How do i know if a fuse is blown - 1999 Chevrolet Lumina

If you don't know what number fuse it is , how do you know it's blown ? Do yourself a favor , take it to a qualified repair shop.

If you do not know where it is or what it looks like than how do you know it is blown?

It is not difficult to visually look at a fuse to see whether or not it is blown. a visual inspection can be done with a flashlight and without removing any fuses from the fuse block. A blown fuse will typically have a black spot and an open in the wire between the two posts.

A test light can also be used to quickly identify blown fuses. if one side has power and the other side does not the fuse is no good.

Your owners manual will also help you identify fuses. In the back you will find the index. Look under fuses and it will give you the page numbers. If you do not have an owners manual one can typically be downloaded on the manufacturers website. Just look for an "owners" link usually near the top of the page.

using a test light check the fuses with the key on as some fuses are only powered when the key is on. check both sides of the fuse.

If you suspect a blown fuse, i suggest that:

Instead of wasting time searching for the exact location, why not just remove each fuse 1 by 1, and replacing them as you go so you don't mix them up. If you have any blown fuses, you will find it in under 30 seconds. If you don't know the difference between a good vs blown fuse, ill post a picture to help you identify.



If your car has the round clear fuses with metal caps on each end, then blown ones will be burned black.

is the cigarette lighter working if so it may be the one on the radio its self. can blow the radio fuse and not the main fuse. radio fuse is less think it is 5amp as main fuse can be 15-20amp fuse.

If you do not know which fuse it is, how do you know the fuse is blown?
