We really liked this video because you were able to diagnose this problem without using ANY kind of diagnostic equipment. You used common sense and was able to not only fix the problem, but tell everyone how to find out which fan goes to what, and you did that without even having a wiring diagram. NEXT: that was so nice to see Rose start the car for you, and SO FUNNY, when you almost forgot the plastic bag. Great video!!!!
I subscribed because of your little helper. The video REALLY helped me on my fab but the genuine interaction with your daughter is priceless - thank you for showing her honor and respect at such a early age - look out men and women this one will know her worth. Bless you and bless your little princess.
@ Non Mechanic 101 My car is a 2016 Hyundai Accent i would like to know if i can turn the ignition swith to on position and turn the compressor on to check if the fan is working?
So the coolant temp sensor is not the sensor that sends info the computer? There is another thing called sender? I have the same issue where the radiator fan is on full speed at start, but when I read the coolant temp with OBD II scanner , its correct and where it should be.
Have a question i have the same car hyundai accent 1999 i have the same problem only diferent is that my fans tunrn on bouth when i turn the ac on they bouth turn on but the radiator fan sopouse to turn alone without the ac on do you no what it is
Dude one is called the Fan Switch Sensor which monitors the temp of the coolant to turn on the rad fan when it reaches a set temp while the other is called the Coolant Temp Sensor which also monitors the coolant and sends the temp reading to the ECU of your car, then the ECU makes calculations so the engine gets the right mix ratio of fuel and air!.
Uh Lincoln Town car kinda the same issue fan turns on when you hit the key but it's intermittent Sometimes it doesn't come on and sometimes it does but the heater never changes always blows mild air
And one more tip. Both fans should always run if you turn on the air conditioner or if the engine is hot. If only one fan is running, then your air conditioner will not blow enough cold air and the engine will not cool down enough.
@@kevinhancock4064 If the evaporator freezes, the fans turn off, and when the evaporator melts all the ice on it, the fans turn on. If the evaporator were to freeze completely, that ice on it would prevent airflow
@@kevinhancock4064 They are turned off if the evaporator freezes, to allow the evaporator to heat up and melt the ice. When the evaporator has melted the ice off itself, the fans turn on to keep the air conditioner blowing cold air.
@vedranhrzic-jd3li interesting ..atm my cars fans dont come on when hot but its suspected bad hg again..running no thermostat atm to rule things out looking at a car today to buy
i drive a 2002 toyota sienna buy oem there are two ect switch aka engine coolant temperature switch ask the dealer or look it up; then you can start ruling out fuses or relays or wiring. if everything you check is good but the etc switches and you buy the wrong ones fans will stay on even if you buy same make but not the correct model and year. again ask the dealer and make sure it correct. aftermarkets are no good they just make and put any toyota part number made in china. toyota etc switches are made in japan, denso..i learned never buy aftermarket etc sensors. autozone list only two denso models for all toyotas but might not might work for your vehicle. same price as dealer because there oem but are they for your model you will be screwed once installed you can't return.
@@NoneMechanic101 i have a 2010 Hyundai Tucson it started with the fan not coming on at all the car did not run hot or no engine light so i changed pressure temperature switch (H) side and fan came on soon as i started car and didn't go off until i turned the car off i changed 2 relays nothing changed so i changed the coolant temperature sensor same thing do i need to check the fan module or switch? i'm trying to fix this car so my kids can drive it when the come home thank you for any suggestions

Thank you is one of the best thing I heard for my birthday. 👍
Love the way he interacts with his daughter!😎👍
Thank You👍
You’re the one the only one my brother I just replace the engine and the mechanic don’t know what to do thanks for your video
You're so very welcome👍🔧
Have this problem on my 94 celica , I replaced the thermostat & coolant sensor & still does this & overheats a lil bit
I would check the head gasket
@ Non Mechanic 101 My car is a 2016 Hyundai Accent i would like to know if i can turn the ignition swith to on position and turn the compressor on to check if the fan is working?
I myself would put it on the on position. I wouldn't touch any running components.
Question I notice if I start my car I’m the cold in the morning with the heat on the fans run is that normal ?
The fans should start as soon as the car reaches a certain temperature
So the coolant temp sensor is not the sensor that sends info the computer? There is another thing called sender? I have the same issue where the radiator fan is on full speed at start, but when I read the coolant temp with OBD II scanner , its correct and where it should be.

Great video staight to the point real deal!
Thank You. I appreciate it👍🔧
Can you tell me how my rear vents is blowing hot air but it's cold in the front? What will be the reason?
Exactly what I was experiencing and I was right about the sensor
Great. Thank you for watching🔧
I love when people use common sense like you👍
Thank you. I appreciate it🔧

Usually when you turned the a/c on both fans comes on.
Same problem I changed both temperature sensors still fan is spinning on cold engine what should I check next. I got vw golf
I would check the fans wiring
I got this problem too..did you sort your issue out?
Did you guys sort out anything?
plug the code reader in
@@kio51423 Vw has one fan. It will turn whenever AC is turned on, even if engine is cold. AC will turn on when cabin control is set to auto.
Why didn’t you check for current on that plug. Also run straight power to the harness going to the fan. The bottom end.
Didn't think about it

@@Msleelee9487 I would check the wiring and fuses
lol
👍
Save yourself money

I changed both coolant sensors but both fans still stay on. And my engine light stays on
I would check the wiring and the fuses. What is the engine code?
Mine too
