This details will help.

Thanks.

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.

Removal & Installation To Remove:

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Remove or disconnect the following:
   • Radiator upper crossmember
   • Fan motor electrical connector
3. Drain cooling system below the level of the upper radiator hose.
4. Remove or disconnect the following:
   • Upper radiator hose from radiator
   • Radiator fan fasteners and upper clip
   • Fan assembly by lifting upward to clear radiator

To Install:

1. Install or connect the following:
   • Radiator fan assembly
   • Upper clip and fasteners
   • Upper radiator hose to radiator
   • Fan motor electrical connector
   • Radiator upper crossmember

hi..the radiator cooling fan(s) will be replaced by
disconnecting the power (an automotive connector)
then physically unbolting it from the radiator.vehicles
with less room in the engine compartment might require
pulling the radiator, fans and all and then disconnecting it.
check it out..
thank u..
