A simple way to check if the radiator fan is working is to start your engine and turn the air-conditioning system (A/C) to the maximum speed. If the fan is spinning, then it means that the fan motor, fuse, wiring, and relay are all working properly.
What Are The Symptoms Of A Bad Radiator Fan? The most common symptom of a bad radiator fan is an overheating
overheating
Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury.

car engine. You may also notice that the A/C performance is worse than usual and you can sometimes hear some whirring noises coming from the engine bay.
How do you check if a fan is working with a multimeter?
How many ohms should a radiator fan have?
A good motor should read less than 0.5 ohms. Any value greater 0.5 ohms indicate trouble with the motor.

How do you use a multimeter on a fan motor?
In general, you can test a fan motor with a multimeter with these easy steps. First, set the multimeter to ohms and unplug the motor from its power supply to try for a short to ground. Then examine each wire for endless readings. If you receive a reading of 0, you could have a cable problem.
What is a radiator fan resistor?
The cooling fan resistor is an electrical resistor that limits power to the fan in steps, so that the fan can operate at different speeds according to the cooling system’s demands.
The engine-ECU <M/T> or engine-A/T-ECU <A/T> controls the fan controller to activate the radiator fan motor and the condenser fan motor.
What controls the radiator fan to turn on?
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it’s not working, the fan won’t turn on when it needs to, which means the engine might overheat

Where is the relay for cooling fan?
The fan relay is usually located near the bottom of the engine compartment on a metal frame member. The metal acts as a heat sink to keep the fan relay cool. So, unplug the connector at the relay and repeat the check for power. If you get power, you’ve got a bum relay.

Is there a fuse for cooling fan?
Check Fuses
The first thing you want to do when your radiator fan is not spinning is to check the fuses. There will be a large fuse for the fan itself that you want to check. It will be between 30 and 50 amps, and it is usually a larger fuse located in the engine compartment.
A Bad Fuse. It is a very common problem that results in radiator fan failure: the fuse may burn off or simply fall off.
Dead Wires.
Broken Fan Clutch.
Inadequate Coolant Level.
Defunct Temperature Sensor.
Bad Radiator Fan Motor.
Can you drive a car if the radiator fan is not working?
Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.
Should radiator fan run when AC is on?
Q: Should the radiator fan run when AC is on? Yes.Both the radiator and condenser cooling fan are expected to turn on the moment you switch on the air conditioning system. For instance, it is expected for the cooling fan to switch on when the engine carries loads or once it reaches the normal operating temperature.
