Fan motor do not work

Check the fan motor coming on when you turn your A/C on if fan motor is not coming on then could be the fan motor itself or the wires.

IF COOLANT FAN FUSE AND RELAY OKAY.HOT WIRE COOLANT FAN TO SEE IF FAN MOTOR OKAY.IF FAN MOTOR OKAY.THE ENGINE COOLANT TEMPERATURE SENSOR MORE LIKELY BAD.THE ENGINE COOLANT SENSOR WHEN ENGINE COOLANT GETS HOT IT CAUSES ENGINE COOLANT TEMPERATURE RESISTANCE TO DECREASE CAUSE COMPLETE CIRCUIT IN WHICH POWER FROM PCM TO ECT SENSOR WILL SENT POWER TO COOLANT FAN RELAY THEN CAUSE COOLANT FAN TO TURN ON. HAVE ECT SENSOR OR ENGINE COOLANT TEMPERATURE SENSOR CHECK USING CODE SCANNER TO MAKE SURE ITS WORKING BEFORE SPENDING EXCESS MONEY.

COOLING FANS DONT TURN COULD BE FAULTY FAN RELAY.FAULTY PCM AND FAULTY COOLANT TEMPERATURE SENSOR.CODE SCAN FOR FAULTY PCM CODE AND A FAULTY COOLANT TEMPERATURE SENSOR.SEE IF ENGINE COOLANT TEMPERATURE SENSOR IS GIVING CORRECT COOLANT TEMPERATURE USING A CODE SCANNER.IF ENGINE IS 190 DEGREES AND THE ENGINE COOLANT TEMPERATURE SENSOR READING 100 TO 80 DEGREES COOLANT SENSOR IS BAD.HOT WIRE COOLING FAN TO SEE IF FAN MOTOR WORKS.BECAUSE COOLING FAN MOTOR COULD HAVE OPEN CIRCUIT CAUSING ELECTRIC MOTOR NOT TO TURN ON.

the cooling fans on your car are comanded on by the engine control module which reads engine temperature from the temperature sensor . when comanded on the engine control module sends a signal to the cooling fan relays . which in turn runs the current to the cooling fans . So you might want to check the cooling fan relays and make sure the fues for the cooling fans are good and the relays .if the cooling fan fuses and relays are good it could be a problem with the fan motors or the engine control module not reading the right temperature in that case it could mean you have a problem with the temperature sensor

It is failure of the thermostat , failure of the fan/motor or failure of the fuse/relay in the section. The thermostat will detect the increase in temperature as the posisitor triggers the fan relay to clicks and work the fan to cool, when it comes to desired temperature the relay cuts off till the temperature builds up.
So it is irrespective if the car moves or idles.

IF CAR OVERHEATING AT STANDSTILL OR IDLING IN A LONG TRAFFIC LINE.COOLANT FAN NOT TURNING ON.MORE LIKELY COOLANT TEMPERATURE SENSOR NOT WORKING.USE A SCANNER TO CHECK COOLANT TEMPERATURE WHEN ENGINE HOT.IF TEMPERATURE READ LOW COOLANT TEMP.SENSOR BAD.IF SENSOR OKAY.CHECK COOLANT FAN FUSE AND RELAY.ALSO HOTWIRE FAN TO SEE IF FAN MOTOR WORKING.IF NO REPLACE FAN MOTOR.IF FAN MOTOR GOOD FUSE AND RELAY COOLANT FAN MOTOR WIRE CONNECTOR IS DAMAGED OR HAS BROKEN WIRE.

SCAN CAR FOR A FAULTY COOLANT TEMPERATURE SENSOR.IF SENSOR GOOD CHECK COOLING FAN FUSE AND RELAY.IT BOTH OKAY.HOT WIRE COOLANT FAN USING JUMPER WIRES TO BATTERY IF FAN DONT WORK REPLACE THE FAN MOTOR.IF COOLANT TEMPERATURE IS BAD REPLACE IT.BECAUSE IT CONTROLS THE FAN TURNING ON WHEN COOLANT GETS A CERTAIN TEMPERATURE.

Your heater blower, inside the car works to provide heat to the interior of your car, and the air is hot, right? If the cooling fan is not coming on, depending on the outside ambient temperature, you may be using your heater coil for the heater to dispell suficient heat (inside the car), combined with a low outside temperature to keep the engine at normal operating temperature negating the need for the cooling fan. OR your coolant temperature sensor is bad, and the ECU doesn't know that the engine is hot and to turn on the fan. This sensor works by changing the voltage returned to the ECU depending on the temperature of the tip, which changes the resistance to the computers inquiry. So, the computer knows the temp of the coolant. It uses this information to adjust mixture gauge etc. Most now have 2. One for the gauge, and another for the ECU. So don't go by the gauge working. Then there is the fan motor itself. This can be tested by using a testlight on the wires when the engine temperature gauge in at 3/4 to the hot side of the gauge. The other way to test is to bring a live wire to the motor. If the motor is good, the sensor is bad, if the motor is bad, well the motors bad.

CHECK FUSE AND RELAY.IF ALL IS GOOD.HOT WIRE COOLING FAN USING JUMPER WIRES.USING CAR BATTERY.IF FAN RUNS.ITS GOOD.IF FAN DONT RUN.REPLACE FAN ELECTRIC MOTOR.ALSO SCAN IT. TO MAKE SURE COOLANT TEMPERATURE SENSOR IS NOT OPEN.MAKE SURE ENGINE COOLANT TEMPERATURE SENSOR AND COOLANT TEMPERATURE READS SAME ON SCANNER IF NOT REPLACE THE COOLANT TEMPERATURE SENSOR. SEE IF COOLANT TEMPERATURE IS BAD THE COOLING FAN OR FANS WONT RUN.

Check your thermostat and check to see if the electric motor has power or not may be a damaged wire or a fried fan motor,you can also check the fan motor by running a power lead from your battery.good luck
