Can a radiator fan be connected to a wire?
This terminal cannot be used for the fan because it is designed to carry low amperage from the key, and if the fan is attached to it, a fire could result because the wire is too small for the amperage required. The fan must have a 10-gauge wire to carry this amount of amperage.
When to turn on the radiator fan switch?
When the switch is turned on, the power is sent back to the relay, through the relay and to ground, which activates the switch. The fan switch should be left on except when cruising. When the vehicle comes to a stop and no air is moving through the radiator, the fan should be on.
What do I need to troubleshoot a car radiator fan?
Modern vehicles use the electronic control module (ECM-car computer), powertrain control module (PCM), or a dedicated fan control module (or both) to control the operation of the radiator fan, and can be little more complicated to troubleshoot sometimes.
Where does the power come from on a radiator fan?
To activate the relay, the power comes from the terminal in the fuse relay box that has power with the key on to the toggle switch. When the switch is turned on, the power is sent back to the relay, through the relay and to ground, which activates the switch. The fan switch should be left on except when cruising.
What causes a radiator fan to fail on a new car?
Wiring issues. Although new cars are not immune to wiring problems, radiator fan failures due to issues with wiring are more likely to occur on older vehicles. Long-term exposure to heat, vibration, moisture, and corrosion can cause connections to go bad, or wiring insulation to become brittle and flake off, leaving wires exposed.
Can a car run if the radiator 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.
How do you wire a fan to a battery?
Take the second jumper wire and connect one end of the jumper wire to the positive wire from the fan. Extend the other end of the jumper wire over to the positive terminal of the battery. When the wire touches the positive terminal of the battery, the fan should come on.

What does it mean when your radiator fan is not working?
This is what we call a blown fuse. A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan.
