How to Replace a Fuse?
2 Answers
Locate the fuse position according to different car models. Generally, the fuse box is near the battery. The fuse box is usually secured with clips. Carefully refer to the diagram to identify the fuse. Before removing the fuse, read the diagram carefully. It is usually easier to match the diagram on the side where the fuse is easily accessible. Replace it with a new one. The fuse box usually comes with spare fuses. Use tweezers to remove the fuse and check if it is blown.
When the headlights of your car, like my old clunker, don't light up, I'd guess it's a blown fuse. Locate the fuse box under the driver's seat or under the hood, open it up, and you'll usually find symbols on the back of the cover corresponding to each fuse. Use a small pair of pliers to gently pull it out and take a close look—if the metal wire inside is broken, that means it's blown. Head to the hardware store to buy an exact replacement with the same amperage rating; never mix and match a 10A with a 20A, or you'll mess up the circuit. When inserting the new fuse, listen for a crisp click, then test if the headlights are working again. Make sure to turn off the engine and remove the key during the process—safety first! It’s a good idea to keep a few spares in your toolbox so you’re not scrambling if you break down late at night. Most importantly, figure out why it blew—whether it's due to unstable voltage or aging wiring—so it doesn’t happen again too soon.
