This automotive maintenance tutorial was specifically written to assist owners of the sixth generation "B16" (2007, 2008, 2009, 2010, 2011 & 2012) Nissan Sentra sedan in checking or changing a blown fuse or relay in either the engine bay or interior passenger compartment electrical panels.

Owners of other Nissan vehicles such as the Versa, Cube, Altima, Maxima, Leaf, Pathfinder, 370Z, Juke, Rogue, Xterra, Murano and Quest may also find these DIY instructions to be helpful.

This 2012 Sentra is equipped with "low profile" mini blade fuses. They can be replaced with either OEM style low profile fuses or the slightly taller standard mini blade fuses.

You can purchase new low profile mini blade fuses on Amazon.

A white plastic fuse puller tool is included on the interior passenger compartment electrical panel.

Fuse Location Diagram
Pull Out Front Two Clips
Pull Out Two Rear Clips
There are two fuse panels in the engine bay on the right (driver) side next to the 12V automotive battery.

To release the cover on the front panel, press in the release tab on the side and the other one on the front.

Lift the fuse box cover straight off and turn it over to view the fuse location diagram.

The 2nd engine bay fuse block is located just behind the front one.

Gently pull out the two plastic clips on the front and the two clips on the rear to release the block from its case.

Fuse Location Diagram
Open the storage compartment and squeeze together the two side walls to release it from the dashboard.

There is a fuse location diagram sticker on the rear of the storage drawer.

There are also fuse location diagrams inside your owner's manual.


Interior Fuse Panel
Plastic Fuse Puller Tool
Place Tool Over Old Fuse
There is a white plastic fuse puller tool in the center of the interior electrical panel.

Pull the tool straight out of the fuse block and place the smaller end over the fuse you'd like to check or change.

Pull Out Old Fuse
Drop Fuse Out of Tool
Hold Fuse Up To Light
Pull the old fuse straight out of the panel and hold it up to a light source.

If the thin metal bar inside the translucent plastic center of the old fuse appears to be broken or "burnt" then the fuse is most likely "blown" and should be replaced.

If the thin metal strip inside the fuse appears to be intact, then the fuse is probably still good.

Although since new fuses are so inexpensive, it should still be replaced as part of your electrical issue troubleshooting process.

This 2012 Sentra S is equipped with the newer style of "low profile" mini blade fuses.

Assortment boxes of replacement fuses in a variety of amperage ratings (e.g. 5, 10, 15, 20, 25 amps) can be purchased at stores such as Pep Boys, Napa Auto Parts, Advance Auto Parts, Carquest, Walmart or online at

The slightly taller standard mini blade fuses can also be used in vehicles with low profile fuses.

Push In New Fuse
Flip Over & Close Panel
Push On Fuse Box Cover
Push a new fuse of the same amperage rating straight in to the socket.

Test to see if the electrical component that wasn't working is now operating properly.

If a new fuse didn't solve the problem, then there might be a shorted wire or the component itself will need to be replaced.

If you suspect that a relay is faulty, the easiest way to check it is to simply replace it. Or you could test it with a digital multi-meter tool.

Flip over the engine bay fuse block and push it down in to its case.

Replace Fuse Puller Tool
Re-Insert Storage Compartment
Close Storage Drawer
Gently push the front engine bay fuse box cover down in to place.

Push the fuse puller tool back in to its storage holder on the interior fuse panel.

Re-insert the storage drawer in to the dashboard and close it.

Be sure to record the fuse change in your vehicle's service records.
