Possible Causes of Cooling Fan Not Working on Ford Five Hundred
There could be several reasons why the cooling fan is not working on your Ford Five Hundred. Here are some possible causes based on the search results:
1. Faulty Heater Blower Motor: The cooling fan may not be working because of a faulty heater blower motor.
2. Coolant Temperature Sensor: The coolant temperature sensor may not be reading the temperature correctly, which can prevent the fan from turning on.
3. Fuse, Relay, or Switch: Issues with the fuse, relay, or switch related to the cooling fan can also cause it to stop working.
4. PCM (Powertrain Control Module): The PCM could be malfunctioning, preventing the cooling fan from operating properly.
Troubleshooting Steps
To diagnose and fix the issue, you can try the following steps:
1. Check the Heater Blower Motor: Verify if the heater blower motor is functioning properly. If it is faulty, it may need to be replaced.
2. Inspect the Coolant Temperature Sensor: Check if the coolant temperature sensor is reading the temperature correctly. If not, it may need to be replaced.
3. Check the Fuse, Relay, and Switch: Inspect the fuse, relay, and switch related to the cooling fan. If any of them are faulty, they may need to be replaced.
4. Verify the PCM: Use a proper scan tool to verify if the PCM is functioning correctly. If it is not, it may need to be repaired or replaced.

Can you drive with a cooling fan not working?

Absolutely not!
Driving for any prolonged period without an operating radiator fan is very likely to overheat your engine and result in an extremely expensive engine repair bill.

What sensor turns on the radiator fan?

Yes, the coolant temperature sensor is an important component in controlling the radiator fan in many modern vehicles. The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the engine control module (ECM), which uses it to determine when to turn on the radiator fan.

Should radiator fan turn on when AC is on?

First, run the AC and see if the radiator fan runs: it’s supposed to run with the AC by default. If it doesn’t run, you likely have a low level of refrigerant in the system or a faulty switch or a sensor, or a bad fan motor, fuse, relay, or a wiring problem.

How do you fix a cooling fan problem?

Step-by-Step Guide to Troubleshooting a Non-Functioning Radiator Fan

1. Check the fuse. If the fuse is burnt, replace it with the same size and type.
2. Inspect the fan’s condition.
3. Test the fan motor.
4. Check the coolant temperature sensor.
5. Test the fan relay.
6. Trace the wiring.

Why is my cooling fan not kicking in?

The most common reasons for a radiator fan not working can be a blown-out fuse, a bad relay, or a broken wire. The faulty coolant temp sensor might also be a reason behind it. Whatever the case, a dysfunctional radiator fan can be fatal.

Does the coolant temperature sensor turn the fan on?

Yes, the coolant temperature sensor is an important component in controlling the radiator fan in many modern vehicles. The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the engine control module (ECM), which uses it to determine when to turn on the radiator fan.

Why is my car AC fan not spinning?

There are usually three main causes of this: damaged cooling fans, an internal obstruction, or an electrical fault. If you suspect one of these problems to be the cause, book an appointment with a mechanic as soon as possible.

How do I know if my radiator fan relay is bad?

The fans don’t start.
If the fan doesn’t work, it won’t cool the radiator. After a while, the coolant will start to heat up and won’t be able to take heat from the engine. In this case, it is most likely the problem will be in the relay as it supplies power to the fan, and without power, it won’t be able to work.

How do I know if my cooling fan fuse is blown?

You might see a temperature light pop up on your dashboard. In this case stop driving immediately. And turn off your car. The fifth symptom is a blown cooling fan fuse.

Is there a fuse for a cooling fan?

On the inside of your fuse box (your car may have more than one) there should be a fuse location marked AUX FAN. This would be for electrical fans that cool the motor over a certain temperature.
