Remove the bolts, remove offending fan and replace with new one

Bad waterpump, stuck thermostat, bad electric fan, or a plugged radiator.
under the throttle body.
Could be a bad temp. sensor not telling the fan to turn on, or a bad motor. Try jumping the motor to see if the fan comes on. If not, its the motor.
Bad fans or the sensors that tell the fan when to kick on are bad.
The heater fan is under a panel under the glove box- unclip this panel and the heater fan is right there
Replace the fan blower resister
The radiator fan sensor switch or the radiator fan motor are at fault (maybe even both). Wire the fan motor direct to see if it will run, if it does, replace the sensor switch. If the fan motor doesn't run, replace the fan motor before you buy a new sensor. If after replacing the fan motor, the fan still doesn't run, then replace the sensor.
