Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical shorts.
Tools Required: Screwdriver set, multimeter, OBD-II scanner.

2. Inspect and Test Door Switches

Remove the interior door panel to access the door switches.
Disconnect the wiring harness from each door switch.
Use a multimeter to test the continuity of each switch while pressing it; it should show continuity when pressed and none when released.
If a switch is faulty, proceed to replace it.

3. Replace Faulty Components

If any door switch is found defective, replace with a new part.
Reconnect the wiring harness and ensure it is secure.
Reinstall the door panel and ensure all clips and screws are properly secured.

4. Check Interior Light Switch

Locate the interior light switch, usually on the roof console.
If the switch is faulty, replace it by removing the console cover and disconnecting the wiring.
Install the new switch and reassemble the console.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Close all doors and check if the interior lights turn off after a few seconds.
If necessary, reset the vehicle's electrical system by turning the ignition on and off.
