- 2014 Ford Focus ST radiator fan not kicking on solution.
EDIT: If that fuse blows multiple times after short drives, your O2 Sensors are bad. Replaced both of mine and ever since then the fan has been working properly. - เกม

If you plug the new fuse in and it immediately blows, one or both of your 02 sensors are bad and need to be replaced. That's very important to pay attention to. Thanks for watching!
Ford mechanic here. I looked up the fuse information on the Ford technician website and F32 in that fusebox is the fuse for the cooling fan relay, not the o2 sensors. Which makes perfect sense to me. That's why the fan worked when they hooked it directly to power. They basically just bypassed the fuse and relay all together.
If you had an issue with anything to do with the o2 sensors, you would most likely have a check engine light on as well. Hope this helps the issue make a little more sense to anyone reading 😁
So question, why is it that relay only blew when both of my o2 sensors went out? Once I got those replaced that fuse never went out after that and I never understood fully what correlation that fuse had with my o2's and the fan
@@xXTruBum14XxTv they may not have actually been bad. Would the fuse blow immediately when replaced before you replaced the O2s?
I didn't look over the wiring diagrams, but if that's the case, there may be a shared ground or power source that I am unaware of. I could definitely see the fuse blowing if the HO2S heater circuit was shorted in the sensor and it shared a common wire with the fan circuit
@danielcevello6148 yea they were charred lmao. The first time I replaced the fuse, it held for maybe 30 then blew
👌
Update. Thanks to this video!
My radiator engine fan is now working and the ac too! Magic! Thanks a lot for sharing this! ❤
Thanks for the info, I ordered the fan module.
Then I found your video. It worked like a charm, thanks.
Bro! I've been thinking of putting a remote switch for the fan because of this problem. Im heading to parts store today to try this fix. This is god sent
I was thinking about running a switch for the fan but decided to wait until I get a bigger fan haha. But yea lots of people have thanked me cause I've kept them from dropping hundreds of dollars on stuff they don't need when in reality their o2 sensors and that fuse are the only things that need to be replaced. This is a tricky problem mainly because everything you'd change dealing with the fan won't cause the fan to turn back on lol
Having same problem with my 2005 hatchback. Hope this solves the fan not working 😊 thanks for sharing.
I have a 2021 Focus base but I'm having this problem now. Hopefully this will be the problem. Thank You!
Dealing with this one right now myself, so hopefully this is it, will check that first, thanks
Thanks for this. My fan has been misbehaving will check this out.
No problem!
Bro I saved me so much money, thank you. I replaced that module about a year ago and it worked, now again my fans aren’t working, spent another $25 for another module and it wouldn’t work. Was about to spend $300 on some fans when I found your video and bro wtf.. a fuse!??? Lol
Exactly! I had my car at the dealership (non ford) and they kept telling me it was overheating but didn't know why. Had them give me the car back and turns out the fuse that had blown went out because my upstream O2 sensor had gone out, replaced the fuse and the sensor and bam, fan was back working like normal haha. If you drop the fuse in and after a couple of drives it goes out again, one of your O2 sensors needs to be replaced
Guys, a blown fuse is only a SYMPTOM of a problem, not THE problem itself. Replacing the fuse will not solve the problem, it only creates a temporary fix until the new fuse blows again. You have to diagnose the root of the problem not just replace a fuse.
Sometimes fuses goes out 🤦🏼♂️
@@fairfax_fran5109go out where to ? 🤔
Thanks! I had similar problem
Rest in heaven my baby❤❤💜💜I miss you more than you know
There’s a large fuse in a thin case that has 8 fuses in it with a single large wire between the battery and air box. My relay was good, F32 good but fan still not working. Ran lead from battery to fan, it works and to control module, it works. Now all I have left is the one big fuse between the batt and air box. I just can’t figure out how to test it. This is my last hood before dumping huge $$$ to take it to a shop or dealer where labor is now 145-170/hr vs in June 2020 it was 85/hr.
Fuse F32 is the heater control module fuse, not the O2 sensor fuse. The mechanics in the shop must have been pretty terrible if they didnt check the fuse first. This is literally the first thing you do in electrical fault finding. The fact that they didn't check if there was any power to the fan control module before condeming it is pretty embarrassing.
so i was driving and my ST had over heated and turned off had 2 miss fires before shed lost all power. called the tow truck and 45 mins later she started right up. my battery is toast and my AP is giving me a code for my fan control unit . so im about to swap both and go look at those fuses. im FBO running e30 and have 115k miles this would be the first time shes took a dump on me aha. thanks for the video
yeah my is the same i be driving and i’ll see my temp on AP and it will just start too climb and then get misfire and then bad octane will drop but will check out if it’s that dumb fuse smh
I have a 2014 SE with the same issue. Any idea if that’ll translate directly for my model? Would much rather replace a fuse than a module or the whole fan
Definitely check the fuse, im not sure if the fuses are in the same spot across all years/trim levels, but you'll be looking for the fuse that powers your o2 sensors. If that fuse is blown, then one or both of your o2 sensors went out and will need to be replaced. Fixing that, assuming that the fuse went out, will fix the fan since they run along the same circuit (thanks ford!🖕🏽)
Check your owners manual or online for it. Different engine means fuses control different components with most cars with varying models like the focus. We have a EV, a 1.6 1.8 2.0 and 2.3 and diesel depending on your country.
This might be a dumb question, but could It be the same issue with a 2015 Ford Focus titanium
I have a fan that works for about the first 10 minutes, after that it won’t turn on again unless the car sits for a while. Did your fan do that as well or did it just not come on?
Mine does the same, in the heat I can run Max AC for about 10 to 15 minutes and then the cold just drops off
You could actually hear the globs of adderall make it into his throat on that snort 😂
My fan will turn on, on my ST, but it seems like it’s not reaching the high speed it’s suppose to. I change the thermostat, put new coolant and change the valve cover gasket and with the AC off my car will drive fine, but if I get on the highway, the needle will go a little above the halfway and will go back down when I slow down. If I have the AC on, the temperature will go up. What do you think?
hello, i have the same problem in my fiesta ST2015, are you able to fix the overheating issue with the a/c turn on?
Normally, a car will overheat if stuck in traffic but will cool down once on the highway due to better airflow. But your case if the reverse. When you have more air flow you are getting hotter! This usually means a lack of coolant flow. As the engine RPM increases you aren't getting an increase in water flow, but when you slow down the engine cools down again. Check your water pump, thermostat, and coolant passages for blockage.
You think this might be the same issue for a 2015 ford focus saden SE?
Identical cooling system. So maybe. The fan control modules (sets on the upper driver side radiator fan) is also a common failure point.
I think something’s is stuck in your fan. I dropped a roll of tape in my fan and forgot about it and I think it Jamed or did something to where it started making a weird noice and then the fan fuse blew
I also have a F60 fuse (under glovebox), that blows every time I put a new one half way in, with car & ignition 100% off, unlocked:/ :/
does this work on a fiesta sport lol
Great video thanks 👍 , but on my Ford Focus SE. I turn on my car and the air-conditioning, and the fan works fine so that rules out the cooling modulator, right? Checked all the fuses, nothing blown, but still the cooling fan won't turn on when its time to cool off the radiator 🤔 Anybody help😁
I replaced the whole motor with 17,000 mile motor new fan and module but I ended up bypassing the module with a thermostat but I will check that fuse because I rather it work through the module
Super
Hmm, maybe there's a bad ground and some of the current for the fan is running through the O2 sensors? Weird.
The F60 controls overhead dome, drivers side door power pack , cig lighter. Those are all disconnected and that F60 keeps popping.
If you have an engine light currently on, I would assume your O2 sensors need to be replaced. That was why mine kept blowing when putting a new one in.
I have a fiesta 2014 titanium. Same issues it’s intermittently overheating to 3/4 and going back down. Replaced the thermostat, coolant temp sensor, coolant overflow tank & the radiator fuse & relay for that fuse😑. Not loosing coolant not getting white smoke no milky residue on the dipstick or the engine cap. If this fuse is the issue I’m going to lose my mind. 4 weeks and countless nights of reading forums with no solution in sight. Going to give this go and will report back because I also have a code for 02 sensor
I almost blew my shit when I replaced my O2 Sensors and the fuse and my problem was fixed. So much money down the drain just for the fix to be so much less costly and time consuming
@@xXTruBum14XxTv do ya know if my case could be a bad heater control valve ?
@@spacecadet517 Nah, that alone is mainly for AC temp control. Now, however, if you don't have a splash guard/ under tray, there is also a possibility the fan assembly could be shorting out from hitting puddles or running the car through car washes. So that's also something to consider if replacing your o2 sensors and fuse don't work
True
so was your car saying transmission overheating or was it something else ?
I was getting a code for both O2 sensors, but these cars have a overheat protection feature that puts the car in limp mode it realizes the overall engine temp is too high, to try and protect the car from warping the block or breaking the head gasket
How much did it cost to change your head gasket?
It was under warranty at the time so I didn't pay anything. But the general price in my area for my car was $1200
I Also had to change my Head Gasket because of this
was your car stalling out while all of this was happening
No stalling, but it would go into limp mode. Felt like it shut off 2 cylinders which gives you no power whatsoever. It does that when engine Temps get too hot (no coolant is being cooled when the car is sitting or going too slow) to protect itself from warping the block.
My car is overheating and they are no leakage, only 200 km k have to check the water, what i can do
Is your fan turning on? If yes, your water pump might not be working. If that stops working, your motor can't be properly cooled
@@xXTruBum14XxTv its coming error DTC#01 E101_00 ,,, yeah fan is working and its expensive for repair water pump
I’ll check the F32 fuse
All ground are in vgc, no frays, rust, tears etc.
I think thats why my engine blew up,it never overheated but now my fan was alway on
I changed the module and it didn't solve it. the problem persists. someone else?
Yes I also changed the fuse, but it keeps burning
F32
Yup that's what I said
@@xXTruBum14XxTv yup that's what you said
@@rapinncapin123 alright then
فيوز شماره ف ٣٢ رو چك كن. اگر فن راديوتور كار نميكنه
You said F32
That's correct lol that fuse blows when the 02 sensors go out. When that fuse is blown it causes the radiator fan to stop working
@@xXTruBum14XxTvI believe after all my homework, when the upstream O2 sensor heater goes out (blows fuse #32) it causes the cooling fan control module to lose ground. With that fuse out of commission, the cooling fan control module still has power, but no ground. Therfore the cooling fan will not kick on. It's definitely a glitch in how the wiring harness was put together on this rig. But if you run a temp ground from your cooling fan control module & run a wire from the power side of the module to the fan wire.. Boom.. You can have a fan until it's fixed. Craziness! 🤘
