why does my Honda Civic interior light stay on when all doors are closed

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts while working on the vehicle.

2. Inspect and Replace Door Switches

1. Remove Door Panel:

   • Use a socket set to remove screws securing the door panel.
   • Carefully pry off the panel using a trim removal tool to avoid damaging clips.

2. Access Door Switch:

   • Locate the door switch mounted on the door frame or latch mechanism.
   • Disconnect the wiring harness from the switch.

3. Test the Door Switch:

   • Use a multimeter to check for continuity. If there is no continuity when the switch is pressed, replace the switch.

4. Replace the Door Switch:

   • If faulty, install a new door switch by connecting the wiring harness and securing it in place.

5. Reassemble Door Panel:

   • Reattach the door panel, ensuring all clips and screws are properly secured.

3. Check Wiring and Connections

1. Inspect Wiring:

   • Trace the wiring from the door switch to the body control module, looking for any broken or frayed wires.

2. Repair or Replace Wires:

   • If damaged, use appropriate automotive wire and connectors to repair or replace the wiring.

4. Test Interior Light Operation

• Reconnect the negative battery terminal and test the interior light functionality by opening and closing the doors.
