Inspect the wiring harness connected to the door and the interior lights.
- Sub-step: Look for frayed wires, corrosion, or loose connections.
Repair any damaged wires using wire strippers and connectors.
- Sub-step: Strip the insulation from the damaged section, twist the wires together, and cover with electrical tape or use heat shrink tubing.

5. Verify Functionality

Reconnect the negative battery terminal and test the interior lights.
Sub-step: Open and close the doors to ensure the lights turn off as expected.
