Because being a mechanic isn't challenging enough, you actually hold a camera whilst actively troubleshooting and then speak your thoughts out loud and troubleshoot in a methodical, logical manner for the benefit of all to witness. Superb work!
And to top it off, sounds like he's got some allergies or something going on
@@barbarakdoty6843hahahaha fr tho😭
Head cam
Mr I was having the same problem ,did everything Luke you mentioned on video and it works,I have a OBS truck that ac will work and sometimes didn't work ,well the clutch will stop engaging so I took it to a ac mechanic and he was nice to me that he fix the problem in front of me,he took out the bolt out of clutch and pulled out little whaser and put back bolt and clutch kick in ,I until this day haven't had any problems with ac.i really appreciate you taking your time and showing your knowledge may God bless you always. 👍
I cannot thank you enough for this AMAZING troubleshoot video. My 2013 ended up having the exact same issue.
I wish I had more hands, I'd give this video 4 thumbs up. As soon as I saw that charred connector on yours I went straight to mine and found the same charred ground pin. Flawless troubleshooting on this video!
I really enjoyed this video. This test had me to conclude that it was my wife's HVAC control that was going bad. After listening to the clutch engage five times and then getting a positive 6 volt signal from from the high low switch .We found out that the command signal from the HVAC climate control wasn't coming on. Very informative video thank you again.
How did you fix that?
I have been scouring the internet for JUST THIS video! Thank you so much!
Hope your cold got better 😂
Two years ago when I first watched your video I followed the instructions as you stated. Unfortunately, the original AC compressor on my Nissan was no longer good. I also did a test where I moved the entire clutch, but was unable to since it was seized. This new clutch I had lasted about two years or so, and went out again again I did the exact same thing, followed your steps and it turned out. I have the same issue with the connectors. I don’t have a replacement connector nor those that you used in the video, but I just cleaned them off and using a pic. I clamped down the connector on the female side and reconnected the cables and the clutch engaged again temporally using that for now until I go to the dealership. By the way, I just wanted to thank you for making this video very informative and helpful.👍😎
By the way 2015 Nissan Sentra SV.
Ill be checking all these things first time tomorrow morning. I didn't know how the door test worked. I checked on my fuses, nothing blown. Replaced one with a partial connection. Still no clutch engagement.
I want to thank you so much your video helped me fix my ac after I had already taken it to a shop to look ND fix it and they couldn't make it work. You were a blessing thanks again.
Thank you for the kind words.
I just wanted to take the time out of my day to say thank you. This exact problem has happened to me just yesterday. I did the test like you did turns out that same connector was the issue. Thank you!
I have been having the same issue on my fiancés 2015 Altima. Same exact symptoms and this helped out tremendously. Definitely buying a test light tomorrow and checking pins on the IPDM and on the a/c compressor. Such a great detailed video and very helpful
Did it work?
Your a life saver man great job im fixing my a/c tomorrow. Thank you 👍
Big Thanks for putting this info out. Saved me a lot of hassle.
Thank you very much for this video. I knew mine was in the wiring but you helped me pin point the problem. Excellent video!!!
2013 Nissan Altima 2.5 SL (3-9-24)
Same exact issue
You hit the nail on the head with this one sir , saved me time and money.
Simple process of elimination, 🐀mechanic straight up lied to me said i had a compromised system and was going to need new compressor , dryer , & condenser.
My ipdm was sending power clutch was not engaging sure enough discovered that burnt out connection.
Brother, I am just like you, my mechanic He also told me that the air conditioner compressor was broken and needed to be replaced, but he didn't check the connector at all.
Seems like a common Nissan problem.
I’m having this issue now but I’m sure this video will help.
Thank you!!
I just wanted to thank you very much very professional skills and educational crystal clear pinpoint
that's exactly the test im trying to do on a 2013 maxima, just come home to print diagrams and in mid time i found you video.
Did the test work on the maxima?
Thanks for that detailed diag. Now I’m going to apply that same technique to my 2015 Altima 2.5l with the same concern.
Great video ! That IPDM test is a great tip.
very good. thank you very much brother. I would like to know if for the Altima 2018 it is the same procedure?
Thank you so much for putting this video together! I have a 2014 Altima that had the same exact problem and this fixed it!
So u just changed the connector? My ac went out today on my 14 altima
Amazing how you broke it down and described it. Having the exact same issue
Thanks for this. I had the same exact problem. Working great now.
Did you also solder them directly in the the pigtail like the video?
Thanks man, can confirm this is common and was the fix I needed! #2023
Firestone told me I had a bad ac compressor so I replaced it myself, I have a Sentra with the 2.5 so it sucked! After vacuuming the system I started Adding freeon and the clutch still didn’t engage. So I’m right back to square 1.
Thanks for your video I was able to run the diagnostic and the clutch & fans do engage. I’ll keep doing research until I find the problem 🙄
Did u ever find it?
Thank you so much for your help I’ll check mine tomorrow
great job on the information that i've nev
er thought of or heard. i really appreciate the attention to detail.
Thanks buddy.
Thank you so much for making this video, really helped me out
Thank You!!!!! Amazing video, saved me a ton of money! Keep ‘em coming!!!
awesome video. why of why didn't I view this prior to swapping the compressor, condenser, and expansion valve! btw 737 mech nice, retired 737 pilot here
Im confused about which pig tail to take off. It wasn't clear in your video. Everything else is so helpful and thank you very much
So there is a plug that is directly plugged on the clutch and then there is a plug about 3 or 4 inches from that one. The one 3 or 4 inches is the one you cut out and splice, basically getting rid of that smaller plug.
All cars may not have the plug at the clutch some have the wires directly connected .
737mechanic that's what I have and it's difficult to reach. I did unplug the pigtail, and it looked fine, not burnt from arcing. However I couldn't reattach the plug to the other plug, will try again. May our Lord Jesus ,bless you and keep you.
This is very helpful but if the AC clutch was bad you would still not hear it and might think the wiring was bad. I had a bad clutch and there are videos on how to replace instead of the whole compressor.
Great video! So what caused the connector to arc?
Once again great video thank u for your knowledge
Awesome, video brother. Thank you . This video helped out a lot.
GREAT VIDEO, THANKS FOR ALL THE INFO.
YOU DID YOU JOB LIKE A PRO. YOU HAVE MY LIKE WITH LOVE...
thanks for the video! very informative and helpful!
I was wondering why the connector would be bad if it was getting power. Than I realized you were testing the blue wire in the back of the connector and not the front metal contact. Having ac issue on 2014 pathfinder. Isolated it to the connector or compressor .
thank you for teaching sir 🙏
Thank you for the info same symptoms and this fix it thumbs up 👍
Great info! Great narration!
Awesome diagnosis ty sir. Ill do this rn.
Hi were you get the connector from the red and black wire ?
very informative video. thanks
looking all of your video, it might be a common problem on these nissans
Great tutorial! Thank you!
thanks brother, very usefull especialy the trick of computer my nisan is 2007❤❤😊
Thanks for the video. After watching i was able to figure out the clutch wasn't engaging on my 2016 Altima. I picked up a light tester at AZ for $8 and tested the power/ground wires at the clip going to the clutch and both seemed good. When I plugged the clip back into the harness the clutch started engaging again and the ac came on. 🤷♂️ I suspect the clutch is going out or the connector clip is.
Probably bad connection.
@@737mechanic Ended up replacing the connection today. The clutch was working intermittently but seemed to fix whenever i unplugged and reconnected the connectors. After closer examination, the terminals looked burnt very similarly to yours. Replaced it with a $5 Dorman connector and so far no issues. I'll just have to wire the new connector to any new clutch/compressor i install in the future but no big deal. I will note that the black/red wire harness connected to the clutch did not have a clip to remove it from my compressor so it was alot a leaning over and difficult reaching to get it wired together but it was doable. 👍
I'm having same issues on my Nissan 2016! What's your recommendation bro
Great Video! Solved my issue!
That was awesome. Just one question, I was hoping you would have done the ground and power test again with the test light with the adapter plugged in before you cut it. But otherwise that was amazing.
Good job sir thanks
This was a great video
Thanks for the info
Thank you so much my friend
Great video!! Saved my day..
hey I did my test on the IPDM and it works properly.. but it will not command it by pressing the AC inside. it does show that it's commanding the ac on via data on the scanner, but it shows off on BCM... a/c control box? it does have automatic a/c, is a SV model...thanks...
Does the 2012 altima do this ? My a c is doing the same thing. Sometimes it works great. Sometimes it doesn’t come on at all
Is this procedure the same for a 2004 Nissan Maxima?
Thank you very much for your video. Super nice,here's my question, after run the IPDM test, clutch engaged,but dosen't work when turn the ac on, what could be the issue ? Thanks again.
Could be low refrigerant, bad inside or outside temp sensor, low pressure switch.
thanks. raychem brand splices are awesome but expensive at 1$ per splice in 50 splice packs. without the heat gun reflector kit, you do better with a BIC 1000 but use the blue part of the flame or it will char.
Shudddd uppppppp! Stop 🛑 coming on another man's page, and telling him how to fix something he didn't ask for! It's a faux pas to do that on UA-cam. Wanna be like this man, and give advise on UA-cam LIKE HE DOES? MALE YOUR OWN UA-cam PAGE AND POST UNSOLICITED ADVISE ALLLLL DAYYYY LONGGGGG! And when a person comes along, that may or may not benefit from your video, they can take your unsolicited advise. But it is ethically RUDE, to get on ANOTHER MANS UA-cam CHANNEL, And let him know that the advise he gave war incorrect, or not valuable bc it's more expensive than you'd like. And even though you could mention this in YOUR video, it is EXCEPTIONALLY RUDE AS FK TOO DO WHAT YOU, just did. If you don't understand online adequacy, then take a class, watch a video, or just simply mind your own Godd dam business brother. With all that said, I hope you have learned something today about online behavior, and please understand, that anything I said or way I said it, was not meant to be mean, or make you feel bad about yourself, but to show you how stupid you sound and look doing it. Have a great day, and you can reply to this message if you are interested in joining a online class, taught by me, "How To", Go Fook Yourself, properly and effectively. Thanks and best wishes to you and your idiocy.
Where do you find the diagram ipdm fuse box?? Nice video
Great video. My ac clutch clicks with the ipdm test. Should my ac kick on even without pressure? Just bought the vehicle and there’s little/no pressure in the system. Thx
No, if there is not enough pressure the pressure switch will prevent the compressor clutch from engaging to protect the compressor.
@@737mechanic Thank you charging now
My car is a 2013 Nissan Altima and has the same condition as yours the clutch in the compressor is not engaging... hope this information helps me save some money.. cause I have been told my compressor is not good any more..thanks 😊
You might want to see if this video helps also.
ua-cam.com/video/SA_IE7WivHU/v-deo.html
Great video, I followed every step and the clutch is engaging but the ac qont turn on, anything else? The light just keeps flashing when I turn on ac. There's power all the way to the compressor and I visually verified that the clutch is engaging.
First, make sure the system is charged, and if it is and you have a compressor with a compressor control valve that is most likely your problem. They are a high failure item but are cheap and easy to replace. Make sure you discharge the system first before removing it. ua-cam.com/video/q6TOfsDUL3o/v-deo.html
Hey so I ran the exact tests you did and my ac is blowing hot, Clucht isn’t engaging and blowing burning smell. Im woundering if I do this will the clutch start engaging and will that fix my ac issue?
It will fix the problem if this ends up being your problem.
VERY NICE AMIGO THANKS FOR SHARING
My ac isn’t blowing hard but my blower motor and fan seem fine I bought a ac blower motor resister replacement could that be the problem? It’s cold ac but not blowing hard anymore even on full blast circulate mode
If your blower motor seems fine and goes from low to high but you don't have much blowing from the vents it may be a mode door not moving from one position to another.
Thank you!
Do you have a link for the control valve connector? I can’t seem to find one for my 2013 Nissan Altima SV
Hows it bad you had power to it
Will this work for a Nissan maxima
Im not sure but it would be worth a try.
Thanks for the video! I performed the test and the clutch is not operating. I bought a new relay from Autozone but am having trouble locating where to replace it. Can you post the website where you got the relay schematic for this car? Is the MG clutch relay built into the IDPM? Or is it a changeable relay? Such as, one piece? Thanks.
Did you check the compressor connector and see if you had 12 volts while doing the test?
When you do the 10 door press test.....if there is no freon will the test still click the ac clutch 5 times?
On my 2012 Altima, the AC was working great then for no reason, stopped blowing cold air, and the clutch does not engage when the car is running now.
When I do the test I can hear the relay clicking by the power distribution box, but the ac magnetic clutch does not click.
Thanks!!
I'm 100% sure the system is charged. It always blew cold air, right up to one random day. Fuse tests good.
The clutch should engage even if there was no freon. If you hear the relay clicking but the clutch is not engaging then you either have a bad connection from the IPDM to the clutch or you have a bad clutch.
@@737mechanic thank you so much for the reply! I will use my test lamp later today to see if 12V is making it to the clutch connector.
So when I do test clutch does engage 5 times and with engine off I can freely spin clutch so that means clutch is good right ? I put the can with gage it is in the green shows charged however blows hot air
The clutch should be good if it engages 5 times during the test. If yours has a compressor control valve the valve could be bad, or it could be the pressure switch.
If the compressor engages with the car running but it is not cold replace the control valve. If the compressor does not engage with the car running and it is fully charged with refrigerant check the pressure switch.
Here is a video on replacing the control valve.
ua-cam.com/video/q6TOfsDUL3o/v-deo.html
And here is a video on replacing the drier which has the pressure switch on the top of it.
ua-cam.com/video/zeZaXBm351E/v-deo.html
Hey what could be my problem I have a 2016 maxima V6 I ran the test and the clutch engages five times but when charging the system the clutch does not come on is it that I PDM or pressure sensor what could it be
Its not the ipdm if it cycled 5 times, that tells you the ipdm is capable of turning the compressor on if it needs to. I would suspect the pressure switch.
Great video
How do you test the control valve?
I replaced the CV and when diagnosed it send a signal to the AC compressor but the clutch does not engage idk if I'm pressure locked out or a bad control valve...I really appreciate this video a great job 10/10
The CV will not inhibit the clutch from engaging so if the clutch is not engaging you need to figure out if you have power at the compressor connector. If you do but the clutch is not engaging, then you have a bad clutch or possible bad ground.
0:20 how did you check the refrigerant? My IDM seems fine... the clutch that you describe at 2:45 seems to be engaging in my car during the test but it doesn't seem to engage when the engine is on to circulate freon in the system to get the cold air to blow. I'm not sure what is wrong with my car.
I didn't have to check the refrigerant, when I did the IPDM test and seen the clutch would not engage I went after that problem first. Once i repaired the bad wiring to get the clutch to work it cooled fine.
I did but test and my clutch on the compressor did click 5 times
What does that mean for me???
And the relay clicked 5 times as well
Should I change the relay just to see or what should I do
The relay is good if the clutch engaged. I would check the refrigerant level, the pressure switch and the temp sensor.
I tried to use a inexpensive voltmeter to check the relay and the plug that comes from the compressor. Couldn't get a contact with wire in relay box or compressor plug with the meter probe. Could I jab a peice of electrical wire into the relay wire and plug wire to determine if I have power to both, using my voltmeter? Thank you again and may God bless you abundantly.
Yes, you can use a piece of wire if needed.
737mechanic I'm getting power to my compressor, a technician at Autozone told me that your clutch won't engage if the pressure on either on the high or low side isn't within specification. Is that correct?
@@robertmccann380 that is correct.
Hey bud great information but im a bit on the dim side lol. my altima, the compressor clutch engages 5 times during the self test but when running normally it dont work. Can you give me a hint lol. id guess the comp control valve, expansion valve or the high and low pressure sensor. The self test passed all tests as far as i know, so it wouldnt be the ipdm or the plug you fixed on yours. im not the best with a multimeter, i guess its time i get better. you do great work and a great service!
The first step is to make sure it is full of refrigerant, The control valve and expansion valve will NOT prevent the compressor from coming on so those are not your problem. The pressure sensors will prevent it from coming on. I believe the ambient air temp sensor will also prevent it from coming on. You need to hook a scan tool up so you can see if there are any codes and look at the live data to see what the pressure sensors and temp sensor is reading.
Mine passed the test as for the clutch engaged 5 times . So should I replace the pigtail or check other things. When I did the idm test I didn't unplug anything and lights ,wipers fans ac clutch engaged 5 times. But no air and clutch doesn't engage when I turn it on in the car . Ac compressor fuse is good
thank you
Thanks for the video! Just what I needed to troubleshoot our niece's Nissan 👍
so what happens if my clutch engages and still i don’t have cold AC what else could be the problem
It can be the compressor control valve or expansion valve.
Can I do the is with 2018 Nissan Altima?
It won't hurt anything to try it. I would think you can.
Hi brother I did the testings and all seems to be going well the clutch kicks in in the test..so does the fan also start..but..when I start the car neither one of them are coming on/ fan nor clutch... could it be the compressor control valve..? Thanks for your help.. God bless you
No because the compressor will be running even if the compressor control valve was bad. I would make sure it is charged up enough and I would suspect the pressure switch.
@@737mechanic thanks 👍😊
Ac was blowing strong cold air, then cool now warm. Had it checked again w new compressor/condenser replaced 2021, 22' another compressor almost a yr ago. Changed cabin filter helped but now this again. I feel they missed something or didn't chk everything or like u did. Help😢
Does a/c clutch go on and off when the a/c is on and the car is working on idle in park gear on 2010 nissan altima?
Depends if it has a compressor control valve.
@@737mechanic It has one pressure switch next to the radiator
What if I don't hear any clicking sound from the ac relay
Where did you get wiring diagram?
Pro Demand
Thank you for the video. I did the test and my clutch for the compressor turns on but it’s still won’t blow cold air. I put freon on my car and still no cold air
Does it come on when the car is running? If not it could be low or out of refrigerant. If it does it could be the control valve. Feel the low-pressure line and see if it is getting cold.
ua-cam.com/video/idWedXJENKo/v-deo.html
@@737mechanic if it is still hot is it my control valve
Does that test work on a 2011 maxima?
Yes
Does this work the same for a 2008 Altima?
I am not sure. The diagram is similar so it might be the same.
What if the compressor do engages while doin the test ?? Is it the compressor itself needs to be replaced??
If the compressor engages during the test, check your refrigerant level and if it is good then replace the compressor control valve.
That’s the best question that has been asked in this thread
What is that actual double connector called? I'm looking to order a replacement.
They are weather pack connectors. Here are a couple links to some kits that might be as cheap as ordering just one.
amzn.to/3z5Ty2s
amzn.to/3AOjfWn
Can I try the same test ( with 10 times click on door ) with my Nissan maxima 2014.
I tried buy not working ...any solution
It may not work on all Nissan's but here is a video that might sow more detial. ua-cam.com/video/SA_IE7WivHU/v-deo.html
What happens if the compressor clicks 5 times in the test but the ac still don’t work with Freon in it?
It means the compressor is probably fine and the problem is something else. It could be the ambient temp sensor, evap sensor, pressure switch or something else.
If everything came on but still blowing hot what could it be ?
If the compressor is running, feel the low side line under the hood and see if it is cold. If it is but the inside only blows warm then the blend door is not working right.
DOES A 2019 IMPALA WORK THE SAME ?
The Gm vehicles have different wiring but the basics are the same. You still need to check and see if you have power and ground at the compressor.
So if we can hear the clutch engaging with the test, but turning the A/C on in the car itself doesn’t work, what would you suggest?
1st check the refrigerant level, 2nd check the pressure switch, and 3rd check the ambient temp sensor.
@@737mechanic gotcha, refrigerant is good. The rest I’ll have to dig into.
@@Dorizonohi, just wondering what you found? I replaced the AC control valve but the compressor is still not kicking on while running although the test worked.
