Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Test Door Switches

Sub-steps:
1. Remove the door panel to access the door switch. Tools required: socket set, trim removal tools.
2. Disconnect the wiring harness from the door switch.
3. Use a multimeter to test for continuity. Press the switch; it should show continuity when pressed and none when released.
4. If faulty, replace the door switch with a new one.

3. Check Overhead Light Settings

Sub-steps:
1. Locate the overhead console where the interior lights are controlled.
2. Ensure the switch is set to the "Door" position, not "On" or "Off."
3. Test the lights after adjusting settings.

4. Inspect Body Control Module (BCM)

Sub-steps:
1. Locate the BCM under the dashboard (usually near the driver's side).
2. Check the connectors for corrosion or loose connections.
3. If damaged, replace the BCM with a compatible unit.
4. Reconnect the battery and recheck the interior light function.

5. Final Assembly and Testing

Sub-steps:
1. Reassemble the door panel and overhead console, ensuring all screws and clips are secured.
2. Reconnect the negative battery terminal.
3. Test the interior lights by opening and closing the doors.
