Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner.
Disconnect the negative battery terminal to prevent any electrical shorts while working.

2. Inspect Door Switches

Locate the door switches, usually found near the door latch.
Remove the door panel if necessary to access the switches.
Check for any physical damage or sticking; clean any debris or lubricate if necessary.
Test the switch with a multimeter to ensure it opens and closes properly. Replace if faulty.

3. Examine the Body Control Module (BCM)

Locate the BCM, typically found under the dashboard or behind the glove box.
Inspect the wiring harness for any signs of wear, corrosion, or loose connections.
If applicable, use the OBD-II scanner to check for BCM-related error codes.
If codes indicate a fault, consider reprogramming or replacing the BCM.

4. Check and Reset Fault Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and check if the dashboard lights turn off properly after the ignition is turned off.
