Identifying the Fuse Location
Replacing a cigarette lighter fuse is a straightforward task that can be completed in a few minutes. However, before you start, it’s important to identify the location of the fuse.
The location of the fuse can vary depending on the make and model of your vehicle. In most cases, the fuse will be located in the fuse box, which is usually found under the dashboard or in the engine compartment. To find the fuse box, consult your vehicle’s owner’s manual or look for a small, plastic box with a cover that says “Fuses” or “Electrical.”
Once you’ve located the fuse box, you’ll need to identify the fuse that controls the cigarette lighter. This can usually be done by referring to the fuse diagram that is printed on the inside of the fuse box cover. The fuse diagram will list each fuse and its corresponding function. The fuse that controls the cigarette lighter will typically be labeled as “Cigarette Lighter” or “Power Outlet.”
Once you’ve identified the fuse that controls the cigarette lighter, you can remove it from the fuse box using a pair of needle-nose pliers. Be careful not to touch the metal contacts on the fuse, as this could damage the fuse or the fuse box.
