Hello,
Since you have already replaced the motor. You could have a faulty fan relay or defective wiring.
First you want to check the relay. The relay is located under the hood in the battery junction box (see diagram below).
Here is a article on how to test the relay:

Then you want to check to see if you are getting power to the fan.

I have attached diagnostics as well as wiring diagrams for your reference.
Please let me know of any questions.
Thank you.
