Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Tools Required:
- Multimeter
- Screwdriver set
- Wire brush (if corrosion is present)

2. Inspect Door Switches

Remove the panels covering the door switches if necessary.
Check each switch for physical damage, dirt, or corrosion.
Clean the switch contacts with a wire brush if corrosion is found.
Reinstall switches and panels once inspected.

3. Test and Replace Faulty Switches

Use a multimeter to check continuity of each door switch:
- If no continuity is found with the door closed, the switch is faulty.
Replace any non-functional door switches with new components.
Ensure the new switches are properly seated and secured.

4. Check Interior Light Settings

Review the vehicle's interior light settings in the infotainment system.
Reset any automatic settings that may keep the lights on.
Test the interior lights after adjustments to confirm they operate correctly.

5. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure all tools are removed from the engine bay and vehicle interior.
