Solution

1. Preparation

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

2. Inspect Door Switches

Locate the door switches at each door frame.
Use a multimeter to test for continuity in each switch:
- Disconnect the switch from the wiring harness.
- Set the multimeter to the continuity setting.
- Press the switch; continuity should be present when pressed and absent when released.
Replace any faulty door switches.

3. Check Interior Light Switch

Locate the interior light switch, typically found on the overhead console.
Ensure the switch is in the "door" or "off" position.
If the switch appears defective, remove it by unscrewing or unclipping it from the console and replace it with a new one.

4. Examine Wiring and Connectors

Inspect the wiring harnesses connected to the door switches and interior lights.
Look for any frayed wires, shorts, or loose connections.
Repair or replace any damaged wiring as needed.

5. Reassemble and Test

Reconnect any switches or wiring that were disconnected during inspection.
Reconnect the negative battery terminal.
Test the interior lights by opening and closing each door to ensure they turn off as expected.
