Hello,
The radiator fan is controlled by a control module and a relay.
The control module is mounted on the back of the fan (see picture below).
The relay is located in the fuse block under the hood.
First you want to check the relay and verify it is good.

If the relay checks out then check the control module.
Remember to only work on the radiator fan area when the engine is cool. Also always be careful working around a radiator fan.
I have attached the testing procedure for the module for your reference.
Please let me know of any questions.
Thank you.
