Fuses. How Do Know They Are Burned Out And How To Change Them

You can easily spend more money than you need to if you get a mechanic to look for an electrical problem in your car without checking your fuses first. Your cars electrical system is protected by the fuses that are located in the fuse block and that could be the only problem with the component that is not working.

Sometimes your radio won’t come on, some of the lights won’t work, or wipers quit working for no reason. Some cars and trucks even have an overloaded system on the ignition that can act like starter problems. You can spend a massive amount of time trying to run these problems down if you don’t take the time to check the fuses in your electrical system first.

Rancho Smog Temecula brings you this tip, before you take your car in for a costly fix you must at least take the time to check the fuses in the fuse block to see if there is a problem at that point.  A blown fuse could be the source of numerous different troubles, and you might end up saving a lot of money if you catch it yourself.


The only thing you need for the job is the replacement fuses.

The fuse panel of the car is placed just under the steering column which you can find easily.

Open the fuse panel by pulling the cover. This is easily done with your finger.

Now you need the fuse diagram of the car to locate the fuse you need to replace. This is available on the underside of the fuse panel cover.

Remove the burnt fuse using the puller of the panel. This is done by clipping the correct end of the fuse puller to the fuse that is to be removed. You must securely grab the fuse with the fuse puller before pulling the correct fuse out of the fuse panel.

Now press the new one into the slot of the panel and make sure that the metal part of it is sunk all the way into the panel.

Other Things That Are Good To Know:

The fuse makes a bridge circuit from the power supply to the circuit being powered. Occasionally it joins several powered objects. For instance, your horn, running lights, and brake lights could all be powered by just one fuse.

A fuse can only manage so much power before burning out to protect the items being powered in the circuit. Fuses work on the same principle as a surge protector. When a power surge runs through the fuse, it blows without allowing the excess power to melt your wiring or expensive electrical gadgets in your car that might not stand up to the load.

Fuse is a very cheap item that is easy to install and replace but it does a great service to the car by preventing damage to the very expensive electrical and electronic components preventing repairs that will cost a lot. But, in case you are confronted with a blown fuse you need to replace it and you must know how to do it.

One Last Thought

Fuses are designed to protect your electric components before they are damaged if there is a fault in the electric system.  If you have one fuse that  burns out more than once you should check with your mechanic to make sure there isn’t a more serious issue that needs to be repaired.
