It only comes on when I turn the AC on. What's happening when I engage the AC is that both the radiator fan and AC fan come on and run. When I turn AC off, both fans shut off.

So because of this I've ruled out the motor is not bad since it works when AC is on.

What is my next step?

Thanks!

 

Found the issue. One of the 2 wires with the plug that plugs into the fan switch at the bottom of the radiator are broken.
