I have two fans to cool my radiator but one won't come on and my car starts to run hot
Which one is working?... the one on the right or the left? The one on the right is for the Air Conditioning (primarily).. the one on the left (driver's side) is for cooling the engine (coolant). If the one on the driver's side isn't working, check to see if there is power (battery voltage) and ground to it (the ECU turns it on when the coolant temp is above 208 degrees). If you have power & ground at the cooling fan connector, then the cooling fan motor is bad.
