I am not sure if my fan is suppose to be on all the time but my engine was hot and my fan did not turn on. i am trying to figure out if it could be a fuse or what it could be.

Hello,

You could have a faulty fan motor, 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 and replacement procedure of the fan motor for your reference.

Please let me know of any questions.

Thank you.
