Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked in a safe location with adequate lighting.

2. Inspect Door Switches

Remove the door panel for each affected door:
- Use a trim removal tool and a socket set to detach screws and clips.
Locate the door switch:
- Test the switch with a multimeter for continuity when pressed.
Clean or replace any faulty switches:
- If cleaning, use electrical contact cleaner.
- If replacing, install the new switch and reassemble the door panel.

3. Check and Reset Interior Light Control

Access the vehicle's iDrive system:
- Navigate to "Settings" > "Lighting" > "Interior Lighting."
Ensure all settings are correctly configured for automatic shut-off.
If settings appear correct, reset the system:
- Disconnect and reconnect the battery for a hard reset.

4. Test Battery and Fuses

Use a multimeter to check battery voltage:
- Voltage should be around 12.6 volts with the engine off.
Inspect the fuse box:
- Locate the fuse for interior lighting (refer to the owner's manual).
- Replace any blown fuses with the same amperage rating.

5. Inspect Wiring

Visually inspect wiring harnesses and connectors for damage:
- Look for frayed wires, exposed connections, or corrosion.
Repair or replace any damaged wiring as necessary.
