This automotive maintenance tutorial was specifically written to assist owners of the third generation (2011, 2012, 2013, 2014 & 2015) Kia Optima in checking or changing a blown fuse or relay in either the engine bay or interior passenger compartment electrical panels.

Owners of other Kia and Hyundai vehicles with similar fog light bulb housings such as the Forte, Cadenza, Rio, Soul, Sedona, Sorento, Sportage, Sonata, Accent, Elantra, Veloster, Azera, Tucson, Santa Fe and Genesis may also find these DIY instructions to be helpful.

Replacement low profile mini blade fuses in a variety of amperage ratings (e.g. 5, 10, 15, 20, 25) can be purchased at retail store such as Wal-Mart, Pep Boys, Napa, Advance Auto Parts or online at Amazon.

A white plastic fuse puller tool is included at the middle rear section of the engine bay fuse block.

The engine bay fuse box is located at the right rear area of the engine bay closest to the driver's seat.

Press in the release tabs on the front and rear of the cover before pulling it straight off.

There is a fuse location diagram included on the underside of the cover and also another one in the owner's manual.

Pull out the white plastic fuse puller tool from the middle rear area of the fuse panel.

Pinch the end of the tool to open the jaws and place them over the fuse you'd like to check or replace.

Pull Out Old Fuse
Hold Fuse Up To Light
Push In New Fuse


Pull the old fuse straight out of the socket and hold it up to a light source.

If the thin metal bar inside the old fuse appears to be intact, then it is most likely still good.

If the thin metal strip inside the center of the old fuse appears broken or burnt then the fuse is "blown" and needs to be replaced.

Since new fuses are so inexpensive, the old fuse should be replaced as part of your electrical issue troubleshooting process.

Push a new low profile mini blade fuse of the same amperage rating (e.g. 5, 10, 15, 20, 25) straight in to its socket on the panel.

The interior passenger compartment fuse panel is by the driver's left knee behind a rectangular plastic cover.

To remove the cover, insert your fingers in to the opening at the bottom of the cover and pull it out.

There is a fuse location diagram provided on the back side of the cover and also another one in the owner's manual.
