Really a great video! I was glad that you went through the whole process of checking several things. Iโm having a slight overheating problem on my โ05 Outback XT. The fans come on only when the A/C is On. But if the A/C is Off, they donโt turn On once the engine has reached operating temperature.. What could this be??
I have NO check engine light, no overheating, but my AC doesn't work, and the radiator fans don't spin anymore. Any ideas? 2007 legacy non turbo. I can't seem to take my relays out either. It's too difficult
So where's the temp sensor?
Do you leave the 2 green connectors in while you driving? or do you just plug them in to test the fans?
bnj preblame code p0483 est merci
Thanks, this circuit tip is helpful!๐ If the a.c. clutch doesn't activate and the a.c. relay doesn't activate would that create a negative feedback to the computer that prevents the fans from working when the engine is running. The fans definitely work in this mode and the main fan relay is tactile/ feelable but the fan 1 and 2 maybe clicking but I definitely don't feel both clicking and the a.c. relay is not clicking but all fuses visibly are okay. Doesnt an a.c temperature or pressure switch in the a.c. circuit with engine running precede the operating of the a.c. compressor clutch and relay(according to someones' previously seen video indirectly) but how could that then mess with the computer to stop the fans working as regular engine cooling fans under normal engine running priority; in a running flow chart versus this computer to circuit and component diagnostic mode could there be a different priority sequence where the fans are stopped because it is defaulting to a a.c. no function blocking the engine cooling fan function but when I started before erasing codes there was no codes indicated for the ac system.
Example thought: Currently in this diagnostic run the abs is dead as a doornail but there was no abs codes prior to running this diagnosis circuit(seen it by accident in here something I heard in the thoughts to click on this video but that was all I could distinguish and whereby after the fact indirect to do with abs you talk about the Dealer Diagnosis green connector as the other guy calls it) and the abs lamp bulb illuminates on start-up. In one abs presentation the one guy claimed a burnt out stop lamp prohibited the abs system from functioning in that vehicle which intuitively makes no sense but to a pissed-off computer geek it could be a simple fireing back against the world.
Dude You are awesome! I was able to fix my fans after using the green connector trick! thanks so much! I just subscribed and liked the video
What if only the fan on the right works sometimes and the left never does normally while the car is running. But when in test mode both fans run? What does that mean? 2001 outback
How is autel scanner you are using am thinking of getting one
Awesome video brother,It helped me rule a lot of stuff out and save a ton of time.Thanks for helping us nitwits out lol.Keep doing what youโre doing sir,and god bless
If I'm correct, this is the first video in which he changed his moniker from "Dr. O" to "Eric O". This is also the first video where he references us as "viewers", instead of collectively as "YouTube". Cool ๐
My 2005 Saabaru, sub fan works if I jump it but doesn't come on with the a/c or at high temps. Are there any relays/fuse under dash? If so where are they exactly?
Where are you guys located?
I know this is so long ago but please respond. Working on my 2016 subaru legacy… The car is not overhearing yet…but it's pending. Here is the issue, the fan does not come on automatically as it should. I can use the ac to trigger fan and they will come on. temp will go all the way up to 217f fan doesn't come on. I've change thermostat and made sure the jiggle valve is facing the same position as the original. I removed the waterpump and it is not damaged or broken. The radiator is full of coolant and I had the car running with the radiator cap off for one hr to purge any trap air. Also change the engine coolant temperature sensor. Took it on the highway for about 30mins at 80mph in Georgia. It did not over heat but when I can back home the top radiator hose was hot which is normal but the bottom rad hose was just barely warm. What the hell. I'm using a basic obd scanner/reader. I'm able to view live data to see ect temp while I'm driving. At 80mph the car went up to 210f used the ac to turn the fan on and bring it back down. I also switch around the relays with horn etc they all work OK
Thanks for this video! We had this replaced on our 2017 outback 3.6r but only the passenger side radiator fan turns on when we have the AC on and idle. Iโve tried a bunch of different ac settings but none of them make the drivers side fan turn. Is this normal?
Excellent educational content and video Thank you!!!! My dash temperature gauge is pinned in the over H position with the key out or in. Not sure what the to do… thoughts?
If i remove the main fan relay and jump it and only one fan works is the main fan relay bad?
I have one of those Bluetooth OBD2 port things, and I don't have any codes yet, but it says I have a pending P0483. I can hear my fans kick on, so they're working. I might have to check my fuses then right?
When jumping the relay prongs, if the fans did not turn on what would be your next check? My fans work when jumped individually directly to battery. But jumping circuit board did not power them on
Mine problem was with the ac belt can off pulley , looks like plastic pulley melted
Could rhat code be caused by a termostat thats stuck in the closed position?
I just bought an 09 outback. Has all new radiator system belt head gaskets. Was still having issues with heat and smelling coolant. The driver fan wasn't working. Easy fix nowits driving good
How do you charge for that, To many times we work for free on these
Thank you so much for sharing

HI, thanks for the great explanation about the code for the radiator fan. I have a 1999 Subaru outback that has overheating issue. one of the problem is that the fan kicks in when the car is the operating temperature but fan never stop running… I replace the thermostat and bleed the air in the system but still the same… any tips.. i really appreciate it.
could also just plug in the green connectors under the dash and key on. fans should kick on immediately.
The green plugs under the dash. If the relay is bad would the fan still work?
Ok I let my car run for an hour and Fans doesn't turn on. Doesnt over heat. Turn on ac fans still not turning on. But did everything you did and fans does work and relay is good. What else can it Be?
Great video. Thanks for the info.
I diagnosed my fan problem thanks to you. It seems the mechanic didn't plug in the fan… Glad it was an easy fix!
Every fan in Boston has
failed the rationality test
thanks for video saves me alot of time.
Well done mate. Everything you need & easy to follow.
what are the two plugs connections on the top front passenger side of a 2006 outback ?
Low engine coolant level may cause this. I'm working the same issue on a 1999 Legacy.
I see p0692 error on the obd. low level radiator fan is not working. relays works. high level works. do you have an idea to fix this? my car is legacy 2004
some cars have 3 relays
Great video, makes me want to be a mechanic!
Great video and explanation. I have been working on my daughters Outback and this helped narrow down the issue! Nice work and thank you,
Second time watching 7/2/2020
Thanks for posting this. I was getting really frustrated. Same problem…same conclusion.
So if I plug in the green connectors and the fans don't turn on I just need new fans then? They dont turn on with ac turned on either so I'm assuming bad fans right?
I did the by pass with the jumper both fans not turning
Thank you very much love watching your videos. Very thorough
I don't know if you check the comments but I did everything you said and the fans came on every time except for when turn the AC on and when I allowed it to get to running temperature in your opinion what could be the problem
Great description on how to troubleshoot the electrical portion of this problem. I was wondering though why you didnโt explore the thermostat as a possible cause of the error code. A failed thermostat is the most common cause of that particular code on Subaruโs.
Nothing worked for me I have a 97 though I did the relay test they worked. But when I turn my ac is on no fans
What if my fans never kick on even after the green connector test proves that my fans are being controlled by the computer?
I've tried all the other obvious tests as well like the checking the fuses and starting the car and running the AC and letting it get up to temp with no fan action…
