Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked in a well-lit area for visibility.

2. Inspect Door Switches

Locate the door switches in each door frame.
Remove the door panel if necessary using a socket set and trim removal tools.
Clean the switches and check for proper operation by manually activating them; replace if faulty.
Reassemble the door panel and reconnect any connectors.

3. Check Interior Light Switch

Locate the interior light control switch.
Ensure it is set to the "door" position; if it is stuck in the "on" position, free it and verify operation.
If the switch is defective, replace it with a new one.

4. Test Electrical System

Reconnect the negative battery terminal.
Use a multimeter to check the voltage at the interior light circuit.
If voltage is present when lights should be off, trace the circuit for shorts or faulty components.

5. Verify Repair

Test the interior lights by opening and closing each door to ensure they turn on and off properly.
Drive the vehicle and monitor the lights to confirm they do not stay on while in motion.
Check for any new fault codes after repairs with an OBD-II scanner.
