2013 Dodge ram 1500 tradesman 4.7 liter. Is it equipped with a radiator fan mod

Hard to say. The manual I looked at said "if equipped" - so perhaps it's not on all vehicles. I'd say if it's missing -- it didn't suddenly become missing unless someone tampered with your vehicle. If the overheating did not always happen but is now -- then I'd say it's not the fuse. For overheating ensure the fan works - check inlet and outlet temperatures from the thermostat. Make sure there is no debris in the way of the radiator for proper air flow. https://repairpal.com/auto-repair-near-me#&zipCode=
