Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, screwdriver set, and replacement door switches (if needed).
Ensure the vehicle is parked safely, with the ignition turned off.

2. Inspect Door Switches

Remove Door Panels: Using a screwdriver, carefully remove the screws securing the door panel. Gently pry off the panel using a trim removal tool.
Locate and Test Switches: Identify the door switch mechanism. Use a multimeter to check for continuity when the door is closed. If there is no continuity, the switch is faulty.
Replace Faulty Switches: If necessary, disconnect the wiring harness from the faulty switch and install the new switch. Reconnect the harness and ensure it fits securely.

3. Check Lighting Control Module

Access the Module: Locate the lighting control module, typically found under the dashboard or in the fuse box.
Inspect for Faults: Check for any visible damage, burnt connectors, or corrosion. Ensure all connections are secure.
Test Operation: If accessible, use an OBD-II scanner to check the module's functionality and reset any fault codes.

4. Reassemble Components

Reinstall Door Panels: Once repairs are complete, reattach the door panels by aligning them properly and securing them with screws.
Reconnect Battery: If disconnected, reconnect the vehicle's battery.
