Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Test Door Switches

Tools Required: Multimeter
Steps:
1. Remove the door panel from one of the affected doors using a socket set and trim removal tools.
2. Locate the door switch, which is usually found near the door latch.
3. Disconnect the wiring harness from the switch.
4. Using the multimeter, check for continuity in the switch when pressed (it should show continuity when pressed and no continuity when released).
5. If faulty, replace the switch with a new one.

3. Check Wiring and Connections

Tools Required: Wire stripper, electrical tape
Steps:
1. Inspect the wiring connected to the door switches for any signs of wear, fraying, or disconnection.
2. Repair or replace any damaged wiring to ensure proper electrical connection.
3. Secure all connections and use electrical tape to insulate exposed wires.

4. Verify Lighting Control Settings

Steps:
1. Turn on the vehicle ignition and navigate to the vehicle settings on the dashboard display.
2. Look for interior lighting settings and ensure that the automatic feature is enabled correctly.
3. Adjust settings if necessary to allow lights to turn off after closing doors.

5. Reassemble and Test

Steps:
1. Reattach the door panel securely, ensuring all clips and screws are fastened.
2. Reconnect the negative battery terminal.
3. Test the interior lights by closing all doors and checking if they turn off automatically.
