Man, thank you. It work. I rip off the Diode AND now The fan Is working. I love u
!!! For anyone wondering which pins those are - pin 2 from the top is ground and pin 4 (bottom pin) is 5V 0.3A. Anything between 3 and 5 volts should work just fine. As always, try not to short anything between those.
Ive used USB to run fan and it started spining for second but after that nothing happend. The fan doesnt work but the joycons chargin. Any ideas?
@@Lojalny then you've killed the fan, 5v 0.3a max. Normal USB has 5v 1a-2.1a
It's 1 negativ and 4 positiv for me. Working with two AA battery. If anyone looking for help see this comment check comment section i left a commentary with full procedure for newbies without any tools.
How about stop messing with it and pay this guy to fix it for you.
You are a champion - THANK-You, spent hours in that dam rabbit hole.. I used the left and right pins on the fan, didn't have a 2-3v power source so used the 5v power rail from a desktop computer power supply. Taped it once very quickly, fan didn't even spin with the battery removed and away it went. Both joycons charging and fan spin. Again THANK-you for sharing!

You're welcome by the way, I'm glad this little trick worked for you :)
Did you inject the power to the fan on the board or just to the fan outside the board? Should I inject the power to switch board?
@@mohammedaltameemi5342 you should do it while the fan is plugged in to the switch, that way it passes through to the mosfet and kicks it into life. It doesn't work every time but I've had good success with it:)
I learned a lot from just you talking. Been buying switches for cheap on eBay. They all work except a couple game readers and 2 joycons don’t connect . I’m gonna try this. Watched a fake repair vid of some one saying it’s the joycon ribbon needs replacing. That is not the fix. The switches that won’t charge the joycon also fan doesn’t spin. But I also have one that doesn’t connect or charge but fan works. Not sure how to fix that one. Thanks for these vids. Extremely helpful.
THANKS GOD THIS WORK ! SOLUTION FOR THE POOR DUDES HERE :
Pick two AA batteries (1.5v each). "Plug" them (one on top of the other, - from the first battery with the + from the other battery) scotch a cable on the positive left alone on the battery, scotch an OTHER cable to the negativ left alone on the battery. Then turns on your switch (everything plugged normally even the fan). With the cable positiv (from + side of battery) touch the pin 4 (bottom one), with the cable negativ (from - side of battery) touch the first pin (on top). The pins are the 4 very little metal bar visible where you plug the fan. FAN MUST BE NORMALLY PLUGGED ON SWITCH ON, or it wont work. That will relaunch the fan. I dont know by what sorcery but it's working ! Ovsly continue to work after you unplugged the battery
Hi, I'm facing the same problem and haven't really understood what you meant
I've got some batteries, scotch, but what do I do with it ? What kind of cable do I need ?
Thanks for this awesome video. The fan was not starting and replacing with a known good did not change it. I then probed the diode and cap next to it and they were both shorted. I then removed the diode and boom! The fan starting working like a champ! 2 thumbs up!
Great stuff, glad to help bud
Awsome video! had a switch that came in the store for no fan spin/no charge on JoyCon, and injected some voltage (3 volt) on the flex of the fan while the switch was On and bingo! started to work AND charge.. very weird but worked!!! thanks Mate!!!
I did exactly the same, injected 3v directly to the fan and it all started working perfectly fine again. Thank you
How did you inject the voltage?
@@imdanshort through a adjustable power supply, you put the black negative lead on any ground point or on the top 1st pin and the red positive wire on the 4th pin whilst the fan is still plugged in and it should sort it, I used 3v
@@54918ss Forgive my ignorance but will this be for AC or DC? I'm imagining DC
@@imdanshort you could probably use a spare 5v charger by cutting off the end and using the 2 wires to inject the voltage but it’s abit harder this way and you get a shock if your not careful. I wouldn’t Recommend it.
@@54918ss As it's low voltage I was thinking of using two AA batteries and touching wires to the vcc line
Can you please explain how you would do this with AA batteries?
Hello, thank you for your video.
After following your steps I have my fan working super fast when my switch is on. Do you know something about this kind of issue?
Removed diode (it was shorted) and fan is spinning :) It is my first Switch in my life and it is fixed !
Thanks for this video! Saved my switch! Although, I believe the 4th pin on the fan is for PWM to vary fan speeds.
I tried it and works. Thank you
I had that issue as well and I discovered it has to do with the fan inside the motherboard failing and thus the joycons don't charge like they're supposed to. Thankfully, I got it repaired.
How did you repair it
Just wanted to add that removing the diode alongside the fan connector resolved the issue! Naughty diode was shorting to ground both sides and doing the same to the nearby cap. This is no longer present in newer versions of the board.
Mine doesn’t have a diode and have the same problem
@@audisiojunior21 damn!
This worked for me too!!!
interesting many moons ago I replaced this diode on a switch to get it working.( noticed it was shorting to ground.)
i just tried this method of injecting voltages on another switch, and it's working aswell
happy
How did you fix it @@audisiojunior21
About a week and a half ago my switch started to over heat, and now the joycons won't charge. Is it the fan itself or the circuit that are the problem?
Glad to help bud, did you manage to get it fixed?
what did you use to inject the voltage. it can't bee the multimeter because those probes are still on the table, i'm trying to fix my sister's switch which has the same issue, and I don't have the material to inject the voltage needed.
I use a bench power supply but you might be able to do the same with a couple of AA batteries :)
@@TheCod3r is it hard to do with a battery? My switch has the same problem and a really thick your vid is very helpful but I lack the tools to inject the voltage needed
@@TheCod3r hey! can you explain how to inject the voltage with the AA battery please? Btw, excelen video!!
This is great! Worked for me on my Japanese switch.
I’m lost, how did you jump the fan ?
Really big thank you for creating this video. I have a Switch with no power going to the fan. I'm going to try a few things (both in your video and in the comments) and will report back. Great content in this. Please keep creating videos.
Sorry how do you solve that error?
my sons switch fan is not work and know that i see this video i dont think she joycons are charging either, did you figure out if they are related issues. thank you
I had the exact same issue, but putting 3.3V didn't work, cause there was a short, I had the version HAC-CPU-21 of the board and a diode near the fan pin was causing the issue, removing it solved my problem.
Thank you very much, but which pins should I inject the power in to? And which one the positive and which one is the negative? My switch is opened and I am waiting for your answer😊
@TheCod3r i have the same issue but there is on diode in that spot :/ is there another fix? Thanks
My Switch cpu-01 board also doesn't have the diode
my bad what is the tool that you used to jump it i dont wanna send it to get repaired
I experienced at the same time the same problem with 3 switchs... all of them wont charge both joycons with the official charger from nintendo , but charging great with 5v charger ! The problem is related with the TPS54560 (dc-dc converter) on the back side of the board top corner , in my case this one in short circuit on pin 1. But after replaced it , it burns one again ... I never connect the fan when doing theses experimentations so will give it a try
Yes the 5v DC-DC converter is a pretty common failure point on these. I believe it may be something related the the power management IC (M92T36). I personally think it may be an issue when using a 3rd party usb charger but I could be wrong
@@TheCod3r so if my fan is not coming on and Joycons don't charge, it might not be the fan but the board itself? I was hoping for an easy fix replacing the fan.
Thanks for the vid. Found it useful but still have a weird issue. Like your repair but in reverse. Replaced my dying fan, after I reassembled it fan is stuck at full speed and stays on while joycons are connected, even when unit is powered off. If I remove the joycons the fan stops. But still spins full speed, very loud. Have I damaged the motherboard or could it be a dodgy fan? I got sent a Foxconn fan instead of a delta. Ordered a delta to see if it makes a difference. Any advice would be great and thanks for the great content.
I do have the same issue, did you solved it?
@@Ivanyustes1 yes. I used the wrong fan. Delta worked fine.
Me again! had a switch delivered this morning.
no fan spin, new fan didn't work. injected voltage on pin four as suggested. ( was doing it to the power flex at first like a idiot)
fan spinning and charging joycons now. so thanks again.
was this a lasting repair?
cheers.
Awesome buddy, pretty funny about the power flex but it won't hurt anything 😉 yeah I've never had one come back under warranty doing this trick. I think what happens is the mosfet must fail open circuit and injecting voltage kicks it back into life and allows the fet to start functioning again. It's sort of like a stuck gate really, if you give it a bit of a push it frees itself up 😁
Thanks, this video helped me to figure out:
If you have a problem of overheating, and you try to change the fun, but it didn't work. Just try to inject +5v and 0.3A on last pin of the motherboard (in the direction of the type c connector) and the ground - on any shield.
THANKS AGAIN!
What screwdriver sizes do you need
Small Phillips and tri screw bit
what do i need to power the pins for the fan? cuz i’m almost positive i’m having the same problem but i don’t think i have the needs to shoot some volts into the pins
My issue is with the left joy con. New Joy cons won't connect old won't connect. Nothing not even to the hand controller it came with so I don't know what the issue is if it won't connect to the screen part or the TV mode controller
I have the exact same problem, i don't get how you made the fan work
Thanks. I just unplugged my fan now joycons are charging
I live in the us if I send my switch (which is having the same issue) can ya fix it?
Hiya, it can never be guaranteed but I do always do my absolute best. There are several ways to fix the fan spin issue on a switch so there is a good chance it can be fixed
Great chanel my friend
Okey
my joycons are not charging, my console battery is draining very fast and my fan is also not working. is the problem in my fan or my Nintendo switch console battery?
It's hard to say, does your fan work at all when playing games?
@@TheCod3r no
I had the issue with the battery draining fast as well. I believe it has to do with the fan inside the motherboard failing.
@@sonicfangamer101 my battery was fixed on its own i didnt have to do anything
Cool 😎
My fan doesn’t work either. Don’t want to take it apart because I’m worried I’ll break it
Hello mate,
I had this problem of my switch's fan not working and subsequently the joycons not charging.
Was just following along to your video now and I've made it worse. I was trying to lever the heat sink out with my screwdriver (lesson learned) and I heard a electric pop and the machine won't turn on now. I'm assuming I've shorted a fuse.
Do you offer a repair service? If so could you contact me please (assuming you're in the UK)
Cheers!
My switch to overheat too
Not sure why I remembered this circuit was 5v and not 3ish, maybe it bumps up the voltage when the usbc charger is plugged in, I found the datasheet for the motor driver chip in the fan itself (10 pin, 67172 ST) and figured out what the other 2 data pins were doing from that, although it was that long ago I can't remember off the top of my head
So one of the pins is a pwm signal input data line which controls the motor speed and not sure about the other one, id have to check where that 4th mystery pin on the ribbon goes to on the chip, it goes down some vias first so I can't tell from the photo I have of the motor pcb on my phone. If I get time I'll try bell it out ,be nice to get to the bottom of it. looks like the 10 pin ic in the fan is actually a 3 phase motor controller. The pdf I have is titled BH67172NUX
Hello, I get a second hand Nintendo Switch yesterday. I didn't spend money on it, I basically changed it by a old laptop.
The problem is that the switch not charge the joycons, first of all I thought that the problem was the joycons. I tried charge both joycons on my girlfriend's switch and there are okay, both charge correctly. So the problem is my switch. Anyone knows what's causing the problem? I have done replacements on some laptops before, but I don't know what's the part that cause the issue on the switch. I will be very glad if someone said me what part I need to buy for replace it. Thanks!! And sorry for my English, I tried explain it the best way.
PD: I could do a video of the problem if it helps
PD 2: The console has overheating too, docked and handled mode, it shut down after few minutes, I will order new fan, thermal paste, new sliders for the console, and new battery. U think I need something else? Thanks guys.
The problem is something on your fan circuit, but we can not say without doing our own diagnosis. You will need to send it to a repair specialist for repair or diagnosis
The inside of my switch
Hello, my switch in this period emits some kind of vibrations, which do not derive from the joy con but from the inside of the switch, could it be a problem that comes from the fan?
Is your switch bent?
The fix worked but now the touch screen and cartridge reader isn't working. Any suggestions?
