How do you know if a fan relay fuse is bad?
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.
Why do my electric fans keep blowing fuses?
Usually there is a relay contact between the fuse and the motor. If it blows with the relay open, check the wiring downstream of the fuse. Use an ohmmeter to check each wire to ground with the ignition off. If the fuse does not open immediately, it indicates there is an overload rather than a dead short.
Which fuse is for cooling fan?
The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly behind the radiator.
How do you check a fan fuse?
The first step is checking for a blown fuse. Most newer cars have a different style of fuse that uses a plastic housing; with the fusible link encased in the housing. So, the easiest way to check it is visually. Check it for a continuous wire with no breaks. Using a multimeter is another good way.
Is there a fuse for the fan?
The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module. Remember that if the fan fuse is blown – there might be a problem with the wirings or the radiator fan.
How do you test a fan motor relay?

What happens when the fuse on a fan melts?
Like the circuit breakers in your house, these fuses are designed to break the electrical connection when too much electricity causes your fan to overheat. When the fuse melts, it breaks the connection and cuts power to the fan. Check the cord and the inside of your fan for this fuse.

How can I tell if my floor fan has been tripped?
To do this, open your breaker panel and look to see if the circuit breaker has been tripped. You’ll be able to tell because the thick, black switch will be moved to the “off” position. If you’re not sure which circuit controls which rooms, just check to see if any are out of place.
