Q: How do you access and replace the various light bulbs on Nissan Altima?
A: To access the front parking/turn signal and side marker lights, detach the plastic inner fender liner at the front edge and pull it back to reach the bulbs; for 2010 and earlier models, the side marker bulb can be accessed from under the hood. Turn the bulb sockets counterclockwise and pull them out of the housing, then remove the bulb from the bulb holder, with installation being the reverse of removal. For the rear turn signal, brake, tail, side marker, and back-up lights, remove the rear trim panel from the trunk interior by taking out the plastic fasteners, then unclip the trunk interior liner to access the rear taillight assembly. Remove the nuts from the studs, take out the taillight assembly by prying it rearward, twist the bulb holder counterclockwise to pull it from the housing, and remove the bulb from the holder, with installation reversing the removal steps. For fog lights, detach the plastic inner fender liner at the front edge, disconnect the electrical connector from the bulb holder, turn the bulb holder counterclockwise to pull it out, and reinstall by reversing the steps. To replace the license plate light, loosen the trunk lid finish panel, twist the bulb socket counterclockwise to remove it, pull the bulb out to replace it, and reinstall by reversing the steps. For the high-mounted brake light, push the housing to the rear, release the front mounting tabs, slide it to the front to release the rear tabs, lift the housing, twist the bulb socket counterclockwise to remove it, pull the bulb out to replace it, and reinstall by reversing the steps. Interior light bulbs are replaced by carefully prying off the lens with a small screwdriver or trim tool, pulling the bulb straight out of its socket, replacing it, and snapping the lens back in place; for the trunk light bulb, release the tab on the side of the lens, pivot it open, and replace the bulb as described. Instrument cluster illumination is contained within the cluster, and if there is a problem with any of its components, the entire cluster should be replaced.
