Check the computer codes and see if there is any code referring to the engine coolant temperature sensor.
Check both fan fuses, cool fan one and two both in the under hood fuse block.
There are also three fan relays in that same under hood fuse block.

Hello PACHYAUTO63,


PATENTED_REPAIR_PRO suggested in his post to check the computer codes. I am sending you a link that if you decide to conduct the scan yourself it will be a great help to you. The link features an article with written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com
