What causes cooling fans not to come on?
Six things may prevent an electric cooling fan from coming on: ... Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay. A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)
Why wont my fans turn on in my car?
If there's a voltage from the fan to the relay, the chances are that the fan may be faulty and needs to be replaced. The sensor reads the system's temperature and determines when to turn the fan on. If it isn't functioning properly, chances are that the fan won't turn on, and the vehicle may overheat as a result.
What makes radiator fan come on?
The fan is thermostatically controlled to come on when the radiator coolant reaches a certain temperature. You car's cooling system is probably compromised - either low coolant (due to leaks) or a thermostat problem or radiator issue.
When should your engine fan kick on?
Fan Trigger
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.
Does radiator fan come on with AC?
In a nutshell: The radiator fan comes on so the A/C works at its highest efficiency. The A/C condenser (the part which sits in front of the coolant radiator) is a heat exchanger.
How can you tell if a fan fuse is blown?
Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
What happens when radiator fan doesn't work?
What happens if the cooling fan stops working? If your cooling fan stops working, your engine could overheat. This could cause damage to your engine parts. It's a serious issue and needs to be looked at by a garage.
Can you drive a car if the radiator fan is not working?
As such, you should never drive your vehicle if the cooling fan isn't working even though you can. ... If the radiator does not have cool air blowing on it constantly, it will overheat eventually, so you'd need the perfect combination of weather and traffic to drive effectively without a radiator fan.
