Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during electrical work.

2. Inspect the Interior Light Switch

Locate the interior light switch (usually on the overhead console).
Verify the switch position is set to "door" or "auto."
If the switch is faulty, replace it with a new one.

3. Test and Replace Door Switches

Check each door switch by manually pressing it while the door is open.
If a switch remains stuck or unresponsive, remove the faulty switch:
- Tools Required: Flathead screwdriver, socket set.
- Sub-steps:
  - Gently pry off the switch cover.
  - Disconnect the wiring harness.
  - Install the new switch by reversing these steps.

4. Inspect Wiring and Connectors

Visually inspect wiring harnesses leading to the door switches and interior lights.
Look for signs of wear, fraying, or corrosion.
Repair any damaged wiring or connectors as needed.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the interior lights by opening and closing the doors to ensure they function correctly.
