Hi everyone

My 2017 Rc 300 F has chosen that it no longer wants to be cooled and does not turn on its radiator fans...
Yes, i have checked the coolant and water levels. My water radiator works fine, and the AC blows cold and the heater blows hot. Overtime I get an overheating warning...
Here is the catch. The temperature seems to be working on the dash—starting off on low and increasing as the car works. I have checked the fuses with a multimeter, they work. I have changed the fan control module (it may be faulty as a check engine light decided to join) and I also put in a new relay just to be safe. The top and bottom radiator hoses get hotter the longer the car runs, and the fans work when connected with direct current. What can the problem be?
Also , semi related, kind of not, I bought a coolant temperature sensor, but I can't seem to figure out where it goes. Does anyone know?
