The fans will not come on, but work when straight wired to the battery

Hello,

An inoperative cooling fan can be due to a faulty relay, bad wiring, malfunctioning coolant sensor or a bad fan motor.

First check the relay. On this vehicle it is called the solid-state fan relay or SSFR.
It is located on the left front inner frame just behind the radiator (see diagram below)

Here is a guide on how to test relays:

If the relay is good, then the issue could be bad wiring of a faulty coolant temperature sensor.
Malfunctioning coolant temperature sensor will be unable to send the correct data to the ECM to turn on the fan.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
