Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Adjust Door Switches

Locate the door switches on each door frame.
Remove any paneling covering the door switches if necessary.
Ensure that the switch is not stuck in the "on" position; press it manually to confirm it returns to "off."
Adjust the alignment of the switches if they are misaligned.

3. Test Interior Light Switch

Locate the interior light switch (usually on the ceiling or dashboard).
Use a multimeter to check for continuity in the switch when toggled.
If faulty, replace the switch with a new one following the manufacturer’s instructions.

4. Check and Repair Wiring

Inspect the wiring harness leading to the door switches.
Look for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring as needed.

5. Replace Fuse (If Necessary)

Locate the fuse box and identify the fuse related to interior lighting.
Remove the fuse and check for continuity using a multimeter.
If blown, replace it with a fuse of the same amperage.
