Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the vehicle battery to prevent electrical shorts.

2. Inspect and Repair Door Switches

Tools Required: Screwdriver set, multimeter
Remove the door panel from the affected doors to access the door switches.
Inspect the door switches for proper operation; test with a multimeter to confirm they are functioning correctly.
If faulty, replace the door switch with a new one, ensuring it is properly aligned and secured.
Reinstall the door panel securely.

3. Check Interior Light Circuit

Tools Required: Multimeter
Reconnect the vehicle battery and turn on the ignition.
Use the multimeter to test the voltage at the interior light fixture; it should read approximately 12 volts.
If voltage is present when the switch is set to "door," there may be a fault in the body control module or wiring.
Inspect wiring for any damage and repair as necessary.

4. Examine Body Control Module

Tools Required: OBD-II scanner, socket set
Connect the OBD-II scanner to the vehicle’s diagnostic port and retrieve any fault codes related to the body control module.
If issues are detected, consider reprogramming or replacing the body control module as per manufacturer specifications.
Follow the appropriate procedures for programming if a new module is installed.
