This automotive maintenance tutorial was specifically written to assist owners of the eighth generation (2016, 2017, 2018 and maybe also the 2019 and 2020 model years) Nissan Maxima sports sedan in changing a burnt out courtesy step light bulb located at the bottom of the interior plastic interior door panel.

Owners of other Nissan or Infiniti vehicles such as the Versa, Altima, Juke, Rogue, Rogue Sport, Murano, Xterra, Pathfinder, Sentra, Cube, Armada, Leaf, Quest, Frontier, 370Z, GT-R, Titan, Kicks, NV, NV200, G25, G37, M35 and M37 may also find these DIY instructions to be helpful.

The compatible replacement miniature wedge base light bulb part number is 194.

You can also use a brighter 194 LED bulb.

The only tool needed to access and replace the light bulb is a small flathead screwdriver or a plastic pry bar tool.

Gently Pry Out Housing

The first two steps are to open the door and then move to the bottom edge of the plastic interior door panel.

To prevent from scratching the plastic surfaces, you may choose to either cover the tip of your screwdriver with a thin microfiber cloth or instead use a plastic pry bar tool.

Gently insert the blade of the screwdriver in between the top edge of the light housing and the door panel.

Carefully pry out the light housing.

Try to avoid using excessive force. The light housing should pop out relatively easily.

Remove the light housing from the door panel.
