Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Safety glasses and gloves are recommended.

2. Inspect and Test Door Switches

Locate the door switches on each door (often integrated into the door latch).
Remove any trim panels as necessary to access the switches.
Use a multimeter to test the continuity of each switch when pressed. Replace any faulty switches.

3. Check and Repair Wiring

Follow the wiring harness from each door switch to the main body harness.
Look for signs of wear, frays, or disconnections.
Repair or replace damaged wiring as necessary to ensure proper connectivity.

4. Fuse Inspection

Locate the fuse box and identify the fuse linked to the interior lights and door switches.
Remove the fuse and inspect it for continuity; replace it if blown.
Reinstall the fuse and ensure it is seated correctly.

5. Reassemble and Test

Reassemble any panels that were removed during the inspection.
Reconnect the battery and test the operation of the interior lights by closing the doors.
Confirm that all lights turn off when doors are closed.
