Solution

1. Preparation

Gather tools: flathead screwdriver, multimeter, socket set, and a replacement fuse if needed.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Door Switches

Remove the door panel using a flathead screwdriver and socket set to access the door switch.
Disconnect the electrical connector from the door switch.
Use a multimeter to check for continuity when the switch is pressed and released. If faulty, replace the switch.

3. Check Overhead Light Switch

Locate the overhead light switch and verify it is in the correct position (typically "door" mode).
If malfunctioning, replace the overhead light assembly with a new one.

4. Inspect Wiring Harness

Visually inspect the wiring harness connected to the door switch for frays, cuts, or corrosion.
Repair or replace any damaged wiring found during the inspection.

5. Test and Replace Fuses

Check the fuse box for any blown fuses related to the interior lighting system.
Replace any blown fuses with the same amperage rating as specified in the owner’s manual.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Close all doors and test if the interior lights turn off after a few moments.
