This question is relating to a previous question I submitted at an earlier time. Why is the system not sending a signal to the relay for the radiator fans to turn on? I've replaced the relay and the fuses are fine.

How do you know there is a lack of signal? You need a scanner that can display live data to see what the Engine Computer is requesting. If it requests the fan to turn on but they don't run, you can also use the scanner to cycle the relay on and off allowing you to take voltage measurements in the circuit.
