Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect Door Switches

Tools Required: Multimeter, screwdriver set.
Sub-steps:
1. Remove the door panel of each door to access the door latch and switch.
2. Disconnect the electrical connector from the door switch.
3. Use a multimeter to check for continuity across the switch when the door is closed. There should be continuity; if not, the switch may be faulty and should be replaced.
4. If the switch is functional, inspect the mounting area for debris or misalignment that could affect its operation.

3. Repair or Replace Faulty Components

Tools Required: Socket set, replacement door switch (if needed).
Sub-steps:
1. If a door switch is defective, remove the old switch by unscrewing it from the door latch assembly.
2. Install the new switch by securing it in place and reconnecting the electrical connector.
3. For any wiring issues found, repair or replace damaged wires and connectors as necessary.

4. Reassemble and Test

Tools Required: Screwdriver set.
Sub-steps:
1. Reattach the door panels carefully, ensuring all clips are secured.
2. Reconnect the vehicle's battery.
3. Test each door to ensure the warning light is no longer illuminated when the doors are closed.
