Replacing blower fan resistor on Volvo XC70 P3.
Вставка
- Опубліковано 31 сер 2022
- 2015 XC70 D4 with 180000km / 112000 miles. The blower fan stopped working but was replaced recently. The issue is with a defective blower fan resistor. Replacing it solves the issue.
MAHLE F7253003
To test the blower: short the two thick wires: Black and Black/White.

Thank you very much for the video! I've just replaced it on my 13' XC70 (the fan was blowing with max speed even with the engine off) and i can share some tips that worked in my experience:
1) you can use regular pliers to turn the resistor counter-clockwise, a wrench is hard to get in there and slips right off most of the time
2) at first it seems like you don't need to cut through the carpet material, but once you get the resistor loose you will see it is pretty much impossible to get it out of there without removing the soft material
3) the "carpet material" has 2 layers : harder carpet-like on the top and foam underneath. important - foam seems to be cut all the way to metal all around, but the superficial carpet-like is cut 90% around and only needs to be cut superficially in 3 places (i would say each is 5-8mm)! You will feel the places if you put your finger all the way through the factory-made cut to the metal and run it around. Two of these are easy to cut, one is a bit more tricky. Once you cut it (essentially connect the cuts made from factory), you don't need to remove the whole piece, but lift it upwards from the inside - it will be enough to remove the old blower and install a new one
4) remove the connector from resistor before trying to twist it counter-clockwise as it will get in the way and make it impossible to get a good grip on it. when putting it back in, i found it easier to put the new one back in first, then plug the connector - it was very easy. it would be hard for me to connect it first then try to put the blower resistor in place as like i mentioned, the connector makes it hard to get a good grip on the resistor and turn it.
Final tip: don't loose your spirit, this is a damn hard and uncomfortable job to do :)
Thx so much for the tips. It’s valuable information for all of us doing this job.
Thank you Evgeny and Volvo Sweden once again for a great video that showed me I could repair my car by myself.
It was really tricky to both cut through the fabric since you need a really sharp knife and to reach the resistors and get enough moment to turn it. I recommend eye protection if the knife slips.
Did this during -12 degrees Celsius too so it was a pain. Battery had died because of the blower fan not turning off. Jump starter refused to start car because of electrical problem with the resistor. After changing it, there was no problem in starting the car.
Insanely horrible job, but after 1 hour it's done and it's working !!!! Repair for 35 EUR. Thank you very much for the video.
Interesting video to watch, I’m impressed with how immaculate your friend’s car is. The headlights look like they are made of crystal! It reminds me that I need to clean my own P3 headlights as they are starting to cloud up a little.
Once again you gentleman come through!! Knowledge is key and thank you so much for sharing these tips.
thankyou Yefgeny ...we appreciate your efforts in educating the community!
Thanks I replaced the resistor yesterday with help of this video, but it was harder than I could imagine 😅 the most tricky party was to put the new resistor back. I put som silicone spray on the threads so I could turn it in place more easy.
Thank you for your Volvo videos my friend they’re priceless to me please continue with your work also thank your buddy for showing us more Volvo stuff as well also I have a
S60 2011 And just added a pedal commander it doesn’t give any extra horsepower it just changes the parameter of the pedal it actually is pretty fun I thoroughly enjoy it you should try it
Yevgeny must be a contorsionist in his spare time ! Thanks for the info, same location and procedure on my 2016 V60.
As allways, beautifully presented with details. I appreciate your work, thanks alot for all these helpful videos.
I did this to my V70 last winter. Not a difficult job but really annoing one. Same with the blower fan, had to replace it too at the same time.
Excellent video. Blower resistor it is a very common problem in Volvo. I had the same problem, fortunately the car was on gurantee. Once I reported the problem to Volvo they told me straight away that's resitor problem.
Then after that you decided to watch this video
Great little piece of advice there on jumping the resistor out to check fan is good. I'm hoping the fan comes on full when I try this! Thank you so much...
you guise are amazing, these explanations can save us allot of money , i never seen a video that professional as yours. we thank you for that , keep on the good work......;
Thx so much. We try our best
Thank you for a great video and demonstration
Hoy se lo he tenido que cambiar al S80 de mi hermano, vaya pelada de manos, que casi no hay sitio para meterlas, pero al final conseguido
As allways a good video!👍
Good work boys!
I aways give you a like cause you explaine so very good !!!
All I can say is I hope mine never goes bad. That is a mission.
That’s your mission?
Impressed by this video - but I just can't get the damn thing out. After removing pedal and insultation I can see it but can barely get a finger on it. Tried the wrench but can't get it in there. What a PITA.
Doing it right now and agree. My hands are lacerated and bleeding. Cannot get a hold of the damn thing
Well I managed to complete the job but blower still ain't working. Guess I'll be swapping out the motor now..ffs
If you had that much of a problem replacing the resistor, super easy, I’d love to hear about your experience replacing the blower motor.
Jasonlee just being negative Ass hell. Get out off the page bozo
Nice techno bro, thanks
You are the man, thank you!!!
There is priceless information here and great tips. A great example of how videos like these should be executed. Thank you again.
Thx you too!
I have heard that if you're replacing the fan blower motor, replace the resister. You going to end up replacing both eventually
Great video
Hey bro I had to do this job in my 850, it was deffinately easier that ur job!😉
Do you have a video or the information about updating the navigation data?
im looking to buy a xc70 in near future which model year are the best do you think i want a diesel one.
I had this fault on my 2013 xc70 but the MOSFET failed closed, so the fan ran flat out until the battery died. At least it was an easy fix.
Its kinda interesting that this is the last facelift V/XC70 and it has the old style side mirrors. I saw facelifted V70s with the new model which is thin LED strip, not the big regular bulb one. Weird.
That's an easy upgrade you can do.
Is ot the same with Volvo v60?
Thanks!
I currently need to do something to fix the fan and it stopped blowing sort of out of the blue. The entire panel is working in terms of functionality. I am also able to get the seat heater and all that so it’s not that component. I did, however purchased the relay for the fuse box, but I cannot get the bolt off of the fuse box in order to get to the relay below in the compartment in the engine area, which is really frustrating so I may just opt for fixing the resistor is there anyway to diagnose it without actually pulling on the yellow and black wires as you suggested would you suggest doing that before I purchase a resistor or just get one anyway
Oh your going to fix the resistor are you?
Lmao, well it’s been 3 months since you posted that and I bet you didn’t fix anything yourself. No offense but if you can’t figure out how to change a relay, just find a professional to work on your car
So I have a weird issue with my blower motor, when I accelerate and decelerate the blower motor fan seems to speed up and down in unison with the RPM when in auto mode or constant speed. Otherwise it works normally.
Anyone else with the same problem?
Do you guys think it's the resistor?
For those of you doing this on a right-hand drive car, you don’t need to cut away the fabric under the carpet and the job is a lot easier
Great video. My 2011 xc60 heater has just started blowing full speed all the time (even with the key's out of the car) do you think the resistor is the problem?
I just got the same fault on my 2015 XC70. I have the same question
Yes. But not 💯 %
Hi, I am just doing the job since my fan stopped working.
Concerning the fan check:
Is it really bridging black(without white) and yellow/red?
There seems to be no currency at all.
Or does this refer to a broken fuse or the actual worst case: blower fan?
Between yellow/red and black/white, I can measure 12+ Volts.... but I do not dare to short cut.
Any ideas?
THXALOT
Finally got the fan working again, by simple moving it by hand.
The fuse box for start/stop engines is right below the windscreen; you have to disassemble the wipers....
From there, you have access to the fan through the intake window.
I suppose that something fell into the fan and blocked it. Anyhow, no expensive repair or alternatively several hours as human snake below the dashboard.
I would recommend to do this check in case of fan issues, it is only half as painful as working on the resistor or the even the blower motor itself.
Cheers!
My fan just died. The monitor shows it working, but no blowing. Could easily be obstructed. Will check this first, thank you very much 💁♂️
Thanks volvosweden for making this video, it's been very helpful.
As regards testing the fan, on my 2008 UK RHD V70, I had to bridge the black and the black/white. Bridging black and yellow/red did nothing. I looked at the wiring diagram and bl to bl/wh makes more sense. Managed to blow the Jcase 40A fuse when doing the test for the first time - touched the wrong wire possibly?! But after replacing the fuse and then doing the test again more carefully, my fan runs at full speed, result!
Luckily it's a lot easier in the RHD cars to access the blower fan resistor. Just remove the glovebox and it's easy to get at and on my car at least I haven't had to cut any of the carpet or sound proofing :)
I tried to replace mine and remove it with an adjustable wrench and it did not want to move. It is very small space. Is there another tool I could use?
Also how can I short the wires together to test fan, Do I have to remove the wires from the plug?
Note sure what other tool will help you. Don’t remove the wires from the plug. Just take a piece of wire and short the corresponding contacts in the connector
How hard is it to replace the blower fan? My squeaks a little at lower speeds. I can live with that if it means many hours to replace it.
You need a special tool. 3 hours. ua-cam.com/video/z-9SKu49LBE/v-deo.html
When doing this on 2016 xc60- remove with wire connector on. Replace with wire connector off.
It looks like nuclear control rod 😅
🤣
Can you do a video about how to replace the cup holder cover?
some info is here. ua-cam.com/video/7ewyoi4CBvE/v-deo.html
Seriously you need a video for that?
Wrong wires to test resistor. Jump 1 and 3 on the resistor plug. NOT 3 and 4. I jumped 3 and 4 as instructed here in this video and ended up replacing a blower that was fine for no reason, 5 hour job. 2008 xc70, 3.2.
There isn’t a way that your blower motor got damaged from the wiring tests that your describing even if your correct about this video describing the test wrong.
The blower motor is a 2 wire DC motor.
Also, if your so sure that your blower motor was perfectly fine, why would you be messing with the resistor and stuff. Obviously you had some sort of issue.
Sorry to hear that you couldn’t figure out how to test it.
The blower motor works by getting power on one wire and ground on the other and it spins. If you hooked it up backwards it would spin the opposite way.
The resistor is there for it to have different speeds only.
That’s why I wanted to explain to you that there is absolutely no possible way to damage it from the wiring tests that you incorrectly assumed damaged your blower motor.
3 to 4 will only connect Ye-Rd to blk, which will not do anything. you need to connect BK-WH to BK, this would close the circuit to make the motor operate, but it is pretty high amperage and it if you use too small of a wire, it will melt pretty fast. Not really sure if the motor should get full voltage. I did test, and it blasted pretty hard, it also sounded like it should not be running that fast.
Just wondering, could you test test the motor by just plug the connector to the new resistor before install it in its place?
7:00 Please edit this and point out that to test the fan, you should short Black with Black-White. I just ripped out my entire front interior to get the fan out, which when tested on the bench worked perfectly fine. 😂
Thanks for the input. Fixed. Sorry for the inconvenience!!!
Was the resistor then?
I'm about to do this job in my 2008 xc70; I'm confused, which wires should I jump like we say here in the states
Thanks
@@summerfox9292 Yes, it was the resistor. See above for cables to jump (short).
@@volvosweden In the video you still say to short black with yellow-red which is wrong. It should be black with black-white.
@@bomellberg thanks so much
I have a 2016 XC 60 and the fan is stuck on even when I shut off the vehicle. Would this be a resistor as well?
Definitely not. You have an electrical short somewhere
@@JasonLee-lv7tm it was the resistor I changed it three months ago. Turns out it was the section that deals with auto climate. But it’s still inside the resistor.
I have same problem... The fan runs on full speed even when the car is turned off. I had to disconnect the battery. I maby have to try to change that resistor too...?
It was the resistor! I was on my third one and I realized the ones from eBay were crap! Now that I got one from the auto store, I solved my problem
He def disconnected the positive
Thanks the other video i watched the idiot says its simple you just grab it pull it out put it back in durp
What does “durp “ mean ?
@@JasonLee-lv7tm its the language of your people im not sure exactly
