Checking and Replacing Fuses

Fuses and fusible links protect your vehicle’s electrical system from short-circuiting or overloading. If electrical parts in your vehicle are not working, the system may have been overloaded causing a blown fuse. Before you replace or repair any electrical parts, check the appropriate fuses.

Be sure the ignition switch is pushed to the OFF or LOCK position and all switch are OFF.
Open the fuse box cover.
On the fuse diagram, find the number of the fuse you want to check. The diagram tells you where to locate the fuse on the panel. Pinch the fuse perpendicularly with the fuse puller and pull it out.
To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse with a new one.
If a new fuse also opens, have the electrical system checked and repaired by a Nissan dealer or a repair facility of your choice.

Notice

Never use a fuse of a higher or lower amperage rating than that specified. This could damage the electrical system or cause a fire.
Never replace a broken fuse with anything other than a new fuse (such as wire, foil, etc). Use always an intact fuse of the same color.
