Reassemble the door panel and reconnect any electrical connectors.

3. Check Dome Light Switch

Locate the dome light switch, usually located on the ceiling near the light fixture.
Ensure the switch is in the 'DOOR' position. If malfunctioning, replace it with a new switch.
Test functionality by toggling the switch.

4. Inspect Wiring

Visually inspect the wiring harness for any signs of wear, fraying, or shorts.
