Thank you, I just changed one on our 2018 armada, mounting is just a touch different but same 4 bolts and couldn’t of been easier, thx for the video it gave me confidence to do it myself and we saved prob $700, and only took 20 min to do.
Having the sagging problem in my 2015 QX80. I found the air shocks for $465 total and getting the back leveling sensor Fri for $200. I plan to get the compressor in a few weeks. Start sagging about 3 weeks ago. This is the only helpful video online. Thank you very much and GOD BLESS YOU.
@nocanndo16 How did your installation go? My wife has the same 2015 QX80. Sags in the back. I replaced the air compressor and both sensors and it's still not working. The compressor kicks on but no movement, the frame is about an inch from the top of the tire.
Jordan... STRONG WORK! Of all of the how to videos for this air suspension system, you provided the only guidance on the air filter piece that embeds into the frame. I tried to take it out, but ended up pushing it in, because I couldn't get the locking clips depressed for a smooth removal. I figure it'll bounce itself out of the end. The compressor was a wicked easy fix. It took me longer to ensure a safe jack support placement and fumbling around with socket sizes, then it did to effect the switcheroo. With my Arnott air shocks, new axel, new lower control arms, et al, I am stoked to hitch up and pull my camping trailer. Thank you for your simple video; I'll be posting it to the forum momentarily.
Thanks … was trying to figure out how to unplug that top hose , didn’t want to break it because I couldn’t see the back or how it clips , thanks .. totally helpful .
@@agray240 I have seen other youtubes where a test is performed in comparison w/a Denali, both pulling a heavy tongue-weight trailer up a Colorado Continental divide mountain pass. There is visual of the rear susp. NOT riding at the same height as an UNloaded...heavy weight causes some rear "sag", the riding height is somewhat lower.
Hey thanks, gave me confidence that I can fix this myself or at least be educated about it when talking to my mechanic. Holler at me if you ever want to start producing your own professional how-to videos 😉. Thanks again!
One additional thing that a person should do when installing a replacement pump. If you look at the supply hose, which plugs into the frame, it has a screen filter on that white fitting that pushes into the frame. While this filter is supposed to keep dust and other dirty air out of the compressor, I removed the old filter and used a Dewalt air compressor and an air gun and blew all the nastiness out of the frame rail. If you take a look at this frame rail, it is open at both ends (front and rear of the vehicle) and has holes in the frame all along the length. When I blew out the frame, a bunch of dust came out of the frame rail. While this won't prevent dust from getting back in, I believe blowing out existing dust inside the frame rail should assist with preventing dust and other bad air from entering the new Armada suspension leveling compressor. When I removed my old compressor, I tried taking it apart to see if it could be fixed, but discovered quickly that the old compressor pump and motor were filthy, leaving me with the impression that the failure of these units are likely more to do with dust and other dirt getting into the unit and leading to failure. By blowing out the rails with an air gun as an extra step, my thinking is that it will help to keep the new levelling compressor from failing early. It took about 10 years for the original compressor to fail. I hope that by blowing out the frame rail, that I will get at least another 10 years with the new unit. One last thing, Jordan ... thanks for the video, but when you plugged in the air bag hoses into the new compressor unit, did they go in all the way? I'm talking about the spot on the new levelling compressor where the two air bag hoses plug in at the orange fitting. My hoses didn't push in all the way, and it looks like this may be the case with yours as well. You can see this on your video at time-stamp 3:05 into the video. I have about 1/8" that I feel the air bag hoses can go in further, but it feels like they have bottomed out and I don't want to apply any additional force trying to push them in.
I have a 2017....i was checking fuses and i noticed the FL30 amp fuse was blown....i am running an aftermarket compressor as oem went out 3 years ago or so i thought at the time. Compressor isnt kicking on and I just had to replace tires and they both have negative camber slanting inward at the top. Would this FL30 fuse (its pink square fuse with clear top) be the issue and would it self correct the camber or would i have to get it aligned again as it was just aligned yesterday. Im lost atm. Thx!
Hello Jordan can you explain to me how to test for power going in or out. My compressor isn’t coming on. I bought a new level sensor and my bags are still low. All fuses are good.
Any recommendations on how to reset the system without stopping the car? Install a jumper switch to a fuse or relay? The system losses pressure after an hour or so and I would like to be able to have the compressor top off the pressure to maintain height. I realize there must be a slow leak somewhere but it appears that they all leak to some degree.
My ride fills up about every hour or so as well. It will slowly loose air then fill back accordingly. The sensor that controls it is the leveling sensor. You would need to bypass it by tapping before your relay (I think). It is possible. But honestly it’s just meant to give extra support when pulling or when additional people are in the back. I think i would not be worth your time. I tried researching some forums for you but there isn’t much. I would start with relay tho. Good luck.
Great info, changed both from dealer, new bags, new sensor and new compressor. Check suspension light came on, cant get it to turn off. Compressor wont come on because of it im assuming. Any tips?
Mario Lopez hmm 2 possibilities 1. Disconnect the relay switch then the battery (the one at the beginning of the video) then reconnect battery then relay switch. This will attempt to reset the system. 2. Take it to autozone. Have them clear the code. Then see if that kicks on your compressor after the light comes off.
Jordan, do you have any experience with the system loosing pressure over the drive time and the system not continually keeping the truck at the proper ride height? My shocks are new and I replaced my air hoses. My next guess would either be a leaky compressor or maybe a half bad relay under the hood. I have also heard that there is another brain box for the air suspension behind some panels behind the passenger second row seat on the driver side.
Eric Hasz my own guess would be a leak in the bags? Have you changed out the bags before? I don’t think it would be from a faulty relay switch. I do agree with a malfunction in the compressor. Pressure from the bags pushing air back out of the compressor due to a leak somewhere causing it to never be level. Another trick I have heard is get about three people to sit in the back around 500 lbs. let the compressor kick on all the way. Turn the car off and let the leveling system calibrate itself. Kinda like letting your phone battery die completely to recalibrate the battery. Lastly are your air hoses placed in the two holes correctly?
Thanks for the quick reply. I don’t really have an issue with it being the same level on both sides. I did change the bags out. Also yes the hoses are in the correct holes. Mine is more of an issue with it not staying inflated during the drive. I let it fully inflate before I leave and by the time I get 20 mins down the road I am almost riding on the bump stops. I let it air up this morning and turned it back off. Just went and checked and the bags are completely deflated. I’m thinking what you are, somewhere the back pressure is leaking out of the compressor
Eric Hasz It sounds like the compressor itself after your last reply. Sounds like it is leaking somewhere in the lines. Once pressure is in the system, it should remajn there unless the system tells the compressor to get rid of the air. I would double check again for leaks at the fittings. Where the lines connect to the shocks themselves would be most common. I missed the part where you emphasized while driving my bad. That makes me more sure your leaking air. Either at the bags or within the compressor.
@@DallasChisholm it did for a little bit. But the new shocks kept bleeding off too. Eventually it all stopped working. I switched it over to conventional spring and shock. Got a kit off of rock auto. The springs are much stiffer than the stock ones. Helps with light towing.
Superb video! So I have a 08 Armada and I hear the compressor kick on at start up and throughout me driving around town it turns on all the time. I’m assuming there’s a leak somewhere which caused the system to air back up. I don’t see any visible sagging… yet. Any suggestions on how to go about finding the air leak?
@@jhoff2488 hey sorry for the delay. Yea I checked the bags and lines out and there is no leaks. I ended up going to the local junk yard and pulled two bags from an QX56 with low miles. Just in case. Right now, I’m having issues with my A/C. I got this weird clicking noise by the glove box. Sometimes when I turn on rear heat/cold in the back, I’ll hear it in the clicking on the back also.
Your AC Problems sounds like blower resistor. Easy fix. Part is at any auto store. Mine did this also. You just have to take off glove box to fix. Lots of videos on it.
As for the relay to tell if it's bad. Do you disconnect the switch and then start the vehicle? If it kicks on it's the relay? Can you clarify on that please.
Unfortunately not. At least not that I am aware of. I just looked at the manual and the only way to bypass is the leveling sensor. Honestly trial and error. You could plug the harness into the 4WD relay and see if it kicks on. The relay works as a switch to turn the pressure sensor on (leveling sensor). Unplugging it would give that sensor no power. Therefor nothing would happen. Worst case buy a relay and change it. It’s 15$ and it’s never bad to have a new one.
Jordan I just wanted to clear up what you were saying at the start of the video. How to check the relay, you said remove the bolts and harness and replug it in and then turn it on? I'm confused on how to turn it on or what you meant? Thanks
Fernando Aguilar okay so I just talked about replacing it. I don’t know to check to see if the solenoid is burned out. The only way to check is to replace it. They cost like 25 dollars at autozone. If you replace and it turns on then it was the solenoid. Now to rule out if it’s the air compressor or not you can override the air compressor but that is located under the rig. That’s the part in the video where I talk about using three clothes pins and touching them together. If you did that and the air compressor kicked on you know it either has to be the leveling sensor or some other electrical problem. If yours isn’t working 75% chance your air compressor is bad. 25% chance it’s the solenoid under the hood. Hope this helps.
You can put 12v charge to the smaller plug side of the relay and if you hear it clicks when you the charge on it then that means the relay is still working
Jordan, I'm considering putting on some non-air shocks. Can it be done? I figured that I''d go with the Rancho 9000's. This way if I was doing some hauling, I could stiffen up the shocks. I don't know if it's just that simple though.
1. Are the hoses connect fully in the compressor? 2. If the answer is yes. Are you sure air is not blowing out the bags? Usually the compressor makes a loud sound. Pretty annoying. If this is the sound your referring too. That’s normal.
2012 Armada Platinum here. Relay good. Brand new height sensor. Compressor kicks on, but only when I disconnect it from the Height Sensor right now. I'm thinking something to do with the leaky bags in the struts? I'm am about 3 inch clearance tire to wheel well on both sides like you noted you had before your fix. Could there be something faulty with the compressor as well? It does kick on, but like I said only when I disconnect the height sensor, and only runs for about 15 seconds. Would not kick on though doing your 3 paperclip method. Thoughts?
So my thought is your height sensor. For some reason the setting on it (screw) may be off. So when connected your truck thinks your at the proper suspension height so the compressor doesn’t kick on. I would mess around with that nut on the sensor and see if there is any change. Am I making sense?
@@jhoff2488 Yup. I know exactly what piece you are talking about. I'll have to play around with it and see what's going on. The new one I put on came spaced out more stock than the old one was. (old one has like 2-3 threads showing, new one has 4-5 threads showing.) still may not be a enough though.
@@jhoff2488 So I just tested what you said and that right now seems to be exactly the reason. I actually disconnected the two pieces of the sensor and was moving the lever by hand. When I moved and held it up, the compressor would kick on, and when I moved it back level, it went off. Only problem is, the bags in my struts are leaking/faulty from wear, but I am changing those soon so I can update after that and see how it goes.
Your freaking on it my man. Nice stuff. Yeah update me. Make sure to wd40 the bolts and nuts. Will save you energy and frustration when removing your bags.
@@jhoff2488 Got a new issue now! Air suspension keeps filling up too high to about 38"-39", even after adjusting the leveling sensor. All are brand new. I manually move the leveling sensor arm and it will deflate accordingly, but some reason it won't when I reconnect to the arm. Any thoughts?
I am trying to undo the compressor electrical bracket to test it for power. I am having trouble getting it to separate. Do you remember how the harness comes apart? Thanks.
My air compressor only work with the scan tool or if I unplug the height level on driver side rear. As soon I connect the height sensor it goes deflated. Shocks holding fine. Please help.
Depends on how much. But yes. The rear of the vehicle wouldn’t have the support it normally does without the bags. The fact that it’s both wheels is likely from the lack of support. The little suspension it has without the bags is under a lot of load. This can pull the top of tires inward (physics). Air compressor should fix this.
My 2012 QX56 suspension lowers when vehicle is switched off. And raises when started. It wasn't like that before. What kind of air compressor issue could it be?
I would first start off finding the leak. Air is leaking from somewhere. 1. Where the hoses enter the air compressor. 2. Where the hoses enter the bags. 3. The bags themselves. Get yourself some water and soap and start spraying to find where it’s at. Your vehicle is only a 2012. Seems very odd that your bags would both be leaking. *found this Air ride systems have one inherent weakness no matter which manufacturer has created them. That weakness would be air leaks from the air bags, air lines used to pressurize them and solenoids that are used to inflate or deflate the air bags. It is very common for temperature to affect the the ability for the air lines and air bags to seal. When temperature drops, these lines and their seals contract creating small leaks. At least this is the most common thing that occurs. This sort of thing happens with evaporative emission systems as well.
Alex Valladares that’s a different question. Maybe look into a switch that controls your compressor rather than the leveling sensor? You would run a switch through the relay I believe. Or there may be away to mess with the leveling sensor. There is an arm that I was talking about in the video. The only thing I can think is messing with the nut on the arm to shorten it. Shortening it would make the arm not goes a far up and stop the compressor. Note: I have never done this but the concept makes sense. I can look at mine if you need me too. Honestly I would go with a switch tho.
My kicks on once for sure most times when I start it. A way you can test it is turn your vehicle on, open your trunk and have two people sit on the bumper. It should kick on with the additional weight.
@@jhoff2488 hmmm okay I don’t hear mine kick on often when I do it has a loud humming noise I thought it was abnormal. Maybe it isn’t but I don’t hear quite often every time I turn on my vehicle
@@hobbyist1001 it’s hit or miss man. The sound is annoying. It’s loud so what your hearing is most likely normal. If you hear straight air like an actual compressor somethings wrong. But the annoying buzz sound means it’s working. I think your fine if you hear it from time to time
I have a d2racing air suspension set up with just the basic dual switch control management.... my air compressor will not turn off anymore please help....
Mustafa Gak have you unplugged the solenoid under the hood and plug it back in to reset the system? If that doesn’t work I would lean towards the leveling sensor. Expensive little part. It may be tricking the system to think it’s never level and keeps telling the compressor to engage. When the compressor is on is it actually filling up your bags? If so I guarantee your bags blew due to air pressure which is causing your compressor to remain engaged. Air is leaking out as air is coming in. Hope this helps. Let me know.
@@jhoff2488 have not tried to unplug the solenoid under the hood that u mentioned or even the relay that's in the trunk but the air suspension kit came with a car I recently purchased everything was working well up untill earlier today... I have an on/off button for my compressor under the steering wheel that I used to turn the compressor on but it will no longer turn it off... unless I unplug my battery complely
@@jhoff2488 and the bags I dont think are blown as I can still use the control management to air up and down properly just the compressor that fills the tank will not turn off
@@jhoff2488 should just be the positive and ground wires for the compressor but I'm not sure as I still have yet to actually take the panel off but I will be doing all of that as soon as the sun comes back up
So I am pulling a camper 6000 pounds 510 tongue weight. Camper place would not let me leave with something out of my range and safety. The sag is too much in my opinion. Car place says everything is working like it should. But I can’t hear anything working. So any opinion I would appreciate it very much
@@jhoff2488 thanks man How has it been running? Any issues with it? Are you noticing any longer run Time? Is it worth the $ and or you recommend the OEM?
@@alikk99 no different in run time. Kicks off when it’s supposed to. It’s been two years since I’ve had it and zero problems. I use my armada a lot as well. So it has gotten lots of time.
@@jhoff2488 I took your advise and bypassed sensor with putting paper clips in. However I took a chance with trying that first before relays and soon as I put paper clips in compressor turned on. So ordered part from Nissan and what do you know !!! I was thinking maybe was a bad airbag too but when replaced that sensor airbags filled fine- I watched few other videos and seems like relay- compressor -height adjustment sensor or bad airbags were main factors.
Can you show me exactly how to disconnect the air pump pls I just replaced both of my airbags and the air compressor but now it seems like the air compressor is not working I have a 2014 qx80

I'm considering putting on some non-air shocks. Can it be done? I figured that I''d go with the Rancho 9000's. This way if I was doing some hauling, I could stiffen up the shocks. I don't know if it's just that simple though.
Great video. Can you share the link where you get the leveling sensor for $80? I only see $120! Thx!!!
David Lubin the one I saw online for 80$ is no longer there. I as well see them range from 120-144$. Sorry :/
Where do you see the sensor for 120.00?
Thanks
That piece makes a load blowing sound on mine, do I replace the relay or the compresor?
1. Are the hoses connect fully in the compressor?
2. If the answer is yes. Are you sure air is not blowing out the bags?
Usually the compressor makes a loud sound. Pretty annoying. If this is the sound your referring too. That’s normal.
Did I miss the part where you gave instructions on re-connecting the electric wires?
2012 Armada Platinum here. Relay good. Brand new height sensor. Compressor kicks on, but only when I disconnect it from the Height Sensor right now. I'm thinking something to do with the leaky bags in the struts? I'm am about 3 inch clearance tire to wheel well on both sides like you noted you had before your fix.
Could there be something faulty with the compressor as well? It does kick on, but like I said only when I disconnect the height sensor, and only runs for about 15 seconds. Would not kick on though doing your 3 paperclip method.
Thoughts?
So my thought is your height sensor. For some reason the setting on it (screw) may be off. So when connected your truck thinks your at the proper suspension height so the compressor doesn’t kick on. I would mess around with that nut on the sensor and see if there is any change. Am I making sense?
@@jhoff2488 Yup. I know exactly what piece you are talking about. I'll have to play around with it and see what's going on. The new one I put on came spaced out more stock than the old one was. (old one has like 2-3 threads showing, new one has 4-5 threads showing.) still may not be a enough though.
@@jhoff2488 So I just tested what you said and that right now seems to be exactly the reason. I actually disconnected the two pieces of the sensor and was moving the lever by hand. When I moved and held it up, the compressor would kick on, and when I moved it back level, it went off. Only problem is, the bags in my struts are leaking/faulty from wear, but I am changing those soon so I can update after that and see how it goes.
Your freaking on it my man. Nice stuff. Yeah update me. Make sure to wd40 the bolts and nuts. Will save you energy and frustration when removing your bags.
@@jhoff2488 Got a new issue now! Air suspension keeps filling up too high to about 38"-39", even after adjusting the leveling sensor. All are brand new. I manually move the leveling sensor arm and it will deflate accordingly, but some reason it won't when I reconnect to the arm. Any thoughts?
Will it shock me when i insert the paperclips?
I am trying to undo the compressor electrical bracket to test it for power. I am having trouble getting it to separate. Do you remember how the harness comes apart? Thanks.
It just should be a push button (to unlock) and pull.
I'm going to find a different location to put the air compressor because I need dual exhaust
My air compressor only work with the scan tool or if I unplug the height level on driver side rear. As soon I connect the height sensor it goes deflated. Shocks holding fine. Please help.
Those things got air ride? Damn..
Air leveling susp. sys. ( rear )...when loaded.
Can this cause both rear wheels getting slanted in slightly from the top ? I am in the process of buyin this compressor and doin it myself
Depends on how much. But yes. The rear of the vehicle wouldn’t have the support it normally does without the bags. The fact that it’s both wheels is likely from the lack of support. The little suspension it has without the bags is under a lot of load. This can pull the top of tires inward (physics). Air compressor should fix this.
Where did you purchase the leveling sensor for 80.00?
Im wondering the same thing. My nissan says $650 canadian.
I’ve already replaced the air compressor and both shocks and nothing . Tried the paper clips and nothing.
Which air compressor did you buy of Amazon?
Dorman 949-500 Air Suspension Compressor for Select Infiniti / Nissan Models www.amazon.com/dp/B01ID3W6YS/ref=cm_sw_r_cp_api_glt_fabc_0T8CW38MWFP9495VE5VR
My 2012 QX56 suspension lowers when vehicle is switched off. And raises when started. It wasn't like that before. What kind of air compressor issue could it be?
It shouldn’t lower on its own. This tells me you have a leak in your bags. Or an air hose coming out of your bags is not seated properly.
@@jhoff2488 how can I fix a leaky pipe connection to the struts
I would first start off finding the leak. Air is leaking from somewhere. 1. Where the hoses enter the air compressor. 2. Where the hoses enter the bags. 3. The bags themselves. Get yourself some water and soap and start spraying to find where it’s at.
Your vehicle is only a 2012. Seems very odd that your bags would both be leaking.
*found this
Air ride systems have one inherent weakness no matter which manufacturer has created them. That weakness would be air leaks from the air bags, air lines used to pressurize them and solenoids that are used to inflate or deflate the air bags. It is very common for temperature to affect the the ability for the air lines and air bags to seal. When temperature drops, these lines and their seals contract creating small leaks. At least this is the most common thing that occurs. This sort of thing happens with evaporative emission systems as well.
I replaced my shocks. Now my truck sits up way too high. Im trying to adjust it so its leveled not to raise up high, any tips???
Alex Valladares that’s a different question. Maybe look into a switch that controls your compressor rather than the leveling sensor? You would run a switch through the relay I believe.
Or there may be away to mess with the leveling sensor. There is an arm that I was talking about in the video. The only thing I can think is messing with the nut on the arm to shorten it. Shortening it would make the arm not goes a far up and stop the compressor. Note: I have never done this but the concept makes sense. I can look at mine if you need me too.
Honestly I would go with a switch tho.
The level sensor on the suspension needs to be adjusted. It’s a turnbuckle set up. Loosen the two nuts and adjust the linkage.
How often should you hear the air compressor kick on?
My kicks on once for sure most times when I start it. A way you can test it is turn your vehicle on, open your trunk and have two people sit on the bumper. It should kick on with the additional weight.
@@jhoff2488 hmmm okay I don’t hear mine kick on often when I do it has a loud humming noise I thought it was abnormal. Maybe it isn’t but I don’t hear quite often every time I turn on my vehicle
@@hobbyist1001 it’s hit or miss man. The sound is annoying. It’s loud so what your hearing is most likely normal. If you hear straight air like an actual compressor somethings wrong. But the annoying buzz sound means it’s working. I think your fine if you hear it from time to time
@@jhoff2488 sweet thank you and will definitely try to get 2-3 people to sit on the bumper to see if it’ll kick on
Does the same part fit the QX80 2014-15?
Which part? The compressor?
And I only think the QX56 models for Infiniti would be compatible. Your model is much newer. I looked it up and the 80 looks a lot different.
@@deangeloevans741 I believe the QX80 is different. SAme principal though. But the one I have I think would only work with QX56.
@@jhoff2488 ok thanks
I have a d2racing air suspension set up with just the basic dual switch control management.... my air compressor will not turn off anymore please help....
Mustafa Gak have you unplugged the solenoid under the hood and plug it back in to reset the system?
If that doesn’t work I would lean towards the leveling sensor. Expensive little part. It may be tricking the system to think it’s never level and keeps telling the compressor to engage.
When the compressor is on is it actually filling up your bags? If so I guarantee your bags blew due to air pressure which is causing your compressor to remain engaged. Air is leaking out as air is coming in.
Hope this helps. Let me know.
@@jhoff2488 have not tried to unplug the solenoid under the hood that u mentioned or even the relay that's in the trunk but the air suspension kit came with a car I recently purchased everything was working well up untill earlier today... I have an on/off button for my compressor under the steering wheel that I used to turn the compressor on but it will no longer turn it off... unless I unplug my battery complely
@@jhoff2488 and the bags I dont think are blown as I can still use the control management to air up and down properly just the compressor that fills the tank will not turn off
Mustafa Gak do you know what that switch is connect to?
@@jhoff2488 should just be the positive and ground wires for the compressor but I'm not sure as I still have yet to actually take the panel off but I will be doing all of that as soon as the sun comes back up
Can’t hear mine do you need to have weight on it to hear it work?
Sit in the back of the armada. Yes it needs to have some weight sometimes. If you sit in the back and you hear nothing. Something’s wrong.
So I am pulling a camper 6000 pounds 510 tongue weight. Camper place would not let me leave with something out of my range and safety. The sag is too much in my opinion. Car place says everything is working like it should. But I can’t hear anything working. So any opinion I would appreciate it very much

@@jhoff2488 thanks man
How has it been running? Any issues with it? Are you noticing any longer run Time? Is it worth the $ and or you recommend the OEM?
@@alikk99 no different in run time. Kicks off when it’s supposed to. It’s been two years since I’ve had it and zero problems. I use my armada a lot as well. So it has gotten lots of time.
Do I need to have this on a lift or jacked up? I don't want to get crushed bc that's what my wife would want and I'm trying not to let that happen lol
Not at all.
Is it bad to by pass ?
It’s no different then by passing a starter solenoid.
Isn’t there a fuse?
Greg yes under the hood I believe. Main fuse fox.

Found sensor was my problem thanks but was not 80$ !! 160$
Your correct. I don’t know why I thought 80. Glad you got it worked out.
@@jhoff2488 thank you!!!! 160 soo much better then I thought when I heared suspension I thought oh shit- your the man !
@@faithwalk007 if you don’t mind me asking how did you rule that it was the sensor that was out?
@@jhoff2488 I took your advise and bypassed sensor with putting paper clips in. However I took a chance with trying that first before relays and soon as I put paper clips in compressor turned on. So ordered part from Nissan and what do you know !!! I was thinking maybe was a bad airbag too but when replaced that sensor airbags filled fine-
I watched few other videos and seems like relay- compressor -height adjustment sensor or bad airbags were main factors.
@@faithwalk007 awesome man. Thanks for the feedback.
You could have easily just replaced with standard shocks and bypassed compressor completely. No need for it
Can you show me exactly how to disconnect the air pump pls I just replaced both of my airbags and the air compressor but now it seems like the air compressor is not working I have a 2014 qx80
