A fan failure, or a failure of the fan relay or control circuit is bad news because it can allow the engine to overheat.
Five things may prevent an electric cooling fan from coming on:
ELECTRIC COOLING FAN QUICK CHECKS
- Defective temperature switch or coolant sensorEngine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan)
- Failed fan relay
- A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)
- Bad fan motor
One way to quick check the fan circuit is to start the engine and
turn on the A/C to max. If the fan runs, the fan motor, relay, fuse and
wiring are all okay. But this test doesn't show if the temperature
switch or temperature sensor and PCM are energizing the fan when coolant
temperatures are high.
To check the temperature at which the fan comes on, turn the A/C off
and keep the engine running until it reaches normal operating
temperature. Most fans should come on when the coolant reaches about 200
to 230 degrees. If the fan does not come on, something in the control
circuit is defective. Resistance checks should then be made on the
temperature sensor or switch, and a voltage check on both sides of the
relay (you will probably need a wiring diagram of the fan cooling
circuit on your vehicle to identify the relay terminals and wiring
The fan motor itself can be checked by using jumper wires. Unplug the
wiring connector on the fan, and use the jumper wires from the battery
to route power directly to the fan. If the fan motor is good, the fan
should spin at normal speed when supplied with 12 volts. Noisy bearings
or a slower than normal speed would indicate a worn motor.
