Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, screwdriver set, and replacement door switches if needed.
Ensure the vehicle is parked on a flat surface and turn off the ignition.

2. Inspect and Test Door Switches

Sub-step 1: Remove the door panel using a screwdriver to access the door switch.
Sub-step 2: Disconnect the door switch connector and use a multimeter to test for continuity when the switch is pressed.
Sub-step 3: If the switch fails the continuity test, replace it with a new unit.
Sub-step 4: Reconnect the door switch and reassemble the door panel.

3. Check Door Alignment and Latching Mechanisms

Sub-step 1: Open each door and visually inspect the alignment with the body of the vehicle.
Sub-step 2: If misaligned, adjust the hinges or latches as necessary.
Sub-step 3: Close the door and confirm it latches properly without gaps.

4. Test Lighting Control Module

Sub-step 1: If the switches and door alignment are fine, locate the lighting control module (usually near the fuse box).
Sub-step 2: Disconnect the module and inspect for burnt connectors or corrosion.
Sub-step 3: If damaged, replace the module with a compatible part and reconnect.
Sub-step 4: Recheck the operation of the interior lights.
