Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical hazards.
Ensure the vehicle is in a well-lit area to facilitate inspection.

2. Inspect Door Switches

Locate door switches for each door (typically found in the door frame).
Use a multimeter to check for continuity when the door is closed.
- Tool Required: Multimeter
If any switch shows no continuity when the door is closed, it may need replacement.

3. Check the Lighting Control Module

Access the lighting control module, usually located behind the dashboard or in the fuse panel.
Inspect for any visible damage or burnt connections.
If no damage is visible, use a scan tool to check for faults and reprogram if necessary.
- Tool Required: OBD-II scanner

4. Test the Dimmer Switch

Remove the dimmer switch from the dashboard.
Using a multimeter, test for proper resistance values across the terminals as per the service manual specifications.
Replace the dimmer switch if it does not meet specifications.

5. Reassemble and Connect Battery

Reinstall any components removed during inspection.
Reconnect the negative battery terminal and ensure all connections are secure.
