When changing a fuse, the first thing you'll need to do is locate your fuse box. Best suggestion for that is to check your owner's manual, but I'm going to show you some common places where they're put in a lot of cars.

On this Pontiac Torrent, which is the same as a Chevy Equinox, there's an access panel right near the passenger side feet. You pull off that door, and you can see right in there, pretty easy to get to all the fuses. On the back side of the door there is a key that shows you which fuse runs which accessory.

Then on a Chrysler PT Cruiser, just as a couple different examples, this is just a little door right here next to the driver's seat. On the back of that door, it may be hard to see, but you can see some writing. That shows you which fuse goes with which circuit. Maybe your taillights or your radio's not working. You look for whatever accessory you might be having a problem with and find the fuse, and then pull it out and check it. We'll put that door back on.

This is a later model GM truck. There's an access door right on the side of the dash as you open the driver's door. You can see some fuses back in there.
A lot of vehicles have fuse boxes underneath the hood. You can see the nice big one here. The little tool that helps you pull them out easily, and then this vehicle has a nice key on the back of the cover. Let's say that the rear defog is having a problem, so you can locate the fuse right there. Find that corresponding fuse. Use your little plastic fuse extractor. Pull it out. You work it back and forth a little bit.

You can see here: a good fuse on the left and a bad fuse on the right. There's a reason you can see through the fuses because that's how a fuse works. It has a little, basically, an electrode or a wire that runs through it that can only handle a certain amount of power. If it gets too much power through it, it blows, and it looks like that.

If you have a blown fuse, very important, it's actually an indicator of a possible larger problem. You could replace the fuse and maybe your vehicle works just fine. If you do replace the fuse and it blows again, that means you have a short somewhere and you need to correct the larger problem, not just replace the fuse.

Now we'll go back. I usually just kind of put the fuse in place, then push it down with my finger. Put our little plastic tool back in place. You don't want to lose that. It makes life a lot easier. Then put the cover back on. I hope this helps you out.
