WHY WON'T RADIATOR FAN COME ON? CAR OVERHEATING

1998 Mercury Marquis

Bought a 98 marquis drove it home next day started it up after about an hour car began to overheat popped the hood noticed the radiator wasn't coming on. Changed sensor, thermostat & radiator and all fuses & relays still nothing.

Power the fan motor direct from the battery and see if it turns on-if so -Could be the computer controlled circuit of the fan relay

Did that and the fan works that way. So if it is the computer controlled circuit how would I fix that?

Check the wires back to the computer for shorts/open circuit if okay-think! Computer
