Still cant get electric fans to kick on.I have replaced several sensors and relays nothing has worked. Bleed the air out of the system.I can let it sit in driveway at idle with heat on stays bout half way on gauge cut the heat off it starts going up an the fans never do kick on. (Temp switch, coolant temp sensor, cooling fan switch, thermostat, and radiator cooling fan relay have all been replaced) What in the hell could I be missing?

Sounds like the computer is not getting an input signal to read the engine temperature to energize the fan relay or its defective
