Radiator fan will not run but motor is good

Check Maxi fuse #3 60 amp in the under hood electrical center #1 .This is power for the #1 cooling fan . Also check the #1 fan control relay in the same under hood electrical center .
These vehicles use 2 360 mm (14.2 in) cooling fans to aid air flow through the radiator. Electric motors drive the cooling fans. These motors are attached to the radiator. Motor size varies with each engine option.
A coolant temperature switch activates the fan motors. This switch regulates voltage to the cooling fan relay. This switch operates the fan whenever the engine coolant temperature exceeds 110°C (230°F). For location and diagnosis, refer to Electrical Diagnosis. A transducer can also activate the circuit, depending on the A/C compressor head pressure going to the condenser.
The engine cooling fan relays provide the high current required for the cooling fan motors using a low current signal coming from the Powertrain Control Module (PCM). This signal is a function of various inputs.
Refer to Electrical Diagnosis for further information and diagnosis of the cooling fan relay.
Electrical Center #1, Underhood (U/H)
RH side of the engine compartment, forward of the strut tower

In the under hood fuse / relay box ! There are three of them COOLFAN/relay 1-2-3 . It's marked on the under side of fuse box lid .
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block.

Replace the fan relays. The Radiator Cooling Fan Motor Relay is located: Under hood, driver side, front side of strut tower, mounted in relay panel
Application:
High speed The Radiator Cooling Fan Motor Relay is located: Under hood, driver side, front side of strut tower, mounted in relay panel
Application:
Low speed,here's a new part.

test the motor with a jumper wire from the battery

REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.MAKE SURE COOLANT NOT LOW.IF ALL IS GOOD CHECK FOR LEAKING WATER PUMP WEEP HOLE IF LEAKING REPLACE WATER PUMP.MAKE SURE COOLING FANS RUNNING.IF ENGINE RUNNING HOT WHILE SITTING LONG TRAFFIC LINE AND COOLANT NOT RUNNING.CHECK COOLANT FAN RELAYS AND FUSE.IF ALL IS GOOD HOT WIRE MAKE SURE COOLING FAN MOTOR GOOD IF COOLING FAN DONT RUN WHEN HOT WIRED FAN MOTOR BAD.IF FAN MOTOR OKAY AND FUSE RELAYS GOOD YOU HAVE FAULTY COOLING FAN WIRING.YOU COULD HAVE BAD ENGINE COOLANT SENSOR OR FAULT IN ECM CODE SCAN TO CHECK THEM BOTH.CHECK ENGINE OIL.LOOK LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF OIL LOOKS OKAY.YOUR ENGINE BLOCK, RADIATOR AND HEATER CORE NEED FLUSHING.

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.

First check the fuse,then check to see if the coolant level in the radiator is low,then if you can check the cooling fan relay,and the cooling fan motor to make sure it is good,if all this checks out fine,then replace the coolant sensor,and bleed the cooling system of all the air in it.

CHECK COOLING FAN FUSE AND RELAY.IF BOTH ARE GOOD.HOT WIRE COOLANT FAN.IF FAN DONT RUN FAN MOTOR NEEDS REPLACING. IF FAN MOTOR RUN WHEN YOU HOT WIRE IT.YOUR FAN MOTOR ELECTRICAL WIRES DAMAGED OR HAS SHORTS OR THE COOLANT TEMPERATURE SENSOR FAULTY.

You have a radiator fan motor that is not running either due to a thermostatically controlled temp switch,(Located on the back of the radiator) a failed fan relay (in the engine compartment fuse /relay box) or a bad fan motor.
You can troubleshoot by checking for 12V DC to chassis ground at the fan motor temp switch. If you have power in you can jumper with a wire the switch wires and see if the fan runs. If it does not run then you need to check the fan relay and motor.

To test the fan you can run a wire from the battery to the fan and another wire to chassis ground to see if the fan runs. If after directly connecting 12V DC to the fan motor and it does not run the fan has failed.

As far as the you either replace it with another one or... have to figure out which 2 wires control the fan motor and jumper them out to see if the fan runs.

This sounds like the cooling fan motor was the real problem, when it does this the motor is partially shorted, this overheats the new fan relay and will burn it out, I think most likely they should have caught this when the fan relay was replaced, now the motor and the relay should be replaced, as the new relay may be damaged. Also make sure the electrical connector to the fan motor is not burnt, if it is then replace it along with the motor.
