Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked safely and on a flat surface.

2. Inspect Door Switches

Locate the door switches on each door.
Remove the door panel if necessary to access the switch.
Disconnect the switch and test it with a multimeter to ensure it opens and closes properly.
Replace any faulty switches with new ones.

3. Check Interior Light Switch

Locate the interior light switch on the ceiling or dashboard.
Verify that it is set to the 'door' or 'off' position.
If the switch is faulty, remove it and replace it with a new switch.

4. Examine Wiring and Connections

Inspect the wiring harness leading to the door switches and interior lights for damage.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and verify that the interior lights turn off when the vehicle is off and doors are closed.
