Ford Contour 97

Good afternoon, I have a 1997 Ford Contour and the problem is that the cooling fans aren't turning on. Both fans have been tested directly and they are working. The thermostat, radiator, temperature sensor, and even the relays that control the fans have been checked and are in good condition. Any tips or solutions to this problem?

Look for pin 68 of the computer between 80 and 90 degrees C; a pulse should arrive there, which is what activates the fan motor relay.

I forget to note that it is 6 cylinders and automatic transmission with 2.5 engine, the same computer pins as a 4 cylinder and 2.0 motor ??
