Solution

1. Preparation

Gather tools: multimeter, screwdriver set, and flashlight.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Door Switches

Locate the door switches: These are typically mounted in the door frame or on the door itself.
Remove the door panel (if necessary):
- Use a screwdriver to remove screws and gently pry off the panel.
Test the switch:
- Disconnect the switch and use a multimeter to check for continuity when the switch is pressed.
- If faulty, replace the switch with a new one.

3. Check Wiring Harness

Visual Inspection: Examine the wiring harness connected to the door switches for any frayed wires or corrosion.
Repair or replace damaged wires: Use electrical tape or solder as necessary to ensure a solid connection.

4. Configure Interior Light Settings

Check the vehicle manual to verify the correct setting for interior lighting.
Some vehicles have a switch to turn the interior lights off; ensure it is set correctly.

5. Reassemble and Test

Reattach the door panel: Ensure all clips and screws are replaced correctly.
Reconnect the battery: Reattach the negative terminal and ensure it is secure.
Test the interior lights: Close all doors and check if the lights turn off automatically.
