What Makes a Fuse Keep Blowing In Car? Learn How to Fix Blown Fuses
Are your lights or wipers not working? It could be because of a blown fuse in the fuse box. When this happens, you have no way of powering some electrical components. If you often find that the fuse keeps blowing in the car more often, then you need to find the fault and fix it. Get to learn more about what would cause a fuse to blow.
What is the Function of a Fuse
Before we get to understand why the fuse keeps on blowing, let's get to know more what a fuse is all about. A fuse is an important electrical component inserted in circuits, and you get blown to prevent damage to an expensive component.
Before a fuse gets to blow, it comes with a rating in terms of current amperes. Whenever there is more current than the system would handle, then the fuse element would melt and thus disconnecting the current from flowing.
What this means that you do not get any power to the different electrical components in line with that blown fuse. Until when you get to find the fault and fix it, then more fuses would end up getting blown as a preventive measure.
What Causes the Fuses to Keep Blowing
A number of things can lead to a fuse keeps blowing in a car and all have to be checked and repaired to avoid spending more on the fuses. The common issue with fuses blowing would be because of faulty wiring.
The faulty wiring or even the defective wiper motors would often lead to the excessive current flow in a system. What this does is result in a blown fuse each time a new one is installed. If the motors cannot be repaired, then you might have to replace them entirely.
Having defective switches is another way of ending up with short circuits. The short circuit is not a good thing for the fuse, which would find it as a fault thus blowing in the end. It is the same thing for a shorted motor; it would end up causing a shorted motor.
What Next for a Blown Fuse
There are a number of ways this could go when it comes to dealing with a blown fuse. The important thing is to understand what is causing the fuse to keep blowing. The simple fix is often replacing the blown fuse and test the car again. If the fuse does not blow, it might be an easy fix because there was a power surge in the system.
For the case of where there has been a continuous blowing of the fuses, it is important that you do a thorough check for the wiring connection to find some of the loose connections and deal with them.
You should also pay attention to the battery leads making sure that there is a secure connection that keeps the car electrical components running correctly.
Now that you have identified some of the things that can use the fuse to keep blowing, it is important to learn how to replace the fuse in a car.
How to Replace a Fuse in a Car
The process on overall is quite simple and it would be done within minutes. You would simply have to pull out the blown fuse and replace it with a new one. One thing you have to keep in mind is to replace the blown fuse with one having the same ampere rating.
Here is a quick video on how to replace the blown car fuse.
As you can see, the overall process of changing a fuse is no trouble. Instead of taking the car to a mechanic to do the repairs, you can do it on your own at home. You can always share comments or questions below under the comment section if you need any more information.
