Here you go for the circuit. I found a good article that offers some good suggestions too. If you want a dash switch too, hook it in 'parallel' with the thermostat switch (hook to each side of thermostat)
Take a look here:

How to test and replace radiator cooling fan.


Hi.

Here a tip illustrating steps to test and replace the radiator cooling fan and the parts that may cause cooling fan malfunctioning.

Before replacing the fan, make sure that the fan is really faulty.
Read volts at fan contacts or jump the fan wiring to energize the fan directly.Ensure that fan blades are not blocked.

If the fan is OK, then the faulty part is either thermostat or fan relay.Ensure also that you have tested the 15A fuse in the junction block and the 40A fuse located in the Power distribution Center (PDC).

Here a diagram showing the location of the fan relay:

Finally, here below the steps required to replace the fan. The procedure is quite simple.

  • Disconnect the battery negative cable and set it apart.
  • Disconnect the electrical connector to the radiator fan.
  • Undo the bolts that hold the top fan housing and fan assembly (this is called Radiator Shroud).
  • Remove the Radiator Shroud housing.The radiator shroud will come out with the fan sliding toward the top side.
  • Install the new fan performing the operations in reverse order.

Here a diagram showing radiator shroud and cooling fan assembly:

Overheating when I sit idle.


Over heating the engine is a serious concern. With the hood raised you should hear the motorized fan turn on just behind the radiator as the engine requires additional cooling.. If you look in from the rear of the radiator you should see the fan blades.

This electric powered motor operates on a thermostat and when the engine temperature rises this fan should come on. I'm assuming from your description that when driving and air is flowing through the radiator as the car travels the engine is nor overheating.

Check fan motor thermostat, check fan motor and check wiring.

Motor engine cooling fan only runs as engine temperature requires additional cooling.

Car over heats


Check and see if the Radiator cooling fan is working. It should cycle more or run continuously when the AC is on. There are often 2 heat sensors for the Temperature, 1 is for the gauge and the other is for the Radiator fan.

Just having water flow is not enough to cool the engine, the electric Radiator fan makes a big difference. There should be a Relay in the Powerbox. You can get Diagrams for the wiring at Autozone.com when you register for FREE. Then you will be able to tell what is in the Powerbox and get chassis wiring diagrams.

Since you had a new radiator installed, there is a possibility that the electric fan was not reconnected.

Cooling fan burned up


Get a new fan motor and blade from GM or from an aftermarket supplier.

GM parts are usually better than the aftermarket ones, though for fit and functioin.

May also look into checking the relays and harness. If the terminals of the fan show they are getting current, then the motor will have to be replaced if not turning or obviously burnt.

Good luck on this repair.

Inspect/Replace

CAUTION
The fan that draws cool air across the radiator can be driven by either a belt or electricity. Rotating fans can be dangerous. Some are controlled by an automatic switch and can start unexpectedly. When working on electric fans, keep in mind that electric cooling fans should be disconnected when working around them.
When replacing a radiator fan motor, always refer to the vehicle's service manual. The following is a general guide for cooling fan replacement.

  • Disconnect the negative battery terminal at the battery. This is necessary on vehicles using electric fans, but some vehicles may require the relocation of the charging system components.
  • Drain the cooling system.
  • Loosen or remove the hose clamps, then remove the upper and lower hoses from the radiator.
  • Disconnect the transmission cooling lines and plug them off, if equipped.
  • Disconnect the electric fan motor connector, if equipped.
  • Remove the fasteners attaching the fan module to the radiator.
  • On some vehicles equipped with air conditioning systems, it may be necessary to discharge the system. This is the case if the radiator and condenser can not be separated in the vehicle.
  • Remove the upper radiator cross member or mounts.
  • Disconnect and plug the air conditioning lines at the condenser, if needed.
  • Remove the radiator and fan module as one unit if possible.
  • Separate the fan module from the radiator.
  • If required, separate the radiator from the condenser.
  • Remove the old fan module.
  • Install the new fan module onto the radiator.
  • Reattach the fasteners attaching the fan module to the radiator.
  • If equipped, connect the electric fan motor connector.
  • Reinstall the radiator.
  • Refill the cooling system.
