Solution

1. Preparation

Gather tools and parts needed.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is in a well-lit area for visibility.

2. Inspect and Replace Door Switches

Tools Required: Flathead screwdriver, socket set, multimeter
Locate the door switch for each door (usually found near the door latch).
Use the flathead screwdriver to carefully pry off the trim panel if necessary.
Disconnect the switch connector and use the multimeter to test for continuity with the door closed and open.
If the switch is faulty, replace it with a new one.
Reconnect the switch and reassemble the door trim panel.

3. Test Interior Light Switch

Tools Required: None specifically, but a multimeter may be helpful.
Locate the interior light switch (usually near the light itself).
Ensure it is set to the "auto" or "off" position.
Test the switch function using the multimeter to ensure it is not stuck or malfunctioning.
Replace the switch if necessary.

4. Check Wiring and Connectors

Tools Required: Visual inspection tools, socket set
Inspect the wiring harness and connectors to the door switches for any signs of wear, damage, or corrosion.
Repair or replace any damaged wires or connectors to ensure proper electrical contact.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Close all doors and observe if the interior lights turn off as expected.
If the issue persists, consider reprogramming or updating the body control module.
