Diagnosis after Locating the Faulty Fuse
You don’t just want to go about loosening up your car without any actual foresight of what you want to achieve. If you suspect that it is the fuse that is faulty, then you want to locate it first. Make sure that you have the right set of instruments that will aid you in your quest. When a circuit in your car has a lot of electricity passing through it, it is the fuse that bears this consequence. It was designed to protect other parts of your car from becoming damaged; it does so by taking in the excess electricity and blowing up to avert serious damage.
One of the best ways to know if your car’s fuse is dysfunctional is if the electrical parts of your car cease to function. That is to say that the radio stops functioning, the windows stop rolling on or up, and all your lights go off in concert.
But it is worthy of note that if your car’s electrical components have been progressively growing worse; then, it might just be the fuse that is the problem. But then, there is no harm done checking out if it is.
Locate the Fuse Panel
Alright, you now know for certain that the fuse of your car is the problem. So what is your next step? Of course, it is to find out the exact position to avoid causing unnecessary stress for yourself.
Most of the car models built recently position their fuse panel somewhere in the dashboard, under your steering, by the driver’s side. But then, different manufacturers have their choice of where to situate it.
When you locate it successfully, gently remove the fuse panel cover, and right there will be different fuses that are somewhat color-coded, all plunged into the panel. Together with the numbers that were marked on them, all of these color-coded fuses serve to specify different current ratings. These ratings show the amount of current that is meant to pass through them.
If you bought the car fairly recently or if you are the type that is very careful with your belongings, you probably have the manual of your car lying somewhere in your home. Fetch it and check it out to know where the fuse is located.
There is normally a pictorial representation of the set of fuses somewhere behind the fuse panel that depicts which of the fuses directly correspond to a particular electrical component.
You may have misplaced your car manual.
If that is the case, then the best thing to do is reach out to a dealership. To do this, you can simply run a quick internet search and select the dealership that is very close to you. They’ll furnish you with every detail you need to know, like the specific fuses and the fuse panel type that is best for you. Feel free to check out another dealership if you think you are not getting the right information from a particular dealership.
It is also very important that you try running a test on the fuses before properly taking them out. After removing the cover of your fuse panel, look for the fuse puller. Many of the cars around have small fuse pullers, but it is ok if yours do not come with one.
Before taking out the fuses, ensure that you’ve done that test. Testing it with an ohmmeter/multi-meter and continuity test light will show you if it is still working.
After opening up the cover, there should be some fuses that you suspect are the faulty ones. These are the ones you should try testing first. Use the two testing methods to test the fuses without removing them, i.e., the multi-meter or test light, by placing them on the two small-sized metallic tabs situated at the fuse’s top.
Sometimes, it can be somewhat tricky to connect to these tabs. Still, as soon as you are certain that the test probes are making contact with that metallic part of the fuses, and the probe lights up (continuity test light) or indicates on the meter (ohmmeter), then there is nothing wrong with the fuse.
Suppose any of the two tools stated above are not readily available.
In that case, you can utilize the fuse puller located in your car’s fuse panel, a set of small pliers, or even your fingers to remove the fuse; take one visual inspection at the fuses to ascertain which of them are still functional or damaged. Sometimes, the bad fuses may be marked by some black spots indicative of something that is burnt. Go ahead and replace the bad fuses.
Fuse Replacement after Removal
When you are attempting to replace a damaged fuse, ensure that you use a fuse with an identical current rating as the one you are replacing.
Check out the fuse panel illustration and the rated color-coded fuses; lastly, check out the manual of your car to assist you in determining the right current rating of the new fuse.
Proceed to gently push the fuse into the right fuse slot. Ensure that it is installed before placing the panel back into your car.
Take one look at the circuit again. As soon as you’ve finished replacing the damaged fuse, turn your car’s ignition to know if your new circuit is functioning correctly. If yes, then you’ve fixed the problem. If no, then you may need to see a car mechanic.
