Bad temperature sensor
Bypass (jump) sensor - trigger point is
180 degrees F
The temp sensor provides a ground to the fan.
With the key in the “on” position, test by using a
jumper wire from any solid ground point to the
sensor.
Caution:
ensure fan and fan blades are clear, fan

Bad relay
Replace relay
Ensure the relay has proper ground and voltage.
Replace relay if issue persists.
Loss of 12v power supply
Inspect wire harness and post
connections, corrosion should not be
present on any terminals
Make sure there are no cracks or breaks in the
copper solenoid bracket, and battery
posts/connections are tight and free of debris.
Test solenoid using a multimeter or other device,
check the batter for proper voltage.
