1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required:

OBD-II scanner
Multimeter
Screwdrivers (Phillips and flathead)
Socket set
Wire brush or contact cleaner

2. Inspect and Test Door Switches

Remove the door panel carefully using a screwdriver to access the door switch.
Disconnect the electrical connector from the door switch.
Using a multimeter, test the switch for continuity when pressed. If it does not show continuity, replace the switch.
Clean any corrosion from the terminals with a wire brush or contact cleaner before reassembling.

3. Check Door Latch Mechanisms

Inspect each door latch for proper alignment and function.
Manually operate the latch to ensure it fully engages and releases smoothly.
If the latch is faulty, remove it by unscrewing and replace it with a new one according to manufacturer specifications.

4. Inspect Wiring and Connectors

Trace the wiring harness from the door switches to the main body of the vehicle.
Look for any frayed wires, loose connections, or signs of wear.
Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Close all doors and check if the interior lights turn off.
Perform a test drive to ensure the issue is resolved.
