I have two fans; one fan doesn't work the other comes on when using the A/C.The relays are good, the fuse is good and the fan works when you put direct current to it.Checked wiring ,no open or short in wires. could it be a temperature sensor?

Good afternoon,

Did you check voltage at the motor itself when the other comes on?

I attached a wiring diagram for you to view.

Check the fuses listed for power on both sides.

Also, remove the connector for the coolant temperature sensor with the key on. It should kick on the coolant fans. You have 2 sensors so do it to them both.
