What causes a fuse to blow on a cooling fan?
Blown fuse A blown cooling fan circuit fuse is another symptom of a potential problem with the cooling fan motors. If the motors fail or surge, they may cause the fuse to blow in order to protect the rest of the system from any sort of damage due to electrical surges. The fuse will have to be replaced to restore possible functionality to the fans.
What happens when the motor on a cooling fan fails?
If the motors fail or surge, they may cause the fuse to blow in order to protect the rest of the system from any sort of damage due to electrical surges. The fuse will have to be replaced to restore possible functionality to the fans. The cooling fan motors are an important component to any cooling fan assembly,…
How does the cooling fan relay work on a car?
The cooling fan relay is the relay that controls the engine’s cooling fans. When the correct parameters are met, a temperature switch or the computer will activate the relay, which will allow power to the fans. The relay will usually be activated once it is detected that the vehicle’s temperature…
Why does my car have a radiator fan?
Virtually all late model vehicles and the vast majority of road going vehicles use radiator cooling fans with electric motors to keep the engine cool.

What does the relay on a cooling fan do?
The typical electric cooling fan circuit includes a temperature sensor, a relay, a control module and the fan motor. The relay is the component that fails most often; so be sure to test the relay as well as its power supply and ground connections.
Why are my cooling fans running at all times?
3. Cooling fans stay on at all times. If the cooling fans are staying on at all times, this is another (less common) symptom of a possible problem with the cooling fan relay. If the relay shorts internally, it may cause power to be permanently switched on, which will cause the fans to run at all times.
Can a radiator fan and condenser fan share a relay?
There are, however, some models that use a dedicated second unit to the condenser. In such a scenario, the condenser fan and radiator fan may or may not share the same relay. If the cooling fan does not engage, you can check whether the relay is to blame by swapping it out for a different relay.
What happens if you have a bad cooling fan relay?
The check engine light illuminating may indicate a faulty cooling fan relay. A faulty cooling fan relay can also negatively affect air conditioning (A/C) performance. The reason being, on most vehicles, is that the cooling fan doubles as a condenser fan.
