2017 cooling fans running continuously

[zane]

I have a 2017 Exped XL XLT 3.5L eco boost. The cooling fans were running continuously on high almost immediately after starting the vehicle. Figured it was a faulty cooling temperature sensor or TCS…trouble is, I can’t find the thing. Can someone help me with the location on the engine? TIA!

Hi @zane have you figured that out? My fans are on max once I start the engine and never turn off. Same year Expy

Did you ever find what caused this? Mine is doing the same thing.

Under what circumstances is this happening? Try starting the vehicle on a cool morning with the HVAC system set to off and see what it does.

2017 Expedition Cooling Fans Loud. On High When A/C is on.

So I am getting annoyed and so far have not found a permanent solution. After start up with A/C on usually a few seconds later my electric cooling fans will kick on super hi mode. Sounds like a semi-truck. Very loud fan noise. They are working properly just kicking on in a seriously high...
