Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.

2. Inspect Door Latches

Open each door and inspect the latch mechanism.
Clean any dirt or debris from the latch and striker plate using a soft cloth.
Lubricate the latch mechanism with a silicone-based spray to ensure smooth operation.

3. Test and Replace Door Switches

Tools Required: Multimeter, flathead screwdriver, replacement door switch (if necessary).
Remove the door panel if required to access the door switch (consult repair manual for specific instructions).
Disconnect the door switch connector.
Use the multimeter to check for continuity when the switch is pressed and released.
- If there is no continuity when pressed, replace the switch.
Reinstall the new door switch by reversing the removal process.

4. Check Wiring and Connectors

Inspect the wiring harness for fraying, corrosion, or breaks.
If any issues are found, repair or replace the damaged wiring.
Ensure all connectors are secure and free from corrosion.

5. Reset the BCM

Disconnect the vehicle battery for 10 minutes to reset the body control module.
Reconnect the battery and check if the door ajar light is still illuminated.
