Solution

1. Preparation

Gather necessary tools and equipment.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Door Switches

Locate the door switches on each door.
Use a multimeter to check for continuity in the switch when the door is closed.
If a switch is malfunctioning, remove it and replace it with a new part.

3. Check Interior Light Switch

Locate the interior light switch, which may be on the overhead console.
Ensure it is in the "off" position.
If the switch is faulty, remove the console cover, replace the switch, and reassemble.

4. Test Wiring and Connections

Visually inspect wiring harnesses connected to the interior lights for frays or shorts.
Use a multimeter to check for proper voltage at the light sockets.
Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and observe the interior lights to ensure they turn off when the engine is off.
