Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, and replacement door switch (if necessary).
Disconnect the negative battery terminal to prevent electrical shorts while working.

2. Inspect Door Switches

Remove the door panel using a socket set to gain access to the door switch.
Disconnect the wiring harness from the door switch.
Use a multimeter to test the switch for continuity when depressed. Replace if defective.
Reinstall the door panel securely.

3. Check Door Latches

Open the affected doors and inspect the latches for proper alignment and functionality.
Lubricate the latch mechanism if sticking is observed.
Adjust the latch position if misalignment is found to ensure the door closes fully.

4. Examine Wiring Harness

Trace the wiring from the door switches to the body control module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace damaged wiring as needed.

5. Reset Body Control Module

Reconnect the negative battery terminal after completing repairs.
Reset the body control module by disconnecting the battery for 10 minutes, then reconnecting.
Test the interior lights by closing the doors to ensure they turn off properly.
