How to Replace the Fog Light on an '05 Sentra
- 1). Climb underneath the front bumper. You should have just enough room to see what you are doing without having to jack up the vehicle.
- 2). Remove the screw that is facing downwards towards you at the fog light housing assembly.
- 3). Apply leverage to the two metal posts sticking out of the top of the fog light housing assembly with a long, flat-blade screwdriver. This should push the entire housing forward.
- 4). Remove the white plug running to the back of the fog light assembly.
- 5). Turn the bulb collar counterclockwise to unlock it from the housing and pull it straight out.
- 6). Install the new bulb. Installation is the reverse of removal.
