Unbelievable... Fan Module Causing Ford Focus To Run Rough?  

O'Reilly's sells this exact part for $287 (I just bought it yesterday). They are the ONLY retailer I could find for this part. The part number is FCM125! I hope this helps anyone looking for it.

excellent video and information sharing, really helped me to resolve my issue as i visited many mechanic and they dont even understand why i was missing throttle pick and also intermittent fan off. appreciate your support

gotta be honest, I thought your theory was a little far fetched until you put it back in to verify. THAT was a good video, not a typical RU-vid "here's how I fixed it" video.

Appreciate you taking the time to troubleshoot and then sharing your findings with us on your channel. This info should be taken as a warning on not to "short cut" your way to making repairs especially on critical items involving the engine, power train, or vehicle's safety appliances. "Exact OEM replacement" or don't do it at all.

Ive been runnin in to that overheating problem. I replaced the Fan, water pump, ECT Sensor, and thermostat. Im surprised. Ive never seen this kind of craziness with a car either. I also have been working on cars alot.

Im doing just that Sir. Ive never had to Pray 🙏 this much for an car 😂 i went ahead and ordered the OEM part. I wish you well Sir with many blessings from the Car Gods. Im hoping that what i ordered comes and takes care of this issue. Have a great day sir

I learned a long time ago that it's never worth it to get cheaper car parts. 09 for focus owner here facing the same issues. Thank you for this video.

I just grounded the black wire on the fan to frame. Easy fix

Awesome Video, really helped me out ! Just fixed my 2013 focus with your great video. Put in a used oem from a junkyard and it's working. Thank you

Yes it does make your vehicle drive rough because I just replaced mine and I can't believe the difference.

That was the best Amazon review on a part I’ve ever seen lol

I’m also having this issue and I just did research figuring out what the problem was and stumbled across this video. I work at a ford wholesale parts warehouse and even asking the sales guys they said the only way to get this module that fits my 12 focus is buying the entire fan assembly. I appreciate your video however I did see mixed reviews and for $30 on Amazon I’ll atleast give it a try before spending 350 on the entire fan. Will be sure to update and reference this video as well as your installation video!

You are one smart guy. Keep making great videos. New subscriber..

Just watched your video after my module died on my 2012 focus, big thanks for the heads up and saving me a potential headache.

I have a Ford Galaxy with no workibg AC. After diagnostics it turned out the fan control module is bad. Since it is summer after driving for a while in town traffic the car seemed tot overheat and some fumes came out under the bonnet, also the coolant level dropped. Now it makes sense since the fan does not work. It did not occur to me that these issues are related. Thanks for the explanation now I know for sure one fix will solve two issues

I stop going aftermarket when it comes to sensors and modules I learned that the hard way when I was dealing with a faulty crank sensor got one from eBay had me going back and forth thinking I had timing belt issues. Went to the junk yard picked up a used but original sensor and all the timing problems went away.

Thank you very much.

Lol . I tried to put a grounding from the module . It doesn't work at all .

Fantastic information. Thank you.

I tore mine apart I have a 2012 ford focus se sedan, the "battery" on the inside of it or mabye its a resistor is super rusty so I'm replacing it. I'll let yall know if it works and I can send you a link to it! If it breaks on me i'll edit my comment too.

Those Amazon modules are JUNK. Just had one quit in less than a week.

Thanks Man for the info! I am having the same issue first with the fan and now I'm running bad with no power and bad mpg just like you said, I just bought that 20 buck piece arrives tomorrow. Question, Is necessary buy the purge valve in this scenario?

I just installed probably the exact same module in my wife's car if we have issues ill try grounding it first

Thanks. My Amazon part comes in today. I will keep this in mind and let you know how it goes. Fingers crossed

Thank you soo much, I am getting code p048 but my fan was coming on now and then ,my car runs crap, I cleaned the throttle body,all sensor cleaned,replaced fuses and relay,spark plugs,evp ,water pump,bleeding the system,still over heats and rough idles.... I think this is my last option buying this

Would your transmission overheat when you were idle on the red light or on the stop because my transmission would overheat cause from a red light on the road Or if I was driving slow on the freeway my car would overheat we have the same car

Just canceled my order 🤘🏽 I appreciate it! Oem is the way!

Can I ask you a question maybe you can help with? My daughter has a 2015 Focus that keeps overheating. She drives it about 30 minutes and gets the dash warning that the engine is overheated and she should pull over. When she does and turns off the car, it won't start again for about 45 minutes. Then it starts and runs fine. We put a new aftermarket fan and control module on it from partsgeek. Same problem. Today I was checking the fuses in the engine compartment and when I pulled fuse f32, the fan started running??? The car was off... The keys weren't even in the ignition? I think fuse f32 is for the cam/crank sensors? Any idea why pulling that fuse would cause the fan to come on?

Im having issues with my fan running on high intermittently even after short runs when my car is off and when i open or close driver door. Do you think this could be a faulty module? Replaced temp sensor but no difference and car is not overheating and runs great.

Could find OEM anymore. Ordered on off eBay that SAYS OEM, but don't think it is. Like 25 bucks. Hope it works

i have same module but OEM Bosch, the case measured no continuity between supply ground and case. this problem sounds like inappropriate PCB design resulting in excessive EMI emission. i've seen these Chinese replacement module were totally different compared to original ones. i dont even recall the existance of inductor which exists on the OEM module. that alone will reduce EMI immunity significantly. Gates made various replacement module but they're quite expensive. they might be a better replacement if you cant get OEM ones

change the fan module, it is a bosh brand, now the problem it gives me is that the antifreeze tank boils!

Great troubleshooting! Yea these cars with sensors Im working on my GF mom's ford van WTF? im glad all my rides are pre computer I swear these china parts blow. I just dumped a PSD F350 cause of all the damn sensors. loving my IDI F250. Thanks for posting this.

I can hear the frustration in your voice in this.😂

My fan will not come on, changed that part and still nothing.

Only buy parts that are either OEM or a brand name, at least.

I have found too that OEM is usually the way to go. I hope you left them a comment!

Thank you ❤

Great diagnosis and thanks for the video. Ford should be sued for this design. That this issue could even exist is insanity.

Just bought a used OEM one that does the same thing bucking not shifting revving then shutting down while driving I really don't want to buy a new one.

Try as I might I can't find a Bosch fcm. I came here after installing an ebay "made in America" fcm and am having the same issues you've described. I can only find Bosch fcm off of wrecked cars. The junkyards were no help. They could tell me what vehicles were in stock, wanted $109 for a fcm and no returns. Any advice on where I can find a part w/o paying Ford for a new fan with module for $320. I just put a new Dorman fan with module on it. The module that came with the fan didn't even fit on the car, but the fan did so I used the old fcm. Now the fan only intermittently runs. Same issues, no cold air sitting at a light, windows won't defrost in the rain bc the ac doesn't always work. It occasionally overheats sitting in traffic. Let me add, while I've been unhappy with this focus, since I bought it due to the transmission issues, it does have nearly 300,000 miles on it. So I've got my money out of it.

Question. My daughter has a 2012 ford focus and after it’s driven a while the fan is very very loud. It’ll be loud even after car is off for 3-4 mins but now her battery keeps dying, but it will start after being jumped. My husband thinks it’s the relay switch? Please anyone? The fan is sooo loud. Is it something else? Alternator?

Where is the link to the right part!! Disregard I see where you said you got it on EBay. Ordering now.

How did you do the tests on the module and fan? My fan isn’t turning on at all and I’m not sure if it’s this module or the fan motor itself

I don’t know anything about cars but I just bought a used one off eBay for $100 can someone tell me if I overpaid or is it correct price

beautiful birdsong in the background 😊 🐦

Wow.. cool video great diagnosis.

Good day sir. Try as I might, I can't locate a BOSH unit on ebay for my 2012 Ford Focus. Do you happen to remember the name of the shop?

Very helpful one!

Will that make my fans not come on in a timely manner and make compressor not come on at times

Thanks man for the info

What year was this car? I really need help.

so i can just order the junk one and put a ground wire on it right? save a few bucks and still have the car run good

Bonjour, Je souhaite remplacer cette pièce sur ma focus 2012. (BOSCH 1 137 328 567) En effet mon ventilateur moteur se déclenche des que j'allume la voiture ou parfois en roulant. Le moteur ne surchauffe pas mais le ventilateur tourne en permanence même à froid. Pensez vous que cela va régler le problème. Merci

Would your transmission overheat when you were idle on the red light or on the stop because my transmission would overheat cause from a red light on the road Or if I was driving slow on the freeway my car would overheat we have the same car
