1. Blown fuse: A blown fuse can cause the radiator fan to stop working.
2. Bad relay: A faulty relay can also prevent the radiator fan from functioning properly.
3. Broken wire: A broken wire can disrupt the electrical connection and prevent the fan from working.
4. Faulty coolant temperature sensor: A malfunctioning coolant temperature sensor can fail to send the signal to activate the radiator fan.
5. Low coolant level: Insufficient coolant can lead to overheating and cause the radiator fan to stop working.
6. Damaged fan: The fan itself may be damaged and need to be replaced.
Steps to Diagnose and Fix the Issue
To diagnose and fix the problem with your Dodge Neon’s radiator fan, you can follow these steps:
1. Check the coolant level: Ensure that the coolant level is sufficient. Low coolant levels can cause the engine to overheat and prevent the radiator fan from working properly.
2. Inspect the fuse: Check the fuse related to the radiator fan and replace it if necessary.
3. Test the relay: Test the relay responsible for controlling the radiator fan. If it is faulty, replace it.
4. Examine the wiring: Inspect the wiring connected to the radiator fan for any signs of damage or disconnection. Repair or replace any broken wires.
5. Verify the coolant temperature sensor: Test the coolant temperature sensor to ensure it is functioning correctly. If it is faulty, replace it.
6. Consider the fan clutch: If your Dodge Neon has a fan clutch, it may be worn out and need to be replaced.
7. Seek professional help: If you are unable to diagnose or fix the issue yourself, it is recommended to consult a qualified mechanic or technician for further assistance.
Remember, these steps are general guidelines, and it is always best to consult the specific repair manual for your Dodge Neon or seek professional help for accurate diagnosis and repair.

How do I know if my radiator 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.

At what temperature should radiator fan kick in?

about 200 degrees Fahrenheit
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.

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 I know if my cooling fan switch is bad?

Check Engine Light and Overheating
Intermittent aside, if your check engine light comes on while you’re driving, it could mean your cooling fan switch is failing.

What activates the radiator fan?

The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.

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.

What would cause a radiator fan to stop working?

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.

Can I drive car if radiator fan is not working?

Can I Drive My Car If The Fan Is Not Working? Yes, your car can still run without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to the engine’s performance and lifespan. Every time your engine overheats, you’re causing tremendous damage to the precious engine.

Can a bad thermostat cause fan not to come on?

An unlikely, but possible, cause is a bad thermostat. Try turning the Fan switch to the “On” position to see if the blower comes on. Watch the video. If the blower operates in the “On” position and does not operate when the air conditioner is running, you may have a bad thermostat.

Why is my radiator fan not engaging?

It could be a problem with the fan motor, temperature sensor, fan control relay, or wiring. The Check Engine Light might come on. With modern cars, a DTC will be triggered that illuminates the light on the dash when it exceeds normal operating temperatures. It might be accompanied by a message on the cluster too.
