Solution

1. Preparation

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

2. Inspect Door Switches

Tools Required: Screwdriver set, multimeter
Remove the door panel using a screwdriver to access the door switch.
Disconnect the connector from the door switch.
Use a multimeter to check the continuity of the switch; it should show continuity when pressed and none when released.
If faulty, replace the door switch with a new one.

3. Check Interior Light Switch

Locate the interior light switch, usually found near the ceiling or on the light assembly.
Ensure the switch is set to the "Door" position rather than "On".
If the switch is faulty, replace it with a compatible part.

4. Inspect Wiring and Connectors

Visually inspect wiring harnesses for any signs of wear, fraying, or damage.
Pay special attention to the wiring around the door hinges, where it may be subject to wear.
Repair or replace any damaged wiring or connectors as necessary.

5. Reassemble and Test

Reattach the door panels and any components removed during inspection.
Reconnect the negative battery terminal.
Test the interior lights by closing all doors to ensure they turn off as expected.
