the cooling fan will only come on if the air conditioner is on. If the air isn't on the fan wont come on until the car is overheating

Hello,

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.
