"Dave Erb here from Dave's Ultimate Automotive in Austin Texas and we're going to be talking about replacing an automotive fuse. Now, periodically you'll have a fuse that blows, most of the time for minor reasons such as a dime maybe falling down inside your cigarette lighter or something of that nature and you'll need to replace the fuse. On most cars today you'll find two fuse boxes, one's going to be inside the car either in one of the kick panels, down by your feet, or just inside where you open the door, it'll have a trim colored panel on it. Inside it'll also be a ledger, let you know which fuse is which and there's usually a little tool inside to help you change the fuse. The ones outside are most responsible for the things that are outside under the hood, some of your bigger relays and bigger fuses for multiple things, will be out here but same way you'd replace from inside as you would outside. You'd identify which fuse needs to be replaced, you take your tool, it's like little tweezers, the smaller ones are the most common ones that need to be replaced. You simply clip on, squeeze and pull. Make sure you use the proper rating fuse. Sometimes you'll even find extra fuses inside these houses, these don't have them but a lot of times you'll find them, and then you just get the proper rated fuse fifteen amp, twenty amp, whatever it might be and slide it right back in the slot that it came out of, force it down, put your lid back on and you're good to go."
