This guy is really amazing he went through the extreme and step by step to inform everyone that was watching or would be watching exactly how to diagnose if your car has a fan that continues to stay on I must say this guy's really smart he knows his stuff and as far as his accent hey that's where he's from you just have to understand what he's saying take the time to listen if you just take the time to listen you would understand word for word what he's saying I understood every word he said my car has the same problem my fan just run run when I turn the engine off so God bless this guy and his family may you keep on doing good and the more good you do the blessings are going to keep coming on thank you so much for the video...

What a helpful video. Your explanations made a complex system of interconnected parts seem simple, even for an amateur like me. Your logic to eliminate the sensor and computer was both particularly brilliant and made the whole system finally make sense. My car's accessory fan undergoing a similar malfunction suddenly seems solvable. It's not quite as simple to access as the main cooling fan, but I'm feeling ambitious now. Thank you.

My Appraciation: You nailed it bro. Other KZbinrs go for a Quick Click Bait solutions thinking the issue is a cooling switch. You had helped me diagnosed the real issue and learn more about the cooling system electrical network. A multimeter is also helpful to diagnose this issue. Most people think a Radiator Fan Module function is to only control the Speed of the Fan Motor not realizing that the Module is an On/Off Switch that can stuck on an On or Close function like a relay. My Opinion: Some electrical fan are actual controlled by a relay and ECU, while modern generational cars uses a cooling sensor, ECU, Thermostat with a electrical sensor and Fan Module to perform the work. Best cars are the ones which Utilizes the Manual Fan mounted on the engine. This electrical fans are unrealiable and none durable at best. Are caused of majority of engines overheating due to their malfucntioning tendency and overcomplex ssystem that makes no sense. Straight engines should not use electrical fans and cooling sensors. An engine only need a radiator, fan and thermostat. Modern day enginners don't create solutions but problems in their quest to innovate the old trial and tested inventions. The automotive car industry went from cast iron material to aluminium and now they settled to cheap plastic foil cars. It is crazy what shareholders can do. Good luck car owners who are forced to became part-time mechanic because to garbage quality...Nxm

Hi, Recently my Mazda 3 2011 had a similar problem with the fan staying on for about 2~5 min after engine off. Sometimes only a short distance within 10KM was driven, and the fan was still on after the engine was turned off. so don't think that overheating of the engine requires a fan to cool down. In your experience, think it is a fan control module problem, thermostat problem or coolant temperature sensor problem? My car fan control module it look similar like volvo, it made by Bosch as well.

Hi! I have a 2011 Ford Taurus SEL and i’ve been having the same issue where my fan stays on until battery dies, I replaced the Temp Sensor and also the Thermostat. It seemed fine, the fan would turn off and wouldn’t be Stuck On but last night it wouldn’t turn off! Though I only waited about 5-7minutes but PTSD made me disconnect the battery so I wouldn’t need a jump lol My point is that it’s still turning on and off which might mean it’s not the module being shorted, two parts were replaced but last night 5-7min stuck on even after engine was off was frightening, do you think it could be anything else? or perhaps it was just a false scare

Hey boss, I have a 2012 Ford Focus SE that had a problem with the fan staying on for about 10 minutes after shutting the car off. It would kick on when I opened my front doors and kick back off if I didn’t start it. The other day my fan stopped working at all, so do you think the fan motor could’ve just burned out from running so much? I’m getting ready to trade in the car soon anyways, so I just need the fan to at least work and keep the car cool. I should be able to just buy the fan and replace that part hopefully right?

@Unknownuser017 you need to get it diagnosed by a pro mechanic!

[@tubetime39]

Some confusion ( but I will watch again), #1 is the fan controller just a relay ? #2 how does the violet wire control the fan, what does it do other than just brining a signal from the computer ? Is it really a controller? Is there a resistance in the wire or connector that makes it a 'controller wire' ? #3 doesn't the computer need to first receive a signal from a sensor ( like the coolant temp sensor?) before it sends a signal, to the fan controller, right ? This is all new to me but I am having issues with Ram PM Van 3.6L gas and can not afford how have someone fix it. I am seeing people say $1,500 and a lot more for maybe a bad wire, relay, module or the like, that I could possibly fix myself for a few hundred or less. Thanks !!

[@tubetime39]

If i can learn enough that I could help others fix their vehicles also that can not afford to take some place, that would be a huge plus for me ( not for my ego, but doing something we all should be doing, helping others). My added 2 cents.

[@KITS_Auto_and_Truck_Repair]

Wondering Why on this model, the fan module is part of the fan assembly, the ECM receives the input from the ECT then sends a command to the fan module to turn on the fan! but some fans are just controlled by relays! you need to find out how your fan is controlled!!

Good afternoon, I watched your video, my Volvo V70XC 2001 turbo, my fan has a fault. When the car is cold, I turn the ignition ON or start the car, the fan turns on at a low speed. When I turn off the car the fan turns off. But when you turn it on or turn it on, whether hot or cold, the fan turns on and stays that way until you turn off the car. Before watching your video, I bought another fan complete with its module and the same failure. I did the test in your video and disconnected the harness with the cable alone, the color violet and the fan turns off, the two fans that I now have complete with its module turn off. Disconnect the temperature sensor harness and it indicates -40 degrees Celsius, but the fan stays on, does not turn off, What could be the fault? What do I need to validate to be able to solve it.

My 2010 Toyota corolla professional if i turn on the Key and turn it off the fan goes on and if i turn it on then the fan goes off even if the car was parked the whole night. So if I take off one battery terminal and connect it back again then the fan goes off. If I start the car the fan will be of until +-15min then the fan kicks on. I have changed a temperature switch, Fan Relay and Fan switch module but problem not solved.

[@KITS_Auto_and_Truck_Repair]

lufuno brendon munzhelele Since you replaced all those components, it sounds like you problem might be in the wiring or the ECM itself! you should have it diagnosed!

[@thabangmokhele4599]

Can you go back please, disconnect a coolant temperature sensor and test a signal to the fan control module, I want to understand whether the signal wire is giving the module a ground or a supply, I have got a same problem and when my signal wire is disconnected I get 12v on the side of the module.

[@KITS_Auto_and_Truck_Repair]

Thabang Mokhele disconnect the module and see what kind of signal you have there!

Michelle Mull can you check to see if your fan is controlled by a module? it should be on the fan housing!!

Hello on my 2015´s Golf GTD 135kW, fan can´t stop running, only after inserting key and switching into first position, diagnostic show only theese DTC´s : -U112300 -0100300 -U042800 -P068B00

Hey man, I just bought a brand new cooling fan to replace the broken one but I’m worried what I just bought is not working. After installing the new fan, how do you know if the newly installed one is working? I try to idle or drive the engine so the temp guage would go past halfway the mark but it never goes past the half mark of the guage and I never hear the fan turn on. How do you test the fan? I’m asking because I only have 30 days to return it if it’s defective. Thanks

[@KITS_Auto_and_Truck_Repair]

Kirk Lopez you can send power and ground on the big wires on the fan to see if the fan will come on!

[@kirklopez2031]

@@KITS_Auto_and_Truck_Repair I see. But would it need a signal from the sensor first to turn on the fan? How would you fake bypass that and just connect power to turn on fan just to see if it works?

[@KITS_Auto_and_Truck_Repair]

@@kirklopez2031 yes, that's the quickest way to check a fan, if it runs after sending power and ground to it, then your problem is most likely the wiring or the inputs to the ECM or the ECM itself!!

Mine does the same thing but the fan assembly does not have a module on it. It is a 2008 Lincoln MKZ . Wonder where the module is located or if it could be another problem. Thanks.

[@KITS_Auto_and_Truck_Repair]

Chris Baker check in the fuse box under the hood if there is a fan relay in it, and disconnect it to see if the fan will stop,

[@chrisbaker528]

@@KITS_Auto_and_Truck_Repair First thing I did and it of course shut the fans off. I took it to Ford dealership and they put it on the computer. Nothing showed up. They consulted the manual and said it was the cooling fan module. It will cost $1,200.oo plus tax to get it fixed.The cooling fans are $624.00 and labor $600.00. The fans on my car does not have that module on it. Strange to me. I feel it is the fan thermostat control but I am not a technician. So I had to make the appointment.

@@KITS_Auto_and_Truck_Repair Update of 2008 Lincoln MKZ fan module: I did purchase the FOMOCO cooling fan module(two fan unit) from the dealer n Huntington WV who had to call to PA. to find one. Said it was an almost obsolete part(hard to believe). Anyway it cost not the $624.00 previously quoted but $724.00. Guess the Yes Ford dealership had to make money making that phone call for me to order it. I received it this past Friday and I installed it on Saturday. Saved myself $600.00 installation fee. It took me one hour to install it. I guess the dealerships have to feed a lot of people to charge what they do so $600.00 per hour is not bad if you can get it. The fans I saw on line like the one I purchased from the dealer were around $250.00 but did not come with a 2 year warranty. Guess that is why the dealerships can charge around $500.00 more per item than what can be bought on line. Dealerships are a huge money making machine. I am glad I got it fixed for less then the dealership told me it would cost. Thanks for all the information .
