Solution

1. Preparation

Gather tools: Flathead screwdriver, multimeter, and a socket set.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Test the Interior Light Switch

Use a flathead screwdriver to remove the cover from the interior light switch.
Check the switch for any debris or physical damage.
Use a multimeter to test for continuity when the switch is pressed. Replace if faulty.

3. Check Door Switches

Open each door and manually press the door switch.
Listen for a click or feel for a spring action. If a switch is unresponsive, it may need to be replaced.
Remove the switch by unscrewing it or gently pulling it out and inspect the wiring for damage.

4. Scan for Error Codes

Use an OBD-II scanner to check for any codes related to the body control module.
If codes are present, diagnose based on the specific code description and repair as necessary.

5. Inspect Wiring Harness

Visually inspect the wiring harness connecting the lights and switches.
Look for frayed wires, corrosion, or loose connectors.
Repair or replace damaged wiring as needed.

6. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Test the interior lights by opening and closing the doors to verify they operate correctly.
