As a Honda dealership tech I always check fuses first. Saved me tons of time. Nothing wrong with diving in and figuring out a circuit expecially with a bad/wrong diagram ..that's where you gain knowledge and experience!!! great video Ivan
I worked in a Nissan, Subaru, GMC, Buick and CADILLAC dealership, they also sold Oldsmobile, and Suzuki's before Olds & Suzuki went away, anyhow out of all those different brands I always shook my head and wondered why Nissan used so many relays, and why their service information was so primitive. Good job!
Ha! Finally, I called one (to myself of course) before the end of the video. Only the minute or two in, an after hearing car wrecked and only one fan works I knew it was a fuse. Fuses often blow in wrecks. The body shop should have figured that out nearly instantly. Fuse box covers are labeled and easy to check. The video is great, though, as usual, for troubleshooting logic. It's what you have to do. Great work, as usual, Ivan.
johnaclark1 Did you see how buried that fuse box was? If there's no manual in the glove box it would waste the body techs time dicking around with something that's not his specialty.
Ivan I pulled up the wire schematics in Mitchell ProDemand b/c you had me curious & all the wiring schematics were there & color coded plus you can highlight the wires with a click of the mouse so easy to follow your wires. Looking forward to 7.8
I had the exact same problem back in summer, after fiddling with test lights, I came to the same conclusion - no power. It always helps to check the simple things first and as always, great use of test lights!
Had my door replaced after someone hit it while it was parked and the shop replaced it with the wrong door which had a different wiring harness for the airbag sensor so it wasn't even physically possible for them to plug the sensor back in so the airbag light was on so took it back and they tried to say the light was on when they got it. That was fun trying to get that fixed
On older vehicles I’ve had to go under the fuse box in the engine compartment and find the wire that either feeds the positive or grounds the negative of the relay that starts the cooling fans. I usually find most of the problems there. Either a break in the wire an open or a bad connection or the yucky green powder.
Same trouble with a Honda I worked on. The body shops just don't get it. Wires were still cut and several items were unplugged. The wiring harness was taped to the radiator support since the original retainer was broken.
I recently had a fan not working in my Trans Am. It uses a 3-relay system with a low speed and high speed setting. My motor turned out to be dead and there was a bunch of dirt chunks in it that looked like some small wasp nest. Got a replacement motor from the junkyard and good to go. Still can't figure out the high fuel trim on bank 1 though..
It looks like on low it runs the fans in series, using power from the fuse, but on high the drivers side fan is powered directly from the battery (non fused), I'm not sure I like that. It looks like the fan system operates like this: On High: Relays 1 & 2 supply non-fused power to Fan 1 & Relays 3 & 5 connect Fan 2 to ground. On Low: Relay 4 connects one set of windings in each motor in series. The fused power flows through 1 winding of Fan 2, through the contacts of Relay 4, through 1 winding of Fan 1 and to constant ground. I'm sure they had reason for this somewhat complex system, I wonder what it was, were they concerned about loosing all cooling with a blown fuse? Wouldn't an auto resetting circuit breaker be a better option?
great video Ivan. No wonder why body work is so expensive. Shops can't figure out a blown fuse and have to call an spacial is like Ivan to find it out..
Great fix and why the delay with the circuits especially for new cars.The makers should make it their business to have the necessary documentation available for the benefit of the owner.
As soon as I saw the title I thought Nissan hidden fuse box ! I have been there bought the T shirt the ones on the Nissan Note are even more hard to find mounted upside down below the battery,
I've seen bad things happen to electrical components mounted too close to the battery. But a fuse box or computer mounted UNDER the battery?? Recipe for disaster if you ask me...
I have same problem fan not working no warning lights on dash car seems to be working fine,how can i get to this fuse location? To check if it’s blown thank in advance.
One quick question. Could u link us to the AES wave kit u used. Thanks again!! Will b working on the Borshst pretty soon. Sorry for wrong spelling on that lol.
I had a Nissan once a Japanese local market car. The wire colours meant nothing. They even changed colours at the connectors. Furthermore all the fuses were marked in Japanese.
Just because the body shop did the repair doesn't mean they actually checked the fans if they worked. My wife's Elantra was smashed up a few years back, and the body shop just kept charging the new battery rather than check for a ground short. JD
A billion relays, one side has constant power, the other side has constant ground, "low mode" didn't work with a dead power feed... Sounds like an H-Bridge Series-Parallel setup. Want the fans slow? Series 'em together. Want 'em fast? Parallel those mothas. Kind of strange to see things done this way on a modern car, though!
I've been a Nissan tech for a while. they leave a LOT to be desired when doing electrical diagnosis. the diagrams are getting better on the newer models but I have access to those and I doubt the aftermarket does. serviceability yeah right......the 90's and early 2000's Nissans where the best. since getting in bed with Renault......not so much. I feel like I work at a Chrysler dealer with all the CVT issues we have. best product IMHO the Frontier solid truck.
I commend you man, for an extended diagnosis of this. But cmon, a fuse is the FIRST thing you check with something like this! I don't understand why you did the lengthy electrical testing first.
Brandon Friesen I'd say it must get old walking up to every car and checking fuses that aren't blown... and most of the time when you are called by a shop you kind of assume they've already done so.... he doesn't work for free so these guys just cost themselves... unless they can tack it onto insurance.
True it can be old, but the first thing you always check is fuses - even if you think someone else has checked them - and it dosn't take very long to do. Using a Voltmeter/Multimeter you can check all fuses in a couple of minutes. Never Assume. What would be better.... Checking fuses for a couple of minutes to rule them out and carry on, or start chasing your tail for an hour then checking the fuses and finding one blown? A lot of time and money can be saved.
***** Exactly. Don't even need an ammeter or anything. Just a simple test light to verify both ends of the fuse are receiving power. What I would've done is verify the fan doesn't run, check owners manual/online for fuse diagram, locate the affected fuse and see if it's blown. If it's not blown, you check to see if the fuse is having power on both ends. Then if so, I'd test the fan to see if that's receiving power, test the motor, etc. Easy stuff, he just complicated it too much. But still props to him. He just does it too textbook to the point of he wastes time
The whole process took like 20 minutes, including making the video! Please tell me exactly which part you think was a waste of time so I can improve for the next one...
This vehicle seems like a bear for serviceability - 5 non-serviceable relays to control 2 fans, no wiring colors on the wiring diagram, and a fusebox jammed in way down behind the headlight.. Remind me not to buy a Nissan Rogue, lol.
Renault influence on Nissan design and parts quality is not a good thing for Nissan's reputation. Also these secret hidden fuse boxes seem to be on most Nissan models the access to one in the video was actually good compared some Nissans.
My wife drives a 2010 Rogue and has over 180k miles on it. Still on the original CVT fluid. Granted those are mostly easy highway miles with no towing, but seems to be going strong!
Ivan, my sister bought a 2016 Rogue, when she was visiting i looked at the manufacture plate and seen it was manufactured by Renault-Samsung Motors in Korea. Not even a Nissan anymore.
Yes Nissan schematics are not the best. You have to check different sections of the service manual and add the wiring color by hand on a printed schematic.
should have tested them in "mono fan" mode, would have narrowed it down near instantly! clearly shows it having fans in series for dual low speed, why run a resistor when you can use both in series. on second glance, it's more complicated and could multi-step the speeds between fans. once again, mono-fan testing ;)
Most body shops are fantastic at body work. And if they 'see' it, then they know to replace it. Body work is a totally different beast then mechanical repair. Some can multi task, others will see this as a road block and call someone else in to finish it. So I wouldn't state the body shop cut any corners. Frankly their body work looked pretty good! Clearly electrical techs they aren't...
What an infuriating wiring diagram! Imagine how much time techs have wasted trying to figure out what is what with those vehicles. Unreal! What the hell is wrong with some of these manufacturers??? I'd NEVER buy a Nissan, and now I have yet another reason to add to my list ...
Negaton they are one of the busiest shops on the island. so what happens is that they would rather keep their guys taking care of more body work and let us come in and take care of the rest. just to give you an idea they handle and average of 45 cars a week in A 4 Bay shop
As a Honda dealership tech I always check fuses first. Saved me tons of time. Nothing wrong with diving in and figuring out a circuit expecially with a bad/wrong diagram ..that's where you gain knowledge and experience!!! great video Ivan
Ivan's approach gets the hard stuff consistently. Thanks for holding the camera in impossible positions and making us think. Great stuff!
I worked in a Nissan, Subaru, GMC, Buick and CADILLAC dealership, they also sold Oldsmobile, and Suzuki's before Olds & Suzuki went away, anyhow out of all those different brands I always shook my head and wondered why Nissan used so many relays, and why their service information was so primitive. Good job!
They just care about selling cars, not worried about the poor chaps who have to work on them, haha.
I knew the fix by some comments below but it's still good to watch and learn how you go about your process. We can all learn form that!
Ha! Finally, I called one (to myself of course) before the end of the video. Only the minute or two in, an after hearing car wrecked and only one fan works I knew it was a fuse. Fuses often blow in wrecks. The body shop should have figured that out nearly instantly. Fuse box covers are labeled and easy to check.

johnaclark1 Did you see how buried that fuse box was? If there's no manual in the glove box it would waste the body techs time dicking around with something that's not his specialty.
What a fabulously convenient place for Nissan to put the fuse block...AND to use some wacky non-standard type of fuse
Ivan I pulled up the wire schematics in Mitchell ProDemand b/c you had me curious & all the wiring schematics were there & color coded plus you can highlight the wires with a click of the mouse so easy to follow your wires. Looking forward to 7.8
hmmm I guess AllData does have 2015 so only 2 years behind :)
Nice step by step to find a fuse. I do like the diagnostics to get to the answer.
No guesswork :)
I had the exact same problem back in summer, after fiddling with test lights, I came to the same conclusion - no power. It always helps to check the simple things first and as always, great use of test lights!
Good video and the lighting is better than the last one.
Yeah can't beat the sun in terms of lighting!
Had my door replaced after someone hit it while it was parked and the shop replaced it with the wrong door which had a different wiring harness for the airbag sensor so it wasn't even physically possible for them to plug the sensor back in so the airbag light was on so took it back and they tried to say the light was on when they got it. That was fun trying to get that fixed
haha good one!
Nice job Ivan! Keep banging those cars out. Where the hell is Keith? Lol, you guys are awesome!
tankabbot22 I was watching from afar making sure he was earning that money lol
Nice job Ivan. Simple fix, in the end! Thanks!!

Nice vid man. Was probably just as quick doing the diagnosis as trying to find the fuses :)
lol I had no idea there was a fuse block wayyyy behind the headlight. Good thing my arms are skinny!
great video Ivan. No wonder why body work is so expensive. Shops can't figure out a blown fuse and have to call an spacial is like Ivan to find it out..
Did the aircon call the fans, instead of waiting for the engine to warm up?
was it not able to set a code because the fuse was blown?
I guess this fan system is still rather "dumb" in terms of not having sense circuits for fan speed like some other makes/models.
Great fix and why the delay with the circuits especially for new cars.The makers should make it their business to have the necessary documentation available for the benefit of the owner.

very well done Ivan thank you
I have same problem fan not working no warning lights on dash car seems to be working fine,how can i get to this fuse location? To check if it’s blown thank in advance.
I show it in the video 😁
@@PineHollowAutoDiagnostics can it be accessible even with headlights assembly in place engine in place I just couldn’t see it in my engine bay
You never give it the classic reach around like eric
Hey at least not on camera LMAO
such a classic move too
Anyone that does it properly, especially on camera, deserves a first place trophy
Can you do a scan tool review of launch vs others. Also a video of fuel trims wen you don't get % you get a AF ( lt trim) and AF (at trim)
Go to-- Wells Vehicle Electronics--on You Tube
The AFR Video is only 2 days old
I won a nice T-Shirt there answering questions
One quick question. Could u link us to the AES wave kit u used. Thanks again!! Will b working on the Borshst pretty soon. Sorry for wrong spelling on that lol.
posted in description. Let me know how the soup turns out Bill :)
motoYam82 hmmm just looked through the video at the time stamps. It would appear you were there one extra hour sir. Any excuse ? 😲😉
Hey that was a Bermuda Triangle time warp! Good thing I'm not on flat rate...would never last at a dealership :(
Hey now, no micromanaging! lol
Baxrok2 are you ready to come work with me for a day yet? pack a lunch cause there is no stopping
Ivan do I need the tablet you have to figure out which fuse is blown? My big fan isn’t spinning.
Thank you your videos are awesome...
I think 🤔 fan 1 is primary fan for typical cooling and other is ac cycle normally in front of compressor area (passenger side)
شكراً جزيلاً لكم أستاذ على هذه المعلومات
I had a Nissan once a Japanese local market car. The wire colours meant nothing. They even changed colours at the connectors. Furthermore all the fuses were marked in Japanese.
Morning , Can you share with me this diagram
Nice job man. Wow, nice convenient location for that fuse box..... Pffff! Not....
Good job Ivan, if it's possible can you give a link to your test lead kit sometime, would be much appreciated, great Video as always
www.aeswave.com/uTest-Advanced-Terminal-Test-Kit-p9467.html It's a great kit!!
The shiny core support was a dead giveaway that work was done. Manufacturers never waste clear under the hood.
Just because the body shop did the repair doesn't mean they actually checked the fans if they worked. My wife's Elantra was smashed up a few years back, and the body shop just kept charging the new battery rather than check for a ground short.
JD
sucks to get burned on a manifold. nice fix
Thanks for shearing this it was so helpful
lord knows that pos nissan needs both fans because of the pos cvt keeping the engine rpm so high
Nice work Ivan.
you're a great technician
Thanks for the video, have you ever thought about opening an Amazon store?
Thank you so much was helpful

Series 'em together. Want 'em fast? Parallel those mothas. Kind of strange to see things done this way on a modern car, though!
No wire colors, jeez what will they do next, I don’t think they want people working on their own cars.
yeah I know ,pressed wrong key,anyway great vids keep them coming,,
I've been a Nissan tech for a while. they leave a LOT to be desired when doing electrical diagnosis. the diagrams are getting better on the newer models but I have access to those and I doubt the aftermarket does. serviceability yeah right......the 90's and early 2000's Nissans where the best. since getting in bed with Renault......not so much.

nice
nice vid Ivan,which scanner is better the launch or the autel???
That Launch scanner looks like their top of the line model approx $4G's if I'm not mistaken. Quick too.
If they are both up to date, then probably Launch...but I still love my old Autel!
I commend you man, for an extended diagnosis of this. But cmon, a fuse is the FIRST thing you check with something like this! I don't understand why you did the lengthy electrical testing first.
Thank you for this comment. Now I know I dont need to watch the video.

Dam Ivan you're good. Was this practice or were you on the clock? Just wondering.
It was kind of an easy morning warmup to the mayhem that is the norm on that island...
Hey Ivan great video, btw I noticed your new laptop. Who makes it and how do you like it and would you recommend it.
It's not really a "laptop", more a tablet with docking station :) www.acer.com/ac/en/US/content/series/acerone10
toysareforboys Okay thank you.
It's only $200 at BestBuy so I won't cry if I drop it haha
This vehicle seems like a bear for serviceability - 5 non-serviceable relays to control 2 fans, no wiring colors on the wiring diagram, and a fusebox jammed in way down behind the headlight.. Remind me not to buy a Nissan Rogue, lol.
The first gen 2008-2012 are actually really good. These newer ones...disposable junk.

motoYam82 arent those known for the snowmobile transmission going bad all the time?

Ivan are you paid for your time and talent?
Ask Keith DeFazio lol
Gary Johnson I give him as many peanuts as he wants
OK, AND MAYBE A FROSTY MUG OF HIS ADULT BEVERAGE CHOICE
Actually I should be paying Keith for all this amazing education and experience but don't tell him that ;)

dang it why didn't I think of that? Great thought!
Nice!
Good job . The lesson to me is never buy a Nissan rogue.
Kind of a strange conclusion considering the problem stemmed from a body shop's cut corner during a collision repair, don't you think?
Most body shops are fantastic at body work. And if they 'see' it, then they know to replace it. Body work is a totally different beast then mechanical repair. Some can multi task, others will see this as a road block and call someone else in to finish it. So I wouldn't state the body shop cut any corners. Frankly their body work looked pretty good! Clearly electrical techs they aren't...
Adel Otb no nissan at all. especially new ones and their shit cvt transmission
👍👍👍
What an infuriating wiring diagram! Imagine how much time techs have wasted trying to figure out what is what with those vehicles. Unreal! What the hell is wrong with some of these manufacturers??? I'd NEVER buy a Nissan, and now I have yet another reason to add to my list ...
Dependable Auto Body is the name of the place but they mess up a radiator fan and can't even fix it? Thas a good joke.
They did a nice job on the body as far as I could tell...
Negaton they are one of the busiest shops on the island. so what happens is that they would rather keep their guys taking care of more body work and let us come in and take care of the rest. just to give you an idea they handle and average of 45 cars a week in A 4 Bay shop
That may be the case but I just find this quite quirky. Ivan is the man to get things done.
ivan back to basics ckech fuses first,,!!
LOL only if you "check" your spelling first! :)
How ignorant does Nissan gotta be to stuff that fuse block so far down. I guess serviceability is passé in 2016.
nice
