Radiator fan is still not working I just got a new radiator and new coolant. Like I said on first questions changed themostat and gasket, sensor by the coolant housing, and even the temperature sensor, checked all fuses and relays and still are good, wired fan directly to battery and works right away . What else can it be? Basically did all that can really be done. Any answers or suggestions

Wiring fault. Could be pinched or a bad ground.

Either that or a relay usually, but you said they were all working.
