Solution

1. Preparation

Gather necessary tools: screwdriver set, multimeter, and a flashlight.
Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect and Test Door Switches

Remove the door panel to access the door switch. Use a screwdriver to carefully detach any screws and clips.
Locate the door switch and disconnect the wiring harness.
Use a multimeter to test the switch. Set the multimeter to continuity mode and press the switch; it should show continuity when pressed and none when released.
If the switch is faulty, replace it with a new one.

3. Check Wiring and Connectors

Visually inspect the wiring harness connected to the door switch for any signs of fraying or breakage.
Ensure all connectors are securely attached without corrosion or loose connections.
Repair any damaged wiring as necessary, using appropriate repair connectors or electrical tape to secure.

4. Reassemble and Test

Reconnect the door switch and reattach the door panel, ensuring all clips and screws are secure.
Reconnect the negative battery cable.
Test the interior lights by opening and closing the doors to confirm they turn off appropriately.
