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

[@opiumelite8026]

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.

[@opiumelite8026]

Also, it worked!!

[@92sportster26]

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 KZbin "here's how I fixed it" video.

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.

Thanks for watching!!

[@danieleghed7613]

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

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?

[@ProjectDIY2]

I’m not sure what you mean by purge valve… if you bought a cheap aftermarket fan relay then you need to get an original Bosch fan relay.

[@Callie83]

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.

[@ProjectDIY2]

I found this… verify your part #’s before ordering though: www.ebay.com/itm/335198680254

[@Callie83]

​@ProjectDIY2 Sadly it doesn't fit my 12 focus. The part looks the same, but there are no measurements to confirm. I have found a few off of wrecked vehicles, but they all don't take returns and say they are unsure if they actually work.

[@CorettaRalinala-z6g]

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

[@ProjectDIY2]

Could possibly be a blown head gasket. Unfortunately these cars are prone to that.

You’re welcome!

[@tarnishedtime606]

What part did you end up buying that worked?

[@ProjectDIY2]

I bought an OEM Bosch part off of eBay.

[@drew5260]

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

[@ProjectDIY2]

Turn on the AC which should run the fan ask the time, unhook the module from the fan and check for voltage in the terminals on the output side of the module. If you have voltage there then it’s your fan. If you don’t, then unhook the module from the wiring harness and check for voltage in the harness. If you have voltage there then it’s your module. If you don’t then you’ve got a blown fuse or a wiring issue.

[@tarnishedtime606]

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

[@ProjectDIY2]

It should say Bosch on it. That’s the OEM brand.

[@Modernaire]

Thank you for this video! It helped me diagnose the exact reason my 2012 Focus Titanium was overheating off and on recently, AC was intermittent as well and there was a bad smell coming through when it wasn't working, just odd stuff. SO MY SOLUTION was simply to go to the junk yard and hunt down one of these bad boys, the Engine Cooling Fan Controller Relay, OEM Ford 'Made In France'. Easy removal if you take the airbox off first, bought it for under $100 WITH 90-day warranty just in case, and bingo. Works like a CHARM! My overheating problems went away, my AC now works completely like new, powerful, blower, no stale air stench, AC works when idling, etc. etc. Apparently as far as I can tell the fan controller also is part of the AC system along with engine fans, etc.

[@ProjectDIY2]

You're welcome and thank you for watching!

[@donhicks1]

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?

[@ProjectDIY2]

I’m sorry, I’m not sure what would cause that. That is a strange problem.

[@donhicks1]

@@ProjectDIY2 Yeah... It kind of freaked me out when I pulled the fuse and the fan came on 😂 Thanks anyway. I think I'll take it to the garage and see if they can figure it out.

[@CarolinaOats]

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?

I honestly can’t say for sure, but I would guess the fan motor is going bad since it’s loud.

[@JerzyBoy973]

@@ProjectDIY2 just about to order one now. I fished the bad one out of the trash and tried grounding it but no luck. Mine was behaving differently though. It was putting out battery voltage until I added the load of the fan. Then it went to 0 volts out. And the fan works normally when hardwired. So I’m running on a direct fused line with a manual switch until the eBay module arrives. This has been a real pain.

[@n.shiina8798]

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

[@ProjectDIY2]

Could be. When I grounded the case that blocked the EMI.

[@mrcleanisin]

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!

I do have a question however, did you have an issue with your fan kicking on and staying on several minutes after turning the car off as well as opening your doors?

[@ProjectDIY2]

Thanks for watching! I did have the issue with the fan staying on or even coming on randomly but I think that may be a body ground issue. As I understand it, the body ground right above the battery gets crusty and you can remove the bolt and clean it and the area around the bolt hole with sandpaper to fix it. Also, you should be able to find a used OEM Bosch fan relay on eBay. Good luck!
