I have a 2014 altima that the ac was not working correctly. I saw this video so I ordered a control valve. Got under the car and found out my car doesn't have one of those valves. Darn. I say look before you leap
You can clean the valve in gas and spray air, and replace the seals. That’s all what’s needed. If you have issues with rear ac leaking but rear block off kit from street rod guys in USA 90$ perfe t fix and your ac will freeze again and only fill half the Freon. Nissan purposely designed the pathfinder set ac rear lines to pit and leak thousands of dollars in parts and costs! lol
Uggh I installed one of these in my 2015 Altima. Turns out this is only sl sv models. The base and s models don't have this part or compressor
If the A/C is automatic it will have an CCV. If it is manual A/C it will not. SV and SL come standard with automatic A/C.
@@737mechanic yea my model was supposed to have mechanical vs electrical component.
I have a 2014 Altima. I cannot thank you enough for this video. They were trying to have me replace the compressor and this video saved me over 1K. I paid $25 on Amazon for the part and $200 to get it installed and now it throws ice cubes. Thank you so much!!
Damn near penguins riding in the backseat??
Same problem & same fix here.. now it throws penguins out the vents!! ❄️🐧
That's crazy because they keep trying to get me to replace the compressor
In Texas and can't seem to get anybody to replace my ac compressor control valve
@32HUNNYB32 did you got it
Thank you very much for your video...just made this repair today on my son’s 2013 Altima SV and it was only blowing out warm/hot air for a long time and as of today it now blows out freezing cold air!!!!! Thanks again!
Thank you for this video!! It was so easy! I helped my friend and saved her $500+ bc every shop would only change the whole compressor. Worked like a charge with this and a new charge!
I have a 2014 Nissan Sentra and this was the exact fix! Only different is the valve is facing the radiator so getting to the snap ring is a PITA as opposed to this view, but still the fix! Dealer wanted an astronimical amount for swapping the compressor, thankfully it was this easy!
ohhh Maybe this is my issue. I'm over here like I don't have a control solenoid valve 🤣 . Let me go look facing the radiator.
Can the control valve swap be done on a 2017 Nissan Altima? I don’t see my compressor having a control valve. 2017 Altima SR.
If your AC is manual you do not have the valve, only automatic AC systems have it.
@@737mechanichow to know if my ac manual or automatic! Thank you
@@SuperArmintiesto Look at the control panel and see if it has a button that says AUTO and if it has dual climate. If so it is auto if not it is manual.
This worked for my 2013 nissan altima
Men thank u u just saved me almost 1200 that I was told I bought mine for $21?and my ac works fine
I can definitely say this helps!! I got mine replaced and now i’m getting freezing air!
Things I do want to share. Mechanics will try to say it’s the compressor but it’s not, most shops will not allow to replace the single part which is frustrating because of “liability”
Research and find different mechanic shops to get your system evacuated, installed and recharged.
Luckily my local Kwik car and Lube charged me $200 for installation, evacuation and recharge with no questions asked.
All my respect to you!!!! Thank you for sharing your knowledge, you just saved me 1500 dollars my mechanic. I going back and showing him this video!!!
My altima 2013 ac is cooling at night time but not at day time. Day time only when car is moving its cold
Check the cooling fan and make sure it is running full speed.
@@737mechanic yes, it is working fine
@@ahmadxatti Make sure it is properly charged.
@@737mechanic should i replace compressor control valve?
@@ahmadxatti You need to hook gauges up and see what the pressures are.
I just had this repair done on my 2014 Altima. Now I have cold AC again. My AC would take a long time to start cooling. Now it cools immediately.
Man I watched this video months ago and took the advice and went and bought the part. I went to 4 different places to get them to replace and they all said they never done or heard it before and suggested a new compressor. Cost as high as $1200. I laughed in all their faces. TODAY I found an Asian family shop and showed him this video and he said 'Done'! this too was his 1st attempt so 4 hrs later my ac is blowing again. $200 charge vs $1200 😅
I really appreciate you making this video...
Thank you Sir! Two different shops told me my compressor was wrecked. $1300 to replace. I watched your video about five times. A neighborhood shop pulled the refrigerant out. I took the Altima home and followed your instructions replacing the pressure valve. Interesting, there was a pressure release (whoosh) when I pulled the valve out. Put the new one in, secured it. Then took the Altima back to the shop who evacuated and recharged the system. It took a moment for the compressor to respond, but respond it did. AC is nice and cold. (By the way, I replaced the expansion valve while the refrigerant was out) Thanks. ($42 pressure control valve wins over a $1300 compressor. Expansion valve was $19 at OReillys)
@737mechanic a shop told me my compressor was wrecked so I replaced it last year for a lot of money of course. Recently, it went in & out and now it only blows hot air. I checked the freon levels and they seem fine no leaks. I think I’m going to try switching mine out but I have a 3.5 so I have to figure out where the parts are.
I have a 2013 Altima s. It Doesn't have a pressure control valve on the compressor. Some do but some models don't have one
Informative, but would have been nice to see the result if it really did fix the problem. Thanks so much
I thought about showing that but I figured everyone knows what a cold A/C does.
@@charlesthomas2152 The air? You pull a vaccum using a vacuum pump. Then you put in the amount required as displayed on the label under the hood.
I'm looking forward to going after this. Thank you. This is one really great thing about you tube.
It worked on my 2016! Thank you !
Was it the base model or an SV/SL model?
Thank you, worked 100%. This is perfect, thanks for uploading this content!
Thank you so much for this detailed video! Super helpful!
would this fix apply if the mechanic says the compressor doesnt switch on?
NO, the control valve has nothing to do with the compressor coming on or not.
Do you know if this goes for the Base and S models as well? Or just SV and SL?
I heard that the base and S models do not have the compressor control valve, only a compressor without one.
Thoughts?
The SV and SL are the only ones that should have it. I think if you have auto climate control you will have it and if you have manual climate control only you will not have it.
@@737mechanic Right on. That's what I was thinking. I have the S model, and I'm going to look into it
@@faithgiant_Ps91 My S model 2009 Altima has the manual climate control and the compressor on mine has a mechanically controlled valve (no wire). It just works off system pressures. Still variable displacement. Unfortunately on mine it is located facing the engine block, so if I replace it I may likely have to remove the compressor completely. My compressor model: Valeo DCS171C.
@@scottcampbell1552 Honestly, I believe mine is facing the same way as yours. I actually took mine to a popular mechanic in my area and found out that I just didn't have enough freon available in the system, so they did vacuum and recharge, and now I have perfectly cold air. So I didn't have to mess with the control valve after all.
So would pag
Oil have to be added to the compressor after replacing the expansion valve? I also have a leak at the high pressure line going to the condenser I was going to replace the o rings what do you recommend?
You shouldn't lose enough oil to worry about needing to add oil.
They was gonna charge my sister 1200 bucks to do that thanks a lot bro
My 2015 Nissan Altima AC is blowing out hot air when the car is on I checked the Freon pressure and it’s good doesn’t need any but still blowing out hot air
See if the compressor is coming on if it is check to see if the low side line is getting cold, if it isn't it could be your control valve. Watch this video to see if the computer is able to control the compressor clutch. ruclips.net/video/SA_IE7WivHU/видео.html
Also here is a video on a problem I found on the nissan. ruclips.net/video/K5W9ZXulUBk/видео.html
The passanger side of the car AC seems to be coming out cold but the driver side starts coming out a bit warm doesn’t get as cold if anything still feels sort of warm compared to passanger side then they just get warm of both sides I can hear the AC compressor switching on and off when I switch the AC on and off

Bottom back of the compressor but if you don't have automatic climate control you won't have it.

@@litzm3006 It might be the compressor but you can get an expansion valve for $10.00. If you do change it I have a video changing it.
@@737mechanic Thank you for the quick response back I will let you know how it turns out. Going to try to change expansion valve
I don’t have a control valve in that position. Put it in a lift to confirm. How would I go about changing mine?
So your car must have manual A/C, only the cars with automatic A/C have a control valve.
I'm buggin' over here because my AC compressor does NOT have a control solenoid valve
The control valves are not on manual A/C systems. So your car must not be a SV and must not have automatic A/C.
@737mechanic Correct. It's a SR. Def a manual. No digital temp controls. Interesting. I'll look Into the difference between a compressor for a manual and a compressor for an automatic ac systems Thank you.
This fixed my problem but it came back
And the dealer said it could be the ambient tempature sensors
You said your A/C is blowing cold air? What is the problem you are having?
What does good valve read in resistance across the 2 terminals. I'd like to measure before I replace?
Around 26 ohms, but remember even if the resistance is good the valve could still be stuck.
Porque el compresor de mi nissan altima 2015 2.5 no trae esa válvula
Can I remove the AC compressor control valve without draining the freon? I was just planning on using one of those canned freon bottles to add some refrigerant. Would that work?
No, You need to empty the system first.
@@737mechanicwhat happens if you don't
@@herc1319 It will empty itself as soon as you get the clip removed.
Chief, I made sure there is zero pressure in the system but the damn CCV is seized in the compressor due to rust, the c ring was pretty badly rusted to. Any ideas on how to get it out?
Keep it sprayed with a penetrant oil and keep working it until it breaks free.
@@737mechanic worked like a fucking charm man, with the new one, I’m assuming it’ll hold itself down once I put the clamp ring and pressurize the system again, yea?
Btw, you’re a godsend
@@737mechanic rip, didn’t work :(
Pressures read good, compressor fine, refrigerant is at the right level and new. But it’s still blowing hot. Thanks for helping anyways chief, I appreciate the wisdom

I don't think there is any way to clean it and reinstall. just buy another one online. You can get them for as little as 20 dollars.
Bro .. really helpful 👍
The base model S does not have a control valve. Only the SL and SV models do.
Any tips to fix the warm air blowing for the Model S?
@@jonahgarcia6422 let me know if you found any
That very clear.Thanks
Hello there thanks for the video the compressor control valve in my altima is different my car is 2013 v6 3.5 sv model the difference is that your control valve has the sliver part mine does not do u know where i can find the part many thanks
So am I draining the system of it's freon before removing valve? Then re charging it after?
I'm trying to do any and everything before I break down and buy a new compressor to put it myself .. sucks being broke
@@christopherhitchens1502 Yes, drain the system before removing the valve. I have another video replacing the expansion valve, another cause of not cooling. If your compressor is coming on and it is not cooling then either of these can be the cause. The control valve is #1 but the expansion valve is 2nd. If your compressor clutch is NOT coming on, these will not be your problem.
@@737mechanic ok cool, thank you
What does that control valve do cause our ac is working but its blowing cold air like it should
The control valve keeps the pressures balanced in the system, unlike systems without a control valve where the compressor cycles on and off all the time in a control valve system the compressor rarely cycles, the control valve will vary the displacement of the compressor instead of engaging and disengaging the clutch.
I have the 2015 pathfinder 3.5
I’m having a hard time disconnecting the connector from the old valve, any suggestions?
Make sure the tab is disengaged and pull and it should come.
My Nissan Altima SL 2013 A/C FIRST would sometimes not cool properly so I was going to replace the Compressor Control valve -- but NOW i see the clutch does not engage and the LOW pressure line gets very hot even with all A/C controls turned off. QUESTION: Will a failed Control valve prevent the clutch from engaging or does it ONLY cause off and on cooling. If not then maybe I have a wiring / connector problem like you show on one of your other videos. ALSO -- What would cause the Low pressure line to get very hot when compressor is not engaging and all cabin switches are off? IF I replace the Control valve I will also replace the Expansion valve -- Thank you for your attention, all your videos are very helpful.
Hi, did you ever find a resolution to your a/c issue? Would you mind sharing what it was? Thx!
@@juliusmarkov8182 The A/C clutch was defective. It did not engage when it received power to do so. As I remember THIS A/C clutch on a 2013 Altima SL; has two wires. If you replace the clutch OR get a whole new compressor unit with a clutch - make sure it has a two wire connection (IF your original unit has two). I do not understand exactly why, some only have one wire - but the SL with automatic A/C is designed that way - there must be a reason, maybe the automatic feature. I however I now never use the automatic feature to control the A/C unit which the Altima SL has. IF you are having a problem check all relevant fuses first.

Hey did ur ac got cold at noon ?i tried this last year but i bought one from O'Reilly and it worked but today is too hot and its not working
I think ima go with the original one
Still working.
This must not be the case on a 2016 Nissan Altima S I ordered a valve and it is supposed to come in today but just got under car and do not see the valve and it is a Valeo 92600 32ATE.. how do you access the expansion valve?
Your car does not have a control valve. Here is a video on changing the expansion valve. ruclips.net/video/sH1yDllWlPg/видео.html
@@737mechanic thank you.. yes I see that... It sucks I thought it would be an easy fix. I guess Nissan caught wind of it and changed the compressor. Thank you for confirming
@@737mechanic Hey, I got the expansion valve out and I notice that there are orrings on the ends of the tubes but 2 orings came with the expansion valve the kit that I got from Rockauto has a but of orings But I know each tube gets an oring but when I took out the expansion valve I did not see where the other 2 orings go.
@@dallaspilotcar9293 You should have two between the expansion valve and the evaporator and two on the other side between the expansion valve and hose assembly. Make sure you remove the old ones.
Why on some cars like 2001 Nissan Maxima, the compressor control valve does not have a wire connection? How does it work then?
It has to have a wired connection.
@@737mechanic There are mechanically controlled control valves that do not use a wire. My 2009 Altima S has one. Manual AC. The mechanical control valve works to try and maintain suction pressure. The model # for the control valve listed for my Valeo compressor is RKX-RCV-037 (seems only one company makes it).
@@scottcampbell1552 Good info to know. Thanks.
Is it the same for the 2017 I know those interchange a lot of parts but if it's the same for a 17 and that might help my situation
I am not sure if 2017 is the same but if you look to see if it has a control valve it should be the same.
Would you be able to explain in a video step by step how to identify the cause of my ac not working. I want changing the compressor to be the last thing. I have a 2014 sv Altima. Ac engages but will barely cool. Once it’s running the air will be less warm but not cold. Almost like a warm fan
Without hooking gauges to it I can't but I can say that if the compressor is engaging then I would change both the compressor control valve and expansion valve.
Hey I took off the clamp but my valve won’t come out
Dig any debris from around the valve then grab it and work it slowly as you twist and pull.
Can someone answer my question i need help
My grand vitara jb420 have this kind of compressor, but it also have a magnetic clutch infront, so my ac mechanic is a little confuse because when the compressor kick on, it wont turn off when it reach the temp that we want, like other compressor, in my toyota camry the compressor kick on when i turn the ac on, and then off automatically when it reach the certain temp, is this kind of compressor with a control valve behind it doesnt turn of automatically? If it doesn’t, why it have a magnetic clutch then? My ac mechanic confuse so he bypass it with a modded thermostat to make the compressor automatic
The compressor will turn off if the pressure is too high or too low but this is a variable displacement compressor so when it is on the control valve varies the displacement instead of turning off and on all the time. If your compressor is engaged and turning but you do not have cold air it is most likely the control valve is bad.
@@737mechanic ok thanks for the information
From what I've found this only applies to the sv and sl models, the base and s models use a compressor that doesn't have a serviceable control valve. I have an s model and found this video so I bought the control valve, got under the car, and found there was no control valve to replace.
Yes you are correct. I should have mentioned that in the video. Although if the compressor is engaging but your A/C isn't getting cold the expansion valve is a high failure item.
ruclips.net/video/sH1yDllWlPg/видео.html
I ordered that valve and when I remove the old one I noticed that the connection was different,
How is it different? It should be the same.
@737mechanic the connection and valve in this 2013 altima are identical to the nissan sentra,
Hello. My mechanic just vacuumed and charged the a/c on my 2010 altima. It cools good. However my clutch does not stop turning as long as my a/c is on. It stops when I turn off the a/c. When I tested this, the temperature setting was on 50%, just at the middle, and it was evening so not too hot weather. I waited around 5-10 minutes and the clutch did not stop turning. It was cold in the car but not very cold. When I turned the temperature switch to max, the air from the vents went colder. So the a/c temperature control system (probably some kind of thermostat) works properly. The only problem is that the clutch does not stop turning which increases the a/c gas pressure too much so it leaks out of the system. What’s the problem? Also 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 or the clutch is engaged as long as the a/c is on?
So if your car has a CCV or compressor control valve the clutch will stay engaged almost 100 percent of the time. What it does is unloads the compressor when it does not need as much pressure and increase as it needs more.
If your system does not have a CCV then check to see if the low-pressure switch is stuck when would keep the compressor engaged.
@@737mechanic Can I check the pressure switch without emptying the system?
@@MC-ph7gr Sometimes with the sytem running you can tap on it with a screwdriver or something and it unstick it if it is stuck.
My aircon is ok for a while, then it fades to warm. If I turn off the comp. for a while and/or rev to 6000 RPM, it goes cold again. Full of refridgerant.
It's an old BMW E39. Before I buy a new com., I'm going to try replacing the valve..
How did you relieve the pressure in the system? Do you press the nozzle where you recharge the ac?
I have a gauge manifold.
I'm having the exact same symptoms on my 2016 Sentra. Have you done this job on a Sentra before and is it more or less the same procedure?
As long as you can see your control valve and get to it, it should be the same procedure. Evacuate the system and pull the control valve out and install the new one.
Thanks for the vid very helpful
Question my 2014 Nissan Altima 2.4
I put Freon and ac clutch kick on and it’s on all the time what I see on idle blows hot air when I give gas like 3000 rpm blows cold any idea
Thanks and God bless you
Could be a stuck expansion valve.
Great videos, just what I needed. 2014 Sentra. I did the check from the other video and do hear 5 clicks from the compressor, but. Down below I see you tell someone to be sure the clicks are from the compressor clutch, not the compressor relay. Is the relay on the compressor? My clutch won't engage at all when running. I'm hoping the refrigerant is just depleted. Thanks.
The relay is in the IPDM, the clutch should be much louder than the relay. If you hear clicking from the clutch area then that is probably the clutch so you should be good as far as the clutch, so you may be right about the refrigerant being low.
@@737mechanic My bad. I just checked it out. the clutch does engage, so I'm going to get some r-134 and hopefully get it working better. I don't know how many more 90 degree days we have left in the Northeast, but it's still good to have. Good stuff, by the way, your videos. Us back yard hacks need videos like yours.
will this work for v6 3.5 model?
Yes if you have the SV ot the automatic climate control.
Hey bro, my old valve won't come out, it's super hardened there. Any ideas on how I can take it out?
Make sure the snap ring is removed and try using a couple flat blade screwdrivers and or pliers and twist and pry. it should finally come.
Wondering if you ever got it out? Mine won't budge. The plastic tab broke off so I have nothing to grab. I even drilled a hole and put a sheetemetal screw into it to help pry it out. Drilled several holes to get heavy needle nose pliers in to pull it out. Here I sit, waiting on my new compressor.
Is there two separate sensor switches? For low and high side? Asking for a SRX 2011.
Hello sir I have 2015 nissan sentra and when I'm driving I smell ac gas inside and later my ac is gone do you think. my leak is in expansion valve or evaporator?
Could be either one. I would replace the expansion valve first because they are as cheap as $10.00 and if that doesn't fix it the evaporator would be the problem.
Do i have to take out the refrigerant to evacuate the system or is that separate?
Yes, you will need to take out the refrigerant first.
@@737mechanic ok after i do that i should be ok right? Like there wont be pressure built up anymore?
My 2014 nissan altima doesn’t have that. Its the Valeo ac compressor that is installed on mine.
Only Altima's with auto HVAC have the control valve.
didn't work for me, i have a Nissan Altima 2015 sv the old valve got is stuck in the compressor, can't remove it. Guess you can take your chances doing this job. Ordering a new compressor. Thanks for the video though.
So you took the snap ring off and you couldn't get the valve out?
Was the compressor kicking on before you changed the part out? My compressor doesn't come on at all.
Yes the compressor should still come on even if the control valve is bad. You have another problem. Do this test and see if you hear the compressor clutch engages. ruclips.net/video/SA_IE7WivHU/видео.html
I have a 2014 Altima S model. It doesn't have a control valve on the compressor.
It blows cool air after picking up speed. The compressor clicks on and off. The low side pressure was at 70psi.
Thoughts?
Compressor may be bad if the low side only gets down to 70psi. It should be between 30 and 40 when the compressor is running. You also need to change the expansion valve if you change the compressor.
@@737mechanic would it be worth it to replace the expansion valve first?
@@1987mosdef You could try that, you can get an expansion valve for about 10 dollars online.

So, now my AC has stopped working and blows warm/hot air all of the time. Is the expansion valve clogged or would it be something else?

Expansion valve is bad.
Replaced control valve, replaced Expansion Valve also. In another video you have, I performed the compressor clutch test. I did here the clutch engage 5 times so I know it has power. With the car on the compressor does not come on at all. Possible a pressure switch not closed ?
Possible my $15 Control valve from China is bad?
With the car running does the compressor engage? If so feel the lines and see if the low side is cold. If the compressor is engaging and staying engaged when the car is running then the pressure switch is fine. It could be the control valve even though you installed a new one. You really need to put gauges on it and see what the pressures are.
My gouges read 90 psi both high & low side with the car running. Is it possible to by pass or jumper the control valve ?
It's not the control valve, the compressor should still come on even with a bad control valve. If the compressor isn't coming on it could be the pressure switch but keep in mind the compressor connector is a high failure item. I have another video of troubleshooting and fixing the connector because of the same problem you are having. Make sure the clicking you hear when you do the self-test is the compressor and not the compressor relay.
Checked all wire harnesses gouges hooked up, car running. Low side 89 psi high side 95

So my 2016 Altima stop blowing cold air when the car isn't moving as soon as I put some gas on it it star to blow cold air what do u think might be my problem?
Check to see if your fan is blowing, if so it could simply be low on refrigerant.
Also this video shows how to perform a IPDM self test which will ops check your fans and compressor. ruclips.net/video/SA_IE7WivHU/видео.html
Note to self. Relieve the pressure in the system. I say that as I sit in the emergency room with a forehead now missing a chunk thanks to a sensor lol
Sorry to your injury... I just replaced the compressor value from my altima 2013 and realize your injury and avoid it. I used a vice grip to hold on the valve and made sure an arm length distance from valve. There were so much pressure and fluid coming out that I was shock and surprised. Sorry again...
I have a 2013 nissan altima and I bought a brand new compressor. They put freon in and the compressor isn't turning on. They checked all the fuses they said. Would you know what the problem is?

Hi there! Is this Valve a part of the compressor? I have ordered a low mileage used compressor but I couldn't find this Valve on the actual compressor that I ordered. Appreciate your timely reply to help me get out of this jam before it's too late.
It is part of the compressor but if you do not have the auto climate controls yours will not have one.
@@737mechanic Thank you. I did some research since. The base and S model don't have it , but the SL and SR models do. It makes sense. You alerted me to it though because a lot of videos just didn't say it is a part of the compressor. I have a 2015 high mileage Altima. It Just cannot handel over 100 degree heat in Arizona but ok in the 90s. Should I definitely get a dryer to go with my used but low mileage compressor or leave the good original dryer unchanged?
@@cpan2552 The dryer is higher recommended If the compressor has created metal shrapnel of any kind most of it will be in the dryer. I have changed A/C components before without changing the dryer but it is a risk.
Hello brother can you help me please
I have Altima 2015
When the car is stop coming hot ,,
When I’m driving come cold
The gas is not deficient
??
What is problem?
Sounds like it is a little low on refrigerant, or the cooling fan isn't working correctly.
@@737mechanic I check everything is ok but the Pressure of compressor is 80
@@mohameedali4283 with the car running and the compressor engaged, the pressures should be about 25 to 35PSI on the low side and about 175 to 250 PSI on the hi side.
@@737mechanic when the car running its 80 psi 😢
The sensor make this problem?!?
I did this to my wife car and also changed the expansion valve compressor does kick in but the air is not cold
What are the pressures?
Low- 30-35 high-120-130
And of course after replacing goes to part I did Evacuate the system with a vacuum pump for almost two hours and then I recharge the system but for whatever reason it was only sucking in about 12 oz
@@ClaudBol the high side is a little low, when you feel the low side line does it feel cold at all?
Just I bit ,I wouldn't say it's cold but cool
God bless you for this! Just today....did this on my 2014 that the ac has been out for 3 years, was told by a Nissan dealer it needed a complete AC overhaul for over $2000 three years ago. The control valve is all I needed....$79 for the part...$202 for labor. Under $300 and Ive got air!! THANK YOU.
I love hearing stories like yours. Glad you have cold air.
@@737mechanic Man , I SUFFERED for no reason, because Nissan dealership tried to bamboozle me. Ill never buy another one.
I'm having the same problem with my 2014 Altima. I got the same $2K estimate from my mechanic. By the grace of God I found a thread about replacing the compressor control valve. I ordered the part on Ebay, it arrived today. I will be taking the part to the mechanic & showing this video to him first thing tomorrow morning. I'm so excited to see the look on their faces! Saving money makes me happy 😄 Plus I'm excited about getting cold, consistent air flow in this crazy TX heat! 🙌
Only if the control valve for the 2017 Nissan Altima was that simple.
I gotta ask why do you say this? Because I have a 2017 and was about to tackle this job. Something I should know?
If your car is a base (ie. No letter after the 2.5s), then the vehicle does not have a compressor control valve. I found that out the hard way after four hours of looking over and under the hood.
@@beeemdee_ ah ok, was a little worried there was something else lol. I have the SV, so hopefully it shouldn't be too hard. I understand the frustration tho
No problem. You will see the valve as you jack the car up. Make sure you have the tools to do the job and have fun doing so.
How do you diagnose those parts? Or is it a replace and hope its that type of deal?
With gauges connected I watch the pressures and see what they do when I turn the A/C on and off. The expansion valve and control valve can have similar symptoms but the control valve is a high failure item and since any time you evacuate the system they recommend replacing the expansion valve I would replace both to be on the safe side.
I didn’t know this whole time Hank from Breaking Bad was the one fixing that car 🤯
You have a good ear.
I don't see the compressor control valve attached on my Nissan Maxima. Is it another type of a compressor?
Only some Nissans with automatic A/C has them. If yours doesn't have it you are lucky.
Where can I find a control compressor valve like this for a 2013 Altima S?
Have a 2013 Altima S, AC turns on but air remains warm, any idea?
First make sure your car has a control valve. If it does you can order one from Amazon.
@@737mechanic and if it does not, what can I do to get the AC back to being cold?
@@chriskerio Watch this video and see if it helps. ruclips.net/video/K5W9ZXulUBk/видео.html
Please so my Compressor is come on and turning off could this be the reason
If your compressor is coming on and staying on long enough so it should get cold then it could be this control valve. It could also be the expansion valve but the control valve is easy to change so might be worth a change.
I am curious what you think might be an issue when the low side is 70 psi and high side is 150 psi on a 85° day? Compressor runs all the time. Solenoid or expansion valve?
I would think control valve first but I would do both since both are cheap.
@@737mechanic thanks, also I was watching the pressures on the gauge at idle and witnessed the high side drop to to 90 and low side increase a little. But never saw the low side go below 70.
Do not see the control valve listed on the 4 cyl but pretty sure I saw the harness for it.
@@bobspreng611 if I am correct I think only the sv model and cars with auto HVAC are the ones with the control valve.
@@737mechanic it is a SV, thank you so much for replying. Very kind of you!!!
I’m getting the same readings on my Nissan Sentra.. did you solve the problem?
737mechanic Do you need to discharge the compressor before removing the valve?
Yes
How would that be done? 🧐
@@briansanders4558 you hook a gauge set to it and you use s recovery machine.
@@737mechanic thanks, will try and hope this fixes my AC problems .
My compressor doesn’t look like that underneath!!! Can u help me out??
If you don't have automatic climate controls you will not have a control valve. Is your compressor engaging at all?
@@737mechanic it has an auto button on the panel where the ac button is at, btw it’s a 2008 Altima 4 cylinder
@@Jigga-ke4gb What is it doing?
@@737mechanic I have a 2012 Altima. How do I know if I have automatic climate controls?
But im not getting a check engine light
Can I do this without emptying out the system?
No. You will need to empty the system.
@@737mechanic what would happen if I just replace it without empty it out first?
@@gustavoalcala1282 when you remove the snap ring it will blow out under force. It would not be a good thing.
@@737mechanic I just had a supposedly mechanic do that to my Nissan car and want to know what to do? He took the value off with out draining the system..I don’t know what to do? And now do I need a new compressor or will the new control value still go in?
@@kassandrasaldana6145 You should be able to install a new one and everything should be good.
So you evacuate and recharge the system after you replace the valve?
You evacuate it before you remove the valve then you recharge it after replacing the valve.
What would you say is a fair price to pay a shop to replace this ? I just moved to a new state so my family and familiar mechanic I would usually go to is 14 hours away. I already paid for a AC tune up before my move which didnt fix it so I feel like this is most likely the solution. In the early morning/late night when its cool it blows cold air but i moved to texas so the moment it gets 85+ degrees it blows out hot air.
My guess would be about 250.00 or so. They have to evacuate the system replace the valve then recharge it.
Was your ac compressor still kicking on? When it was bas
Yes
WHERE DID YOU GET THE PART? Will it work on a V6 Maxima???
amzn.to/3wkUZIW
Does this also apply to Nissan pathfinder 2014? Where do I find the ac compressor valve for pathfinder 2014? Same issue with the Ac. Have been given quote of $1700 cad.
The control valve will always be on the compressor. I am not sure if the pathfinder has one or not.
