How to Replace Door Light Bulbs 02-09 Toyota 4Runner

Difficulty: Beginner · About 15 min · Toyota 4runner

Replace a door courtesy light bulb on a 2002–2009 Toyota 4Runner by removing the lamp housing, changing its bulb, and reconnecting the door wiring.

Steps

1. Remove the door light housing

   Carefully pry the courtesy lamp from the door trim and disconnect its electrical connector. Use a protected tool to release the lens from the housing without cracking it.

2. Replace the bulb

   Pull the old bulb straight out of its socket and install a new 194 bulb. If it is stuck, use pliers with light pressure so the glass and socket are not damaged.

3. Reassemble the courtesy light

   Press the lens onto the housing and reconnect the wiring plug. Align the housing with the door opening and press it into the trim until its retainers hold.

Check your vehicle’s repair manual for exact specifications and fit.
