1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery negative terminal to prevent any electrical shorts.

2. Inspect Door Switches

Remove the door panel using a socket set and trim removal tools.
Locate the door switch; it is typically mounted on the door frame.
Disconnect the electrical connector from the door switch.
Use a multimeter to test the switch for continuity when pressed and released. Replace if faulty.

3. Inspect Overhead Light Switch

Remove the overhead light assembly using a flathead screwdriver to release clips.
Inspect the switch for signs of sticking or failure.
If the switch is malfunctioning, replace it with a new switch that matches the OEM specifications.

4. Check Wiring and Connections

Follow the wiring harness from the overhead lights to the fuse box.
Look for any frayed wires or loose connections. Repair or replace any damaged sections.
Ensure all connectors are clean and securely attached.

5. Reassemble Components

Reinstall the overhead light assembly and door panels.
Reconnect the battery, starting with the negative terminal.

6. Test the System

Open and close all doors to verify that the interior lights function correctly and turn off as expected.
Monitor for any error codes using the OBD-II scanner after repairs.
