mean “my two fan is on “
I’m not focusing on the fan.
I’m focusing on my ac compressor was kept on
That was awesome thank you for sharing it
Thank you for your support 🙏
Can you show us what you would have done if that didn't fix it?
I'm having a similar problem with mine. I've gone through all the same steps you have and my clutch stays engaged. I've even gone as far as to unplug the evaporator temperature sensor and it stays engaged.
Not really sure where to proceed from here.
Have you checked your relay? Maybe it’s stuck closed
Have you found the problem? I’m in the same boat with my civic si!
Good video, Best
Thanks 🙏
Same thing happened to my civic. Same solution.
My 2012 Volvo s60 my a/c is constant on it’s not shutting off even when my car is off what is it ?
You should try and diagnose it
Hi , I have a 2007 crv, I have the same issue, but when I unplug the AC control module inside the car,the fans still stay on. I pulled the relay for the compressor also and it’s still on.
You might have 2 fans. 1 for radiator and 1 for the condenser. Are you sure you unplug the right one ?
Sorry, I removed the relay for the compressor and the fans are still running. I also unplugged the control unit from in side the car like you did and it still runs both fans.
@@stevefrancis7322 your might be short ground somewhere .
I believe I have another video that shows how to check each component but it’s an accord. Should be the same components . Just look it up
Good video!
Thank you
Does the A/C fan stay on continuously when the A/C is on or should it cycle on and off every ~1 minute?
It should cycle only when it’s on
@@autopurlieu mine is staying on continuously, I’ll have to figure out why it’s not cycling
Thanks
@@martymckay297 Did you find out what the problem was? Wife's Jazz/Fit clutch is always on if A/C is pressed on (no cycling). Also one of the two fans is always on at the same time, the other is never. If A/C is pressed off, neither of the fans are on.
@@pallikorva11did you find the issue? I’m having the same problem! 😒
My compressor just says running but can turn off on the switch?
Check the switch if sending signal. Or maybe even relay is stuck on
When my car is stop the ac works perfectly but when I move the car the clutch gets off and also the cold air. Any suggestions for me
When you said “car is stop “ means in idle ?
@@autopurlieu I mean when I turn on the car until I don’t move it the ac, cold air, and compressor clutch works but when I push the gas and move the car cold air gets off, compressor clutch also doesn’t move. Only air blows no cold air
@@whatwhat3437 I would start with basic. Looks like you have power . Just check the ac pressure line if it’s in good and proper pressure . Maybe you are low on freon
Hello! I have a problem!!! I filled my 2008 honda civic ex with freon. Now the ac fan won't shu off it stays on all the time
Check with the basics to diagnose each components. I have more video that relates to AC.
ruclips.net/video/KJ2fFCpyW20/видео.html
Best of luck brother
Are both fans supposed to stay on when A/C is on??
What’s going on with that Z3Coupe ???
That’s my baby 😂
Are there some newer cars where there is always a little something blowing out?
What do you mean of that?
@@autopurlieu like you turn off the ac or heat but it seems like a small amount of air still comes out
@@SonicBoomC98 is your blower motor is off? Maybe your recirculating vent isn’t on
very helpful video
I’m glad it did 🙏
@@autopurlieu my car has same problem i fixed new switch
Hi. Ok my ac compressor stays on but i get warm air when stoped but driving i get semi cold air but when i go all the way to hot then back to cold it gets way colder. Fuses an relays must b good if it workin just compresser doesnt kick off an on. Now it is a 14 yr old one an i also removed the shime for the face plate to move n closer. Both fans work. I did put a used climate control switch with all the buttons about 1 month ago it worked perfect for the first 2 days either stopped are driving but then started doin the same thing then noticed compresser wasnt kickin off an on? Any thoughts would help alot thanks
I would start replacing with a relay first. Relay is relative cheap. Then it keeps doing it, make sure you have proper pressure inside the system. Always start with simple diagnostic before going further
I did earlier and still doesnt kick off an on. Ill get somebody soon to put guages on it and maybe change the high pressure switch.
@@codybenoit394 did you check if you’re getting power ? Start with electrical, it’s easy to figure that out. . Is compressor getting power ? Then do elimination process going back to the fuse.
Yeah ac runs fans work. It just gets warm when i stop but driving sometimes it doesnt get all the way cold. So when i move the hot and cold knob back and fourth it gets way colder.
@@codybenoit394 yah, get a small gauge. Pressure in the system change depends on the outside temperate . Might be overcharged or not enough pressure.
Good luck brother .
I have a 2009 Acura TSX doing the same thing. The compressor just won’t kick off. It starts as soon as I start the car
Start with basic
ruclips.net/video/KJ2fFCpyW20/видео.htmlsi=0IlAI7FPtfLNZXJH
@@autopurlieu mine starts. Just won’t shut off. Constantly blowing cold air. Clutch never stops spinning. Removed relays and it still keeps going.
@@kentman0767 sorry, misunderstood your wording. I’ve never heard saying ac compressor “starts” .
Check your ac clutch compressor , it might be locked up.
When the car is off, sound the outside part of your ac compressor, it should spin with your hand. If it can’t, it’s locked up
@@autopurlieu it’s ok. Sorry as well. The compressor clutch spins constantly. It does not cycle.
@@kentman0767 that’s why check your compressor clutch .
If it’s locked up.
Sounds like the starter is bad, at least one of the brushes is burned out.
Starter related to ac ?
@@autopurlieu No, just an observation. Slow cranking like that one has is symptom of the starter having 1 or 2 burned out motor brushes. Common issue.
@@superjesus4307 if it ain’t broke, don’t fix it 😆
@@autopurlieu It is broke though lol
@@superjesus4307 ac was broke not the starter
Anyare
Bad climate control module. Nood ka kc lol
@@autopurlieu nasa labas ako haha napanood ko na pre buti may spare ka ng control module
@@fernanfeminliu always have a parts car hehee
If the climate control worked what else would power the AC?
There’s plenty of variable for that. Fuse, relay, high pressure switch, etc etc
I have an 06 m45 Infiniti. I walked out the gas station and turned my car on to find my nav screen won’t turn on and ac control module button don’t work at all. First time and random. I don’t know where to start. All of the fuses I checked works.
Dream of Hindutva is not fulfilled,they will do such dramas
Ok so mine keeps cycling the fans and compressor every 3 seconds with heat on in the morning. It's so annoying! I do not sure the AC at all I just want heat. I'll have to watch this full video tonight see if it helps.
Check the ac relay or the ac compressor clutch
