How can I test if my engine cooling fan is working?
That’s why you will need to test it. Unplug the fan connector closest to the fan. Make up some jumper cables. Then connect them directly, from the battery to the fan motor, to see if it spins. Consequently, if it does not spin it is blown.
How to troubleshoot an electric cooling fan problem?
1.Has the Cooling Fan Actually Failed? 1 If the fan comes on when the AC is running at MAX, but doesn’t run when the engine is hot, check the temperature sensor… 2 If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may… More …
How does a radiator fan work when the AC is on?
The electric radiator cooling fan assembly is controlled by a thermoswitch located in the side of the radiator. At higher coolant temperatures, the switch closes to start the cooling fans. Any time the coolant temperature rises to higher than normal levels, the fan will start and continue to run until coolant temperature returns to a normal range.
What causes a car cooling fan to run continuously?
2. A cooling fan temperature switch (or sensor, in some vehicles) can also get stuck, which may cause the fan to run continuously any time you turn the ignition key on or start the engine. Troubleshoot the switch. 3.

Why are the cooling fans not working on my car?
Many other issues can cause the engine to run hot or overheat. Rather than uncommonly high engine temps, the driver may notice that the cooling fans have stopped running. A faulty or broken relay cannot deliver power to the cooling fans. In turn, the unpowered fans won’t run, leaving the radiator to its own devices.
Why do you need a cooling fan relay?
It helps move air through the radiator even if the vehicle is not in motion. The cooling fan helps move air through the radiator even if the vehicle is not in motion. Most modern vehicles have electric fans that are controlled by relays, which are vital to keeping the engine cool.
Do you have to turn on the fan to test a car?
Another important point to note when testing is that the engine must be running to check the fan operation. With the sensor disconnected the STOP light operates immediately the ignition switch is turned BUT it does not bring the fan on. This requires the engine to be running.
How can I Check my fan status?
Restart the computer and press F12 at startup. The Diagnostics does have a check on the fan speeds. Welcome to Dell Community! This is a Dell User Forum.

What does it mean if your radiator fan is not working?
If the radiator fan is not working, it’s a serious problem. Just because the radiator fan is not on does not mean that it is not working. They are designed to only run when needed. If your Cruze is running hot, and the fan is not running we’ve laid out the most common causes of this issue below.
How can I test my AC fan motor?
To test the fan motor on your air conditioner, you’ll have to do a continuity test. Click here for a video tutorial. Before you start, make sure the thermostat is set to cool and that the temperature setting is as low as it will go. Step 1. Check the power

Why is my radiator fan not turning on?
The fan will turn on after the temperature reaches about half. Usually comes on when the car is standing still due to the small amount of air circulating through the radiator. No the AC will turn the radiator fan on to pull air across the condensor.
Why is my engine cooling fan not working?
Your engine cooling fan, only runs when needed to help cool the engine. So, a engine cooling fan, relay or control circuit failure is bad news. Because, it can allow the engine to overheat. The engine coolant sensor or a separate engine temperature switch, is used to monitor engine temperature.
Why does my radiator fan run full speed when I start the car?
Immediately upon starting the car, the radiator fan begins to run full speed, even though the car is stone cold. The AC is OFF. The radiator and condenser are BRAND NEW. This problem existed before and after the radiator was replaced. The fan continues to run at its maxiumum speed, regardless of the engine temperature.
What are the symptoms of a bad cooling fan relay?
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.
Is it bad if the fan motor is not running?
Keep in mind that just because the fan motor isn’t running, doesn’t mean it’s bad. If the power supply is fine and the windings are in good shape, check the capacitor next. The capacitor helps the fan motor run.
What happens when an engine cooling fan fails?
The engine cooling fan only runs when needed to help cool the engine. So, A engine cooling fan failure; or a failure of the fan relay or control circuit is bad news; because it can allow the engine to overheat. The engine coolant sensor or a separate engine temperature switch is used to monitor engine temperature.
Why is my radiator fan clutch not working?
The fan clutch is responsible for attaching the radiator fan to the engine and makes it work. If this clutch goes broke, the fan won’t work. It is the usual wear and tear over the years that may cause the springs in the clutch to corrode or even burn out. If you cannot find any other radiator fan problems, the clutch is most likely the cause.
