Ford Fiesta fan problem...faulty relay.

Apparently this is a common fault on Ford Fiestas, the fan carries on running even when the engine is cold. But there is so little information about how to fix the problem. I spent ages researching the problem and traced it to one of the relays. Hope it helps you.

This is great! I am having the same problem with my 2006 1.6 tdci fiesta. It's too dark to try to open the relay box now but will definitely try tomorrow. Yep, tried it and that was the fix. Thanks for the great upload. In my case the relay was some g.cartier crap, replaced it with the ford part.

[@jaredakten4939]

Glad you managed to fix it...I love those mark 6 fiesta...they were built so well

[@aleczandermehl3995]

Thank you So Much, Helped me with my 2007 Ford Fiesta, Except my fan wasnt turning on. Used the exact same method and it works!

What's the problem man.i am facing same issue in my figo 1.4tdci. radiator fan is not running even when i turn ac ON.

@@manjinderwahla8250 just remove the relay and blow the air in female connector of relay just use sand paper and wipe the relay male pin until it turns to original metal color then remove fan wire from radiator use rust lick spray remove the dust now plug it it will works

Thanks for this, now i know what the problem is. I tapped the top of the grey relay with a spanner and it fixed it 😂. So at least i know which part i need to order now 🙂

Great video fixed my issue

I have a 2008 ford fusion 1.6tdci with the same issue. Relay box located in the same position. Part no for the relay is; F80B-14B192-AA. Easy fix.

Hi The coolant sender under the coilpack could be a push in or a screw in item. Most companies keep the push in.

Hi, I have a Ford Fiesta mk7 2010, the engine fan comes on when I’m driving and stays on for 15/20 after switching the engine off. Do you know what this could be please?

[@romanbcf]

bro i love you so much, you save my life and my wallet lol

[@goog173]

Had the same problem. Took it to fords and they provided an up rated relay. I then opened the old one and found contacts stuck together. Cleaned them and is now the spare. The cover simply pops open with a small screwdriver. YEs there is a black and grey relay. ITs the grey one for the high speed fan.

[@jaredakten4939]

Yes you are right Ford did modify the relays in the end I guess they got fed up with the complaints.

[@birdy3634]

Hi my car does shows warm when its cold, it doesn't overheat but the fan also does not come on. I changed the radiator flange with temp sensor as I had a waterless. The fan did not come on before that either. Now I testet that the fan comes on when I pull the temp sensor connection off. But when by running engine I put it on the fan stays on and Fault management light comes on. When I switch it off fan stays off . Can you help me ? could it be the Cable or the relay? And how doI change the cable ?

[@harwoods11]

There is also a coolant sender under the coil pack and a two speed fan resistor at the bottom of the radiator cowling

Thanks for sharing....hopefully will help someone with same problem

[@lindabright7214]

Hi, thanks for the video. I have a ford figo, the fans starts spinning immediately when i turn the ignition and only stops when I turn the ignition off. Could you maybe help with advice ? Thanks

[@jaredakten4939]

Hi Linda...if your car is the same as the fiesta then it will more than likely be one of 2 things...your coolant sensor could be buggered or you slow speed fan relay could be stuck in the on position... both are cheap to fix.....change the sensor first to see if it helps.

[@MrElvis6565]

Does anyone know what the relay unit product code is for a Fiesta 2017 - I can only find the black one made by Bosch called 0 986 AH0 614? Moreover, does anyone know where I can get one while living in Italy.

[@abracadabra974]

Merci

Note that this is the fast speed relay...there is a slow speed relay for the fan behind the glove compartment. Please like and subscribe

I have the same problem if I would change the fan relay could make better and to stop my cooling fan to work continually even the engine are off or engine are on ? Many thanks 😎

[@jaredakten4939]

Yes as you can see my fan was constantly running with engine off. I used to disconnect the battery but better to change relay.

[@craigreaper7295]

Hi - where did you get the relay, and what part number is it? I can’t find one anywhere!

[@jaredakten4939]

It's actually a common one used in a lot of Ford's I will get the part number for you...but have a look at your old one part number will be on top.

[@jaredakten4939]

Part number is f80b-14b192-aa

Salve, l'altro relè accanto invece che funzione ha?

[@jeffreymoteme]

Hi my tempreture goes all the way up to 92 without the fan kicking in please advice me what i can do

[@jaredakten4939]

Firstly check your fan motor then the temp sensor then the fan relay, if they are all functional then I am afraid it's your wiring

[@Tumelofa]

Hi My car ford figo was overheating recently and i bought new Themostat and temperature switch but when it gets hot my fan doesn't turn could that be a fault fan relay aswell?

[@jaredakten4939]

Check the fan motor first then the relays

[@chrisjannienaber2932]

Hi I have a Ford figo my fan is running loud, If I remove the relay the fan is running normal speed, I did buy a new relay and the fan is still running loud What could be the problem

[@Ronniemarges41]

have the same car as you. i just replaced fan motor twice and now its not working again. the mechanic here connect the power of the fan to the compressor because they could not find the problem which is i think is just a relay....

[@fookayou8607]

Hi any idea why in cabin heater would give an issue ? It won’t blow hot air only cold 🥶

[@jaredakten4939]

Yes..sounds like your thermostat is stuck...so hot water is not circulating to the heat exchanger in your cabin..hope it helps

[@fookayou8607]

Jared Akten no I replaced the thermostat still no difference

[@jaredakten4939]

@@fookayou8607 ok next thing to check is the heat exchanger to make sure it is not blocked. Also check the rods/cables from the selector switch to the flaps these might have come off.

Hi my Fiesta 2009 1.6 Tdci is doing same problem. Fan is very speedily on while engine off. I took off that gray relay one day and try to jump start as the fan killed all the battery and finally I damage the ECU (electronic control unit) and cost me £500 to make the car live. Now having same problem the fan is on and on. I am scared to take off the grey relay and put new one. Need ur advice please. Thanks

[@jaredakten4939]

Just replace the grey relay with a new one..and just to be safe don't start or drive your car until you have fitted the new relay. Did you accidently reverse the polarity when you jump started the car?

[@TheSajuahmed]

Thanks for ur reply. I am not sure if I mixed up the polarity but I try to jump start without that relay.

[@jaredakten4939]

@@TheSajuahmed the damage to ecu is not because relay was removed. It's from the method of jump starting, the safest way to jump start a car is to indirectly connect the battery negative via the engine block.

[@TheSajuahmed]

Jared Akten you were 100% right. I changed the relay and fan running all right. If I would know at beginning then I wouldn’t have to pay £500. Thanks

If radiator fan do not switch on do I change the sensor or relay switch

[@jaredakten4939]

Check fan motor first then sensor then relays...remember there are 2 fan relays on this model so both need to be faulty for the fan to not work at all. So probably the motor is gone or the sensor..

I followed all of this but when I opened up the black box next to the battery there is just a single black relay in there - no grey one like the video.
