Radiator Fan Motor
The fan motor brushes frequently seize due to moisture and silt ingress through the motor's breather snorkel. This mechanical resistance prevents the armature from overcoming static friction even when current is applied. In many cases, the brushes wear unevenly or become stuck in their holders, breaking the electrical circuit within the motor assembly itself.

Fan Circuit Breaker
This is an inline protective device located within the wiring harness, often referred to as a 'thermo fuse' in technical forums. It is prone to internal corrosion or fatigue of the bi-metallic strip, which creates an open circuit that prevents power from reaching the fan motor. Because it is hidden in the loom, it is frequently overlooked during standard fuse box inspections.

Coolant Temperature Sensor
The ECU relies on a specific resistance range from this NTC (Negative Temperature Coefficient) thermistor to trigger the fan relay. If the sensor's internal ceramic element degrades or develops a high-resistance film, it will report a lower-than-actual temperature to the ECU. This prevents the logic gate from reaching the 'Fan ON' threshold, even as the engine approaches a critical overheat state.
