How to replace an auto fuse

Cars and trucks use fuses for many different components. Every now and then, one of the fuses will blow. You can take your car to a mechanic if you want, but it will be much cheaper to replace the fuse yourself.

Replacing a fuse is different for every vehicle, but the same general procedure applies. The first thing you'll have to do is get a replacement fuse. Open your vehicle's fuse box (typically either underneath the steering wheel or under the hood -- your owner's manual can tell you exactly where) and locate the blown fuse. All fuse boxes should include a diagram that tells you which fuse controls which components, so you can tell where the blown fuse is. If you have a circuit tester or multimeter, you can test the fuse to verify that it has been blown.

Once you've found the bad fuse, get a replacement fuse of exactly the same size and rating. Most auto shops or hardware stores sell fuses, typically in variety packs for a couple of dollars.

When removing the old fuse, you can use your fingers or a pair of tweezers, or you can get a specially-made fuse extractor (which is just a fancy pair of tweezers). You can also use needle-nose pliers, but if you do, be careful not to squeeze too hard and crack the fuse.

Make sure the car is turned off when removing or installing a fuse. Put the new fuse in gently, facing the same direction as the old fuse. Once it has snapped into place, close the fuse box and turn the car on. Test the component that the fuse controls and verify that it works. If it doesn't, the fuse may not be pushed in all the way, or the new fuse may be bad.

how to find short circuit

Different circuits needs different ways. You can start by checking which fuse gets blown when replaced and check what circuit that fuse supplies it's power to. That will narrow down your search to within that circuit. Next remove all components that are connected to the circuit. Replace fuse again. If it still blows, that means that the supply lines is shorted to ground. REMEMBER. Fuses gets blown when its supply line is shorted to ground. If fuse does not blow, connect each component one at a time. The component that blows the fuse once connected is the one that is short circuited.

How can I test if a sensor or sensor pigtail is good or bad?

you should first start by finding out what components are on the circuit which keeps blowing the 10amp fuse.
before inserting a fresh fuse check all components and see if wiring has a dead short to ground.
disconnect all the components that the 10amp fuse feeds. insert new fuse into fuse box and turn igntion on.
now reconnect each connector to each component and see if you blow the fuse. when the fuse blows again when you reconnect a component you now know its that component or wiring causing the problem.
you can now test the component (sensor or actuator or solenoid) to see if its a component failure or a wiring problem.

My 1998 tahoe keeps blowing a fuse in the relay box I need a wiring diagram so I can locate the short

There are MANY diffrerent wiring diagrams so in order to narrow down which diagram you need, I would need to know which fuse is blowing and will be happy to help. If you know which componants this fuse controls you may want to start by disconnecting the different componants first to see if that stops it before you start chasing wires. You can let me know which fuse keeps blowing so I can get you the correct diagram by replying here or feel free to email me directly at csautomotivecars@att.net with all your information.

to fix the fuse i need mechanic or myself i can fix it .windows, cd, meter everthing closed

look in your manual for location of the fuse panel, there is generally a small one under the hood and a larger one inside the car under the dashboard or in the end of the dashboard. you can replace the fuse, however when one blows it is there to protect the car wiring from a bad component. so when you replace the fuse, the bad component will just blow it again and most likely replacing that component will be a job for a mechanic. sounds like you have a large amperage fuse out, those are usually under the hood.
