Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and wiring harness repair kit.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Door Switches

Locate the door switches (usually mounted on the door frame).
- Sub-step 1: Remove the door panel if necessary to access the switch.
- Sub-step 2: Test the switch by pressing it manually; it should click and return to the original position.
- Sub-step 3: Use a multimeter to check for continuity when the switch is pressed.

3. Check Interior Light Switch Settings

Inspect the overhead console for the interior light switch.
- Sub-step 1: Set the switch to the "door" position.
- Sub-step 2: Close all doors and ensure the lights turn off; if not, proceed to the next step.

4. Examine the Wiring

Inspect the wiring harness leading to the interior lights and door switches.
- Sub-step 1: Look for any frayed wires, corrosion, or loose connections.
- Sub-step 2: Repair or replace any damaged wiring as necessary.

5. Test Body Control Module (BCM)

If previous steps do not resolve the issue, inspect the BCM.
- Sub-step 1: Use an OBD-II scanner to check for BCM error codes.
- Sub-step 2: If codes are present, address those specific issues according to manufacturer guidelines.
- Sub-step 3: Reprogram or replace the BCM if it is determined to be faulty.
