HI. This will, generally, be the result of the cooling
The cooling fan switch on most electric fans monitors coolant temperature signals from the engine control computer. When the engine is cool, the switch opens to keep the fan from spinning. When the engine is warm, the switch closes, thus, turning the fan on for cooling.
I would advise to Inspect the cooling fans(thermal switch)
,wires and connections. Cooling fan switch problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the switch itself. If the wires or connections are bad, replace them. If you think the switch is defective, it should be tested.
The electric fan cooling switch, or thermal switch, can be tested by placing the element in a bucket of water. Heat the water to approximately 207°-216°F (97°-102°C)
and connect the switch leads to an ohmmeter(make sure to keep the switch leads out of the water)
. The switch should have no continuity until the temperature reaches this level. Let the water cool off below 207°F (97°C)
and the switch should lose continuity. If the switch has no continuity at any temperature, replace it.NOTE_The thermal switch is located on the top of the radiator, usually on the passenger side.
