Replace your temperature sensor. There is a sensor specifically for the cooling fans that triggers the relays, and tells the fans to turn on/off. The relays won't energize unless it gets a signal from that sensor.

The only other things would be the coolant temp sensor or the engine computer. Alot of the new GM's have the on and off function of the cooling fans controlled by the computer. If the coolant temp sensor is ok, then most likely the problem is in the engine computer.

The first thing I would check would be the temperature sensor that sends a signal to the relay to turn the fan on. Of course make sure you have plenty of water in the radiator or the sensor won't work at all. I have seen anti-freeze come through the sensor and corrode the wires shorting them out. So it could be broken wires, unplugged wires or a bad sensor. I am not sure exactly where the sensor is at on the Pacifica but your local parts store could show you. It is usually in the intake or cylinder head.
