Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flashlight.
Disconnect the battery to ensure safety during electrical work.

2. Inspect and Replace Door Switches

Locate Door Switches: Identify the door switches typically located in the door jamb.
Remove Switches:
- Use a socket set to unscrew the switch if necessary.
- Gently pull the switch from its housing.
Test Switch Functionality:
- Use a multimeter to check for continuity when the switch is pressed.
Replace Faulty Switches:
- If a switch is faulty, install a new switch.
- Ensure it is seated properly and secure it with screws.

3. Check Interior Light Control

Inspect the Control Switch:
- If equipped, verify the interior light switch is in the correct position (usually set to "door").
Test the Circuit:
- Use a multimeter to ensure that power is reaching the light control circuit.
Replace Control Switch if Necessary:
- If defective, disconnect the old switch, and connect a new one.

4. Reconnect Battery and Test

Reconnect Battery: Ensure all connections are tight and secure.
Test the System: Close all doors to verify if the lights turn off.
